[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] <Terminology> In this specification, "well-being" refers to a person's physical, mental, and social well-being. It has been widely used since the World Health Organization (WHO) drafted its constitution in 1946, stating that "health is a state of physical, mental, and social well-being (omitted)." In this specification, "psychological well-being" refers to a person's subjective well-being, that is, a state of good mental health and how one feels about oneself. Furthermore, in psychology, Ryan et al. (2001). Annual review of psychology, 52, 141-166) broadly divide psychological well-being into two categories: eudaimonic well-being and hedonic well-being. For example, eudaimonic refers to self-affirmation and positive relationships with others that arise in everyday life, while hedonic refers to positive emotions such as vitality, happiness, and satisfaction that arise in daily life. These two aspects are also interrelated.

[0011] First, we will explain the surveys and experiments that have revealed the relationship between psychological well-being and awareness of skin, the relationship between psychological well-being and awareness of at least one of health methods, beauty methods, skin care, and makeup, and the relationship between psychological well-being and physiological data of skin.

[0012] <The relationship between psychological well-being and skin awareness> The following questions were asked to 550 Japanese women (aged 20 to 75). The Psychological Well-being Scale (Nishida Yukiko, 2000, A Study on Diverse Lifestyles and Psychological Well-being in Adult Women, Educational Psychology Research, 48(4), 433-443) is a well-known psychological survey question related to psychological well-being. It contains 43 questions related to six factors: "personal growth," "purpose in life," "autonomy," "self-acceptance," "environmental control," and "positive relationships with others." Subjects responded to each question with responses such as "very applicable" or "not applicable at all." The Japanese Subjective Happiness Scale (Shimai Satoshi, Otake Keiko, Utsugi Seisuke, Ikemi Akira, 2004, Examination of the Reliability and Validity of the Japanese Subjective Happiness Scale (SHS), Japanese Journal of Public Health, 51(10), 845-853) also contains four questions, such as "Overall, I consider myself to be ( )" (subjects chose from "very unhappy" to "very happy"). The questions regarding skin awareness included positive skin awareness (10 items related to skin condition such as color (e.g., luster and brightness), texture (e.g., softness), and shape (e.g., contours)), negative skin awareness (12 items related to skin condition such as surface (e.g., pores and roughness), and sensitivity (e.g., itching and pain), and questions regarding skin aging awareness (10 items related to skin condition such as shape (e.g., wrinkles and sagging), and color (e.g., spots and freckles). Subjects responded to the questions with responses such as "very applicable" or "not applicable at all."

[0013] "Psychological well-being (a numerical score of the subject's response to questions about psychological well-being)," "positive skin consciousness (a numerical score of the subject's response to questions about positive skin consciousness)," "negative skin consciousness (a numerical score of the subject's response to questions about negative skin consciousness)," and "awareness of skin aging (a numerical score of the subject's response to questions about awareness of skin aging)" were assumed as latent factors, and a causal relationship was assumed between "psychological well-being" as the result and "positive skin consciousness," "negative skin consciousness," and "awareness of skin aging" as the cause. Analysis assuming a causal relationship showed that "positive skin consciousness" had a positive impact of 0.38 on "psychological well-being." Furthermore, "negative skin consciousness" had a negative impact of 0.23 on "psychological well-being." Furthermore, "awareness of skin aging" had a positive impact of 0.01 on "psychological well-being." Additionally, the subject's age had a positive effect of 0.12 on "psychological well-being." These findings suggest that in order to improve psychological well-being, it is important to increase positive awareness of skin, and secondarily, to decrease negative awareness of skin.

[0014] Figure 1 shows the results of dividing psychological well-being into three levels (low (124 points or less), medium (125-177 points), and high (178 points or more)) using the mean plus one standard deviation and the mean minus one standard deviation of the scores quantified from the subjects' responses to questions about psychological well-being as dividing points. Among 550 Japanese women (aged 20 to 75), 57 were in the "low" category, 410 in the "medium" category, and 83 in the "high" category. For each level, the mean values ​​for each awareness (i.e., "positive skin awareness," "negative skin awareness," and "awareness of skin aging") were calculated. Next, the mean values ​​for two levels, "low and medium," and "medium and high," were calculated. From these mean values, the range of scores for each awareness of skin corresponding to each level of psychological well-being was calculated.

[0015] For example, using the correspondence of scores as shown in FIG. 1, it is possible to evaluate psychological well-being based on skin awareness, and to evaluate skin awareness based on psychological well-being.

