[0032] BRIEF DESCRIPTION OF DRAWINGS

[0033] Figure 1 shows an example of the cosmetic method according to the present invention to apply a cosmetic composition onto the face.

[0034] Figure 2 shows an example of the conventional cosmetic method to apply a cosmetic composition onto the face.

[0035] BEST MODE FOR CARRYING OUT THE INVENTION

[0036] After diligent research, the inventors have discovered a new cosmetic method for applying a cosmetic composition onto the face which can reduce friction and provide comfortable feeling to use.

[0037] Thus, one aspect of the present invention is a cosmetic method for applying a cosmetic composition onto the face, comprising the steps of:

[0038] (1) providing a cosmetic composition on the palm of a hand or the palms of hands;

[0039] (2) spreading the cosmetic composition on the palms of hands;

[0040] (3) tapping the face with the palms of hands; and

[0041] (4) sliding the palms of hands across the face. The cosmetic method according to the present invention can reduce friction during the application of the cosmetic composition onto the face, and therefore, the cosmetic method according to the present invention can reduce uncomfortable feeling during use such as a dragging sensation. Thus, the cosmetic method according to the present invention can provide comfortable feeling to use.

[0042] The reduction of friction during the application of the cosmetic composition by the cosmetic method according to the present invention can be attributed to reduced pressure during the application, during the steps (3) and (4), in particular the step (4), of the cosmetic method according to the present invention.

[0043] In the step (4) of the cosmetic method according to the present invention, the palms of hands are used to apply the cosmetic composition onto the face. The palms of hands have a larger surface area than the fingers. Therefore, the pressure (per unit area) applied to the face can be reduced by the use of the palms of hands as compared to the use of the fingers, even if the same power is used for the application.

[0044] In addition, in the step (3) of the cosmetic method according to the present invention, a part of the cosmetic composition can be applied onto the face before the step (4), by tapping the face with the palms of hands having the cosmetic composition on the surface of the palms of hands. Thus, it is not necessary in the step (4) to spread a relatively large amount of the cosmetic composition on the face. Also, a part of the cosmetic composition which has been applied onto the face by tapping in the step (3) can function as a smoothing agent to make the sliding in the step (4) smooth. These can also contribute to reduce the pressure applied to the face during the application of the cosmetic composition in the step (4).

[0045] In order to reduce the pressure applied to the face in the step (3) and / or the step (4) of the cosmetic method according to the present invention, it is preferable not to use fingers. In other words, it is preferable to use only the palms of hands in the step (3) and / or the step (4) of the cosmetic method according to the present invention. Fingers, in particular, fingertips, have a much smaller surface area than the palms of hands. Thus, if the cosmetic composition is applied onto the face in the step (3) and / or the step (4) using fingers, in particular, the fingertips, the pressure (per unit area) applied to the face can be increased, as compared to using the palms of hands. Therefore, friction on the face can be increased, and this can provide uncomfortable feeling to use.

[0046] As the cosmetic method according to the present invention can reduce friction, the cosmetic method according to the present invention can be preferably used for cosmetic treatments of sensitive skins. Thus, the cosmetic method according to the present invention can be advantageously used for the facial skin including sensitive skin.

[0047] Hereinafter, the cosmetic method according to the present invention and the like will be explained in a more detailed manner.

[0048] [Cosmetic Method of Present Invention]

[0049] The cosmetic method, or cosmetic process, according to the present invention is a method or process for beautifying the face, and is not a medicinal method or process for therapeutically treating the face. The cosmetic method according to the present invention for applying a cosmetic composition onto the face comprises the steps of:

[0050] (1) providing a cosmetic composition on the palm of a hand or the palms of hands;

[0051] (2) spreading the cosmetic composition on the palms of hands;

[0052] (3) tapping the face with the palms of hands; and

[0053] (4) sliding the palms of hands across the face.

[0054] The cosmetic method according to the present invention may be characterized by using the palms of hands to apply a cosmetic composition onto the face.

[0055] Each step comprised in the cosmetic method according to the present invention will be described below with Fig. 1.

[0056] Fig. 1 shows an example of the cosmetic method according to the present invention to apply