[0016] The relationship between psychological well-being and awareness of at least one of health regimes, beauty regimes, skin care, and makeup. The following questions were asked to 550 Japanese women (aged 20 to 75). The Psychological Well-being Scale, known in the field of psychology as a question on psychological well-being (Nishida Yukiko (2000). Study on the Diverse Lifestyles and Psychological Well-being of Adult Women. Educational Psychology Research, 48(4), 433-443.), includes 43 questions on six factors: "personal growth," "purpose in life," "autonomy," "self-acceptance," "environmental control," and "positive relationships with others." Subjects responded to the questions with responses such as "very applicable" or "not applicable at all." The questions regarding awareness of at least one of health, beauty, skincare, and makeup were about not being aware of at least one of health, beauty, skincare, and makeup that is suitable for oneself (seven items: "I don't know what beauty method suits me," "I don't know what health method suits me," "I can't practice health," "I can't keep up with beauty," "I've given up on beauty," "I don't know what skincare is suitable," and "I don't know what makeup is suitable"), as well as questions regarding awareness of health ("Taking on a health challenge," "Trying popular health methods and health products," "Spending time on health," "Exchange information for health," "Spending money on health," "Exercising for health," "I'm interested in health trends"). The survey included eight items: "I enjoy makeup," "I feel confident through makeup," "I add individuality through makeup," "I actively wear makeup," "I use makeup creatively," "I feel confident through skin care," "I enjoy skin care," "I actively use skin care," and "I change my makeup depending on the occasion"; and seven items: "Posture and walking style are related to health," "Health comes first," "Daily efforts to stay healthy," "The relationship between beauty and health," "Continuous efforts to stay healthy," "Beautiful bare skin," and "Continuous efforts to be beautiful." Subjects responded to the questions with options such as "very applicable" or "not at all applicable."

[0017] "Psychological well-being (a numerical score of the subject's response to a question about psychological well-being)," "Not being aware of at least one of the following health and beauty methods, skin care and makeup that are suitable for oneself (a numerical score of the subject's response to a question about not being aware of at least one of the following health and beauty methods, skin care and makeup that are suitable for oneself)," "health awareness (a numerical score of the subject's response to a question about health awareness)," "cosmetics (skin care and makeup) awareness (a numerical score of the subject's response to a question about awareness of cosmetics (skin care and makeup))," and "awareness of the relationship between health and beauty (a numerical score of the subject's response to a question about awareness of the relationship between health and beauty)" were assumed to be latent factors, and a statistical method called structural equation modeling was used to analyze "psychological well-being" as an outcome, assuming a causal relationship between "not being aware of at least one of the following health and beauty methods, skin care and makeup that are suitable for oneself," "health awareness," "cosmetics (skin care and makeup) awareness," and "awareness of the relationship between health and beauty" as causes. As a result of an analysis assuming causal relationships, "not being aware of at least one of the following health methods, beauty methods, skin care, and makeup that are suitable for oneself" had a negative impact of 0.51 on "psychological well-being." Furthermore, "awareness of the relationship between health and beauty" had a positive impact of 0.31 on "psychological well-being." Furthermore, "health awareness" had a positive impact of 0.21 on "psychological well-being." Furthermore, "awareness of cosmetics (skin care and makeup)" had a positive impact of 0.14 on "psychological well-being." Furthermore, the subject's age had a positive impact of 0.04 on "psychological well-being." Furthermore, the number of vague complaints the subject had suggested had a negative impact of 0.14 on "psychological well-being."From these findings, it was found that in order to improve psychological well-being, it is important to reduce the lack of awareness of at least one of the health methods, beauty methods, skin care, and makeup that are suitable for oneself, and next, it is important to increase awareness of health, awareness of cosmetics (skin care and makeup), and awareness of the relationship between health and beauty.

[0018] Figure 2 shows the results of dividing psychological well-being into three levels (low (137 points or less), intermediate (138-189 points), and high (190 points or more)) using the mean plus one standard deviation and the mean minus one standard deviation of the scores quantified from the subjects' responses to questions about psychological well-being as dividing points. Among 550 Japanese women (aged 20 to 75), 46 were in the "low" category, 423 in the "intermediate" category, and 81 in the "high" category. For each level, the mean values ​​for each awareness (i.e., "not being aware of at least one of the following health and beauty methods, skin care, and makeup that are suitable for oneself," "health awareness," "awareness of cosmetics (skin care and makeup)," and "awareness of the relationship between health and beauty") were calculated. Next, the mean values ​​for the two levels, "low and intermediate" and "intermediate and high," were calculated. From these means, the range of scores for each awareness corresponding to each level of psychological well-being was calculated.

[0019] For example, using the correspondence between scores as shown in Figure 2, it is possible to evaluate psychological well-being based on awareness of at least one of health methods, beauty methods, skin care, and makeup, and to evaluate awareness of at least one of health methods, beauty methods, skin care, and makeup based on psychological well-being.

[0020] <The relationship between psychological well-being and physiological skin data> Fifty-two Japanese women (aged 25 to 43 years, mean age 34.7±5.4 years) were surveyed four times in the spring (April and mid-May) and summer (June and mid-July). Questions about psychological well-being (eudaimonic and hedonic) were asked, and skin physiological measurements were also taken on the cheek and inner arm (inside of the forearm). Regarding skin physiological measurements, each measurement item was standardized for each month, taking into account differences due to seasonal factors.

[0021] <<The relationship between eudaimonic well-being and skin firmness, and the relationship between eudaimonic well-being and yellow skin tone>> A multiple regression analysis was performed with psychological well-being (eudaimonic well-being) as the dependent variable and facial skin as the explanatory variable, and found a correlation between psychological well-being (eudaimonic well-being) and facial skin firmness. Furthermore, a multiple regression analysis was performed with psychological well-being (eudaimonic well-being) as the dependent variable and arm skin as the explanatory variable, and found a correlation between psychological well-being (eudaimonic well-being) and the yellowness of arm skin. Incidentally, when age was included as an explanatory variable to reflect the influence of age, a correlation was observed between psychological well-being (eudaimonic well-being) and facial skin firmness and the yellowness of arm skin, improving accuracy. (However, even without including age as an explanatory variable to reflect the influence of age, a correlation was observed between psychological well-being (eudaimonic well-being) and facial skin firmness and the yellowness of arm skin.)

[0022] Figure 3 shows the results of dividing psychological well-being (eudaimonic well-being) into three levels (low well-being (86 points or less), average well-being (87 to 117 points), and high well-being (118 points or more)) using the mean plus one standard deviation and the mean minus one standard deviation of the scores quantified from the subjects' responses to questions about psychological well-being. Among Japanese women (52 people aged 25 to 43 (mean age 34.7 ± 5.4 years), measured four times (number of cases = 208)), there were 26 cases of low well-being, 149 cases of average well-being, and 33 cases of high well-being.

[0023] For each stage, the average value of cheek skin firmness (the sum of "net elasticity," "viscoelasticity," and negative "skin softness (ease of skin stretching)") was calculated. Next, the average values ​​for the two stages, "low well-being vs. average well-being" and "average well-being vs. high well-being," were calculated. From these average values, the range of cheek skin firmness scores corresponding to each stage of psychological well-being (eudaimonic well-being) was calculated.

[0024] For each level, the average value of the yellowness of the arm skin (the sum of "Chroma," "Melanin," and "Yellowness (b*)") was calculated. Next, the average values ​​for the two levels, "Low Well-being vs. Average Well-being" and "Average Well-being vs. High Well-being," were calculated. From these average values, the range of the yellowness score for the arm skin corresponding to each level of psychological well-being (eudaimonic well-being) was calculated.

[0025] Questions regarding psychological well-being (eudaimonic well-being) were taken from the shortened version of the Psychological Well-Being Scale, known in the field of psychology (Iwano Taku et al. (2015). Development of a Short Version of the Psychological Well-Being Scale. Behavioral Science, 54(1), 9-21.), which includes 24 questions relating to six factors: "personal growth," "purpose in life," "autonomy," "self-acceptance," "environmental control," and "positive relationships with others." Subjects responded to the questions with responses such as "very applicable" or "not applicable at all."

[0026] For example, using the score correspondence shown in Figure 3, it is possible to evaluate psychological well-being based on physiological skin data (skin firmness), and to evaluate physiological skin data (skin firmness) based on psychological well-being. For example, when measuring skin firmness (A1: net elasticity, B1: viscoelasticity, C1: skin softness (ease of skin pulling)), psychological well-being can be estimated and evaluated based on the total score applied to the following formula: Calculate each standard score using formula 1: (A1, B1, C1 - average value) ÷ standard deviation (see Figures 5 and 6). Equation 2: Add up the standard scores of A1, B1, and negative C1 obtained from Equation 1.

[0027] For example, using the score correspondence shown in Figure 3, it is possible to evaluate psychological well-being based on physiological skin data (yellowness of the skin) and to evaluate physiological skin data (skin color (yellowness)) based on psychological well-being. For example, when measuring the yellowness of the skin (A2: chroma, B2: melanin, C2: yellowness value (b*)), psychological well-being can be estimated and evaluated based on the total score applied to the following formula. Calculate each standard score using formula 1: (A2, B2, C2 - average value) ÷ standard deviation (see Figures 5 and 6). Formula 2: Add up the standard scores for A2, B2, and C2 obtained in Formula 1.

[0028] <<The relationship between hedonic well-being and skin firmness>> A multiple regression analysis was performed with psychological well-being (hedonic well-being) as the dependent variable and facial skin as the explanatory variable, and found a correlation between psychological well-being (hedonic well-being) and facial skin firmness. Furthermore, when age was included as an explanatory variable to account for the influence of age, a correlation between psychological well-being (hedonic well-being) and facial skin firmness was also observed, improving accuracy. (However, even when age was not included as an explanatory variable to account for the influence of age, a correlation between psychological well-being (hedonic well-being) and facial skin firmness was observed.)

[0029] Figure 4 shows the results of dividing psychological well-being (hedonic well-being) into three levels (low well-being (16 points or less), average well-being (17 to 24 points), and high well-being (25 points or more)) using the mean plus one standard deviation and the mean minus one standard deviation of the scores quantified from the subjects' responses to questions about psychological well-being. Among Japanese women (52 people aged 25 to 43 (mean age 34.7 ± 5.4 years), measured four times (number of cases = 208)), there were 38 cases of low well-being, 140 cases of average well-being, and 30 cases of high well-being.

[0030] For each stage, the average value of cheek skin firmness (the sum of "net elasticity," "viscoelasticity," and negative "skin softness (ease of skin stretching)") was calculated. Next, the average values ​​for the two stages, "low well-being and average well-being" and "average well-being and high well-being," were calculated. From these average values, the range of cheek skin firmness scores corresponding to each stage of psychological well-being (hedonic well-being) was calculated.

[0031] The questions regarding psychological well-being (hedonic well-being) included 12 questions related to two factors, "positive emotions" and "negative emotions," using the emotional well-being scale known in the field of psychology (Nakahara Jun (2011). Examination of the factor structure of the emotional well-being scale and creation of a shortened version. Gerontological Social Science, 32(4), 434-442.). Subjects responded to the questions with responses such as "I always felt that way" or "I never felt that way."

[0032] For example, using the score correspondence shown in Figure 4, it is possible to evaluate psychological well-being based on physiological skin data (skin firmness), and to evaluate physiological skin data (skin firmness) based on psychological well-being. For example, when measuring skin firmness (A3: net elasticity, B3: viscoelasticity, C3: skin softness (ease of skin pulling)), psychological well-being can be estimated and evaluated based on the total score applied to the following formula: Calculate each standard score using formula 1: (A3, B3, C3 - average value) ÷ standard deviation (see Figures 5 and 6). Equation 2: Add up the standard scores for A3, B3, and negative C3 obtained in Equation 1.

[0033] Fig. 5 is a diagram illustrating physiological data (firmness and yellowness) of skin by temperature (for three patterns) according to an embodiment of the present invention. The example in Fig. 5 shows the range of the average value and standard deviation when the temperature is divided into three patterns (less than 10°C, 10°C to less than 20°C, and 20°C or more).

[0034] Fig. 6 is a diagram illustrating physiological data (firmness and yellowness) of skin by temperature (for two patterns) according to an embodiment of the present invention. The example in Fig. 6 shows the range of the average value and the standard deviation when the temperature is divided into two patterns (below 10°C and above 10°C).

[0035] In one embodiment of the present invention, the skin firmness values ​​("net elasticity", "viscoelasticity", "skin softness (ease of skin stretching)") and the skin yellowness values ​​("chroma", "melanin value", "yellowness value (b*)") are standardized using the average value and standard deviation for each temperature, thereby adjusting for differences due to temperature.

[0036] FIG. 7 is a diagram illustrating the relationship between changes in physiological data (firmness) of the skin and changes in psychological well-being according to one embodiment of the present invention.

[0037] 1. The subjects (control group (21 people), new beauty method group (22 people)) performed skin care every morning and evening for five weeks using lotion, emulsion, and cream. The control group and new beauty method group used the same lotion, emulsion, and cream. For the first 2.5 weeks, the new beauty method group performed the same skin care as the control group, but for the last 2.5 weeks, they performed light stretching after applying lotion, deep breathing when applying emulsion, and massage when applying the cream. 2. Changes in skin firmness and psychological well-being (eudaimonic well-being) due to skin care were calculated. · Firmness of facial skin After standardizing "net elasticity," "viscoelasticity," and "skin softness (ease of pulling the skin)" before and five weeks after the cosmetic treatment, "net elasticity," "viscoelasticity," and negative "skin softness (ease of pulling the skin)" are summed. Psychological well-being A numerical score is calculated based on the subjects' answers to questions about psychological well-being (eudaimonic well-being). 3. The correlation coefficient showing the relationship between changes in psychological well-being (eudaimonic well-being) due to skin care and changes in facial skin firmness was calculated (see Figure 7). 4. In the new beauty regimen group, a significant positive correlation (r=0.43, p<0.05*) was observed between the change (ratio) in facial skin firmness and the change (difference) in psychological well-being (eudaimonic well-being) due to skin care (see Figure 7). 5. In this way, it was found that when facial skin firmness improves with morning and evening skin care, psychological well-being (eudaimonic well-being) also improves, or alternatively, when psychological well-being (eudaimonic well-being) improves with morning and evening skin care, facial skin firmness improves.

[0038] <<Relationship between Subjective Health Scale (SHS) and Skin Roughness>> A multiple regression analysis was performed with psychological well-being (subjective happiness scale) as the dependent variable and facial skin as the explanatory variable, and it was found that psychological well-being (subjective happiness scale) was correlated with facial skin roughness. Furthermore, when age was included as an explanatory variable to account for the influence of age, a correlation between psychological well-being (subjective happiness scale) and facial skin roughness was also observed, improving accuracy. (However, even when age was not included as an explanatory variable to account for the influence of age, a correlation between psychological well-being (subjective happiness scale) and facial skin roughness was observed.)

[0039] Figure 8 shows the results of dividing the Subjective Well-Being Scale (SHS) into three levels (low subjective well-being (13 points or less), average subjective well-being (14 to 24 points), and high subjective well-being (25 points or more)) using the mean plus one standard deviation and the mean minus one standard deviation of the scores (raw scores) that quantified the subjects' responses to questions on the SHS as dividing points. Among Japanese women (19 people aged 25 to 35 (mean age 30.7 ± 3.0 years), measured four times (number of cases = 76)), there were 9 cases of low subjective well-being, 57 cases of average subjective well-being, and 10 cases of high subjective well-being.

[0040] The average degree of cheek roughness was calculated for each level. Next, the average values ​​for the two levels of "low subjective well-being and average subjective well-being" and "average subjective well-being and high subjective well-being" were calculated. From these average values, the range of cheek roughness scores corresponding to each level of the Subjective Well-Being Scale (SHS) was calculated.

[0041] Furthermore, questions regarding psychological well-being (Subjective Health Status Scale (SHS)) included four questions such as, "In general, I consider myself to be ( )" (subjects chose between "very unhappy" and "very happy").

[0042] For example, using the correspondence between scores as shown in Figure 8, it is possible to evaluate psychological well-being based on physiological skin data (skin roughness), and evaluate physiological skin data (skin roughness) based on psychological well-being.

[0043] The evaluation method using the above results (each correlation) will be described in detail below. In the present invention, evaluation can be performed using the above results (each correlation).

[0044] <Method> FIG. 9 is a flowchart of an evaluation process according to one embodiment of the present invention.

[0045] In step 1 (S1), information or data to be used in the evaluation is obtained.

[0046] In step 2 (S2), an evaluation is made based on the information or data.

[0047] In step 3 (S3), recommendations are made to improve psychological well-being.

[0048] Each evaluation process will be described in detail below.

[0049] First, we will explain the information and data used in the evaluation, which will be divided into [information on skin awareness], [information on awareness of at least one of health methods, beauty methods, skin care, and makeup], [physiological data on skin], and [information on psychological well-being].

[0050] [Skin Awareness Information] Skin awareness information can include positive skin awareness (i.e., awareness of good skin condition), negative skin awareness (i.e., awareness of poor skin condition), and skin aging awareness (i.e., awareness of changes in skin due to aging).

[0051] The information on skin awareness is the results of responses by the subject 20 to questions (e.g., "very applicable," "not applicable at all," etc.). The questions may include questions regarding positive skin awareness (e.g., 10 items on skin condition related to color such as luster and brightness, texture such as softness, and shape such as contour), questions regarding negative skin awareness (e.g., 12 items on skin condition related to surface such as pores and roughness, and sensitivity such as itching and pain), and questions regarding awareness of skin aging (e.g., 10 items on skin condition related to shape such as wrinkles and sagging, and color such as spots and freckles).

[0052] [Information about awareness of at least one of health methods, beauty methods, skin care, and makeup] Information regarding awareness of at least one of health methods, beauty methods, skin care, and makeup can include information regarding not being aware of at least one of health methods, beauty methods, skin care, and makeup that is suitable for oneself, awareness of health, awareness of cosmetics (skin care and makeup), and awareness of the relationship between health and beauty.

[0053] Information on awareness of at least one of health methods, beauty methods, skin care, and makeup is the result of responses by the subjects 20 to questions (e.g., "very applicable," "not applicable at all," etc.). The questions consisted of questions about not being aware of at least one of health methods, beauty methods, skin care, and makeup that is suitable for oneself (e.g., seven items: "not sure which beauty method suits me," "not sure which health method suits me," "can't keep up with beauty," "given up on beauty," "not sure which skin care method suits me," and "not sure which makeup method suits me") and questions about awareness of health (e.g., "challenges for health," "trying popular health methods and health products," "spending time on health," "exchanging information for health," "spending money on health," "exercising for health," "interested in health trends," "taking specified health foods and supplements"). " (8 items), questions about attitudes toward cosmetics (skin care and makeup) (e.g., nine items: "Makeup is fun," "Confident with makeup," "Individuality with makeup," "Actively using makeup," "Making creative use of makeup," "Confident with skin care," "Skin care is fun," "Actively using skin care," and "Varying makeup depending on the occasion"), and questions about attitudes toward the relationship between health and beauty (e.g., seven items: "Posture and walking style are related to health," "Health comes first," "Daily efforts to stay healthy," "The relationship between beauty and health," "Continuous efforts to stay healthy," "Beauty of bare skin," and "Continuous efforts to be beautiful").

[0054] [Skin physiological data] For example, the skin physiological data may be at least one of the subject's 20 skin firmness (e.g., facial skin firmness), skin color (e.g., facial skin yellowness, arm skin yellowness), and skin roughness (e.g., facial skin roughness).

[0055] For example, skin firmness (e.g., facial (e.g., cheek) skin firmness) represents the sum of "net elasticity," "viscoelasticity," and negative "skin softness (ease of skin stretching)." Higher values ​​indicate firmer skin, while lower values ​​indicate less firm skin. For example, skin firmness can be obtained using a device that measures skin viscoelasticity.

[0056] "Net elasticity" is one of the indicators of skin viscoelasticity.

[0057] "Viscoelasticity" is one of the indicators of skin viscoelasticity.

[0058] "Skin softness (ease of skin stretching)" is one of the indicators of skin viscoelasticity.

[0059] For example, skin color (specifically, yellowness) represents the sum of "chroma," "melanin value," and "yellowness value (b*)." For example, skin color (specifically, yellowness) can be obtained by a device that irradiates light onto the skin and calculates the skin color from the reflected light.

[0060] "Saturation" indicates the vividness of skin color.

[0061] "Melanin value" indicates the amount of melanin pigment in the skin.

[0062] The higher the "yellowness value," the more yellow it is, and the lower the value, the more blue it is.

[0063] For example, skin roughness (e.g., the roughness of the skin on the face (e.g., cheeks)) indicates the degree of unevenness of the skin. A higher value indicates a larger area of ​​unevenness on the skin, and a lower value indicates a smaller area of ​​unevenness on the skin. For example, skin roughness can be obtained by a device that analyzes an image of the skin.

[0064] [Psychological Well-Being Information] Information on psychological well-being is the results of the subjects' responses to questions (e.g., "very applicable" or "not applicable at all"). The Psychological Well-Being Scale (Nishida Yukiko, 2000). A study on diverse lifestyles and psychological well-being among adult women. Educational Psychology Research, 48(4), 433-443.) is a well-known psychological well-being scale. It contains 43 questions related to six factors: "personal growth," "purpose in life," "autonomy," "self-acceptance," "environmental control," and "positive relationships with others." A shortened version of this Psychological Well-Being Scale (Iwano Taku et al., 2015). Development of a shortened version of the Psychological Well-Being Scale. Behavioral Science, 54(1), 9-21.) also contains 24 questions related to the same six factors. Questions about psychological well-being (hedonic well-being) can include 12 questions about two factors, "positive emotions" and "negative emotions," using the Emotional Well-being Scale known in the field of psychology (Nakahara Jun (2011). Examination of the factor structure of the Emotional Well-being Scale and creation of a shortened version. Gerontological Social Science, 32(4), 434-442.). Subjects respond to the questions with responses such as "I always felt that way" or "I never felt that way."

[0065] In addition to the questions regarding the six factors above, the following questions (Subjective Happiness Scale (SHS)) may also be used (Japanese version of the Subjective Happiness Scale (Shimai Satoshi, Otake Keiko, Utsugi Seisuke, Ikemi Akira (2004). Examination of the reliability and validity of the Japanese version of the Subjective Happiness Scale (SHS). Japanese Journal of Public Health, 51(10), 845-853.). 1. Generally speaking, I think of myself as ( ). Answer: 7-point scale from "very unhappy person" to "very happy person" 2. Compared to people my age, I consider myself to be ( ). Answer: 7-point scale from "unhappier people" to "happier people" 3. Generally speaking, there are people who are very happy. They find the best in every situation and enjoy life. To what extent do you share these characteristics? Answers: 7-point scale ranging from "not at all" to "very much" 4. There are people who are generally very unhappy. They are not depressed, but they seem much less happy than others would expect. To what extent do you share this characteristic? Answers: 7-point scale ranging from "not at all" to "very much"

[0066] Next, evaluation and recommendations based on the above information or data will be described.

[0067] <<Evaluation and recommendations for psychological well-being based on skin awareness>> The following describes the evaluation and recommendation of psychological well-being based on skin awareness. First, information on the subject's 20 skin awareness is obtained. Next, the subject's 20 psychological well-being is evaluated based on the information on the subject's 20 skin awareness. Next, based on the results of the psychological well-being evaluation, one or more of skin care, makeup, and beauty methods that will change the subject's 20 skin awareness are recommended.

[0068] [evaluation] For example, the answers of the subject 20 to the questions can be quantified, and the subject can be classified into psychological well-being groups corresponding to the numerical values ​​of the answers to the questions (e.g., a group with low psychological well-being, a group with high psychological well-being, and a group with intermediate psychological well-being (between low and high)). Specifically, the higher the positive skin awareness (i.e., awareness of good skin condition), the higher the psychological well-being (i.e., the subject 20 is in a good psychological state). On the other hand, the higher the negative skin awareness (i.e., awareness of poor skin condition), the lower the psychological well-being (i.e., the subject 20 is in a poor psychological state).

[0069] For example, the psychological well-being of subject 20 can be assessed based on subject 20 being more aware of the good condition of their skin than of the bad condition of their skin (e.g., by giving greater weight to answers to questions regarding positive skin awareness than to answers to questions regarding negative skin awareness).

[0070] For example, the psychological well-being of the subject 20 can be evaluated further based on the degree of aging of the subject 20. Specifically, the older the subject 20 is, the higher the psychological well-being (i.e., the subject 20 is in a good psychological state) can be evaluated. In this case, the age of the subject 20 is assumed to be acquired.

[0071] [Recommended] For example, one or more of skin care, makeup, and beauty methods that increase positive skin awareness (awareness of good skin condition) and decrease negative skin awareness (awareness of poor skin condition) may be recommended. Note that information on recommended skin care, makeup, and beauty methods may be determined in advance for each psychological well-being group (e.g., a group with low psychological well-being, a group with high psychological well-being, and a group with intermediate psychological well-being (between low and high)).

[0072] <<Skin awareness evaluation and recommendations based on psychological well-being>> The evaluation and recommendation of skin awareness based on psychological well-being will be described. First, information on the psychological well-being of the subject 20 is obtained. Next, the subject 20's awareness of skin is evaluated based on the information on the psychological well-being of the subject 20. Next, based on the results of the evaluation of skin awareness, one or more of skin care, makeup, and beauty methods that will change the subject 20's awareness of skin are recommended.

[0073] <<Evaluation and recommendation of psychological well-being based on awareness of at least one of health regimes, beauty regimes, skin care, and makeup>> The following describes evaluation and recommendation of psychological well-being based on awareness of at least one of health regimens, beauty regimens, skin care, and makeup. First, information on awareness of at least one of health regimens, beauty regimens, skin care, and makeup of subject 20 is obtained. Next, the psychological well-being of subject 20 is evaluated based on the information on awareness of at least one of health regimens, beauty regimens, skin care, and makeup of subject 20. Next, based on the results of the psychological well-being evaluation, one or more of skin care, makeup, and beauty regimens that will change subject 20's awareness of at least one of health regimens, beauty regimens, skin care, and makeup are recommended.

[0074] [evaluation] For example, the answers of the subject 20 to the questions can be quantified, and the subject can be classified into psychological well-being groups corresponding to the numerical values ​​of the answers to the questions (e.g., a group with low psychological well-being, a group with high psychological well-being, or a group with intermediate psychological well-being (between low and high)). Specifically, the less aware a subject is of at least one of health methods, beauty methods, skin care, and makeup that are suitable for them, the lower their psychological well-being can be evaluated (i.e., the subject 20 is not in a good psychological state). Furthermore, the more health-conscious a subject is, the higher their psychological well-being can be evaluated (i.e., the subject 20 is in a good psychological state). Furthermore, the more aware a subject is of cosmetics (skin care and makeup), the higher their psychological well-being can be evaluated (i.e., the subject 20 is in a good psychological state). Furthermore, the more aware a subject is of the relationship between health and beauty, the higher their psychological well-being can be evaluated (i.e., the subject 20 is in a good psychological state).

[0075] [Recommended] For example, one or more of skin care, makeup, and beauty methods may be recommended so that the user can recognize at least one of the health method, beauty method, skin care, and makeup that is suitable for the user. Furthermore, for example, one or more of skin care, makeup, and beauty methods that increase awareness of health may be recommended. Furthermore, for example, one or more of skin care, makeup, and beauty methods that increase awareness of cosmetics (skin care and makeup) may be recommended. Furthermore, for example, one or more of skin care, makeup, and beauty methods that increase awareness of the relationship between health and beauty may be recommended. Note that information on recommended skin care, makeup, and beauty methods may be determined in advance for each psychological well-being group (e.g., a group with low psychological well-being, a group with high psychological well-being, and a group with intermediate psychological well-being (between low and high)).

[0076] <<Evaluation and recommendation of awareness of at least one of health, beauty, skin care, and makeup based on psychological well-being>> The following describes evaluation and recommendation of awareness of at least one of health regimens, beauty regimens, skin care, and makeup based on psychological well-being. First, information on the psychological well-being of the subject 20 is obtained. Next, based on the information on the psychological well-being of the subject 20, the awareness of the subject 20 of at least one of health regimens, beauty regimens, skin care, and makeup is evaluated. Next, based on the results of the evaluation of awareness of at least one of health regimens, beauty regimens, skin care, and makeup, one or more of skin care, makeup, and beauty regimens that will change the awareness of the subject 20 of at least one of health regimens, beauty regimens, skin care, and makeup are recommended.

[0077] <<Evaluation and recommendation of psychological well-being based on physiological skin data>> The following describes the evaluation and recommendation of psychological well-being based on physiological skin data. First, physiological skin data of the subject 20 is obtained. Next, the psychological well-being of the subject 20 is evaluated based on the physiological skin data of the subject 20. Next, based on the results of the psychological well-being evaluation, one or more of skin care, makeup, and beauty methods that change the physiological skin data of the subject 20 are recommended.

[0078] [evaluation] For example, the physiological data of the skin of subject 20 can be quantified and the subject can be classified into psychological well-being groups corresponding to the numerical values ​​of the physiological data of the skin (e.g., a group with low psychological well-being, a group with high psychological well-being, or a group with intermediate psychological well-being (between low and high)).

[0079] Specifically, the higher the degree of skin firmness (e.g., facial (e.g., cheek) skin firmness), the higher the psychological well-being (i.e., subject 20 is in a good psychological state), and the lower the degree of skin firmness, the lower the psychological well-being (i.e., subject 20 is in a poor psychological state). Note that the degree of skin firmness may be the sum of the degree of "net elasticity," the degree of "viscoelasticity," and the degree of negative "skin softness (ease of skin stretching)," or any one or two of the degree of "net elasticity," the degree of "viscoelasticity," and the degree of negative "skin softness (ease of skin stretching)."

[0080] Specifically, the higher the degree of yellowness of the skin (for example, the yellowness of the skin on the face (e.g., cheeks) or the yellowness of the skin on the arms), the higher the psychological well-being is evaluated (i.e., the subject 20 is in a good psychological state), and the lower the degree of yellowness of the skin, the lower the psychological well-being is evaluated (i.e., the subject 20 is not in a good psychological state). Note that the degree of yellowness of the skin may be the sum of the degree of "chroma", the degree of "melanin", and the degree of "yellowness value (b*)", or any one or two of the degree of "chroma", the degree of "melanin", and the degree of "yellowness value (b*)" may be used.

[0081] Specifically, the lower the degree of skin roughness (e.g., the roughness of the skin on the face (e.g., cheeks)), the higher the psychological well-being (i.e., subject 20 is in a good psychological state), and the higher the degree of skin roughness, the lower the psychological well-being (i.e., subject 20 is in a poor psychological state).

[0082] [Recommended] For example, one or more of skin care, makeup, beauty treatments, and supplements that increase the firmness of the skin may be recommended. Also, for example, one or more of skin care, makeup, and beauty treatments that increase the yellowness of the skin may be recommended. Also, for example, one or more of skin care, makeup, and beauty treatments that reduce the roughness of the skin may be recommended. Note that information on recommended skin care, makeup, and beauty treatments may be determined in advance for each psychological well-being group (e.g., a group with low psychological well-being, a group with high psychological well-being, and a group with intermediate psychological well-being (between low and high)).

[0083] <<Evaluation and recommendation of physiological skin data based on psychological well-being>> The evaluation and recommendation of physiological skin data based on psychological well-being will be described.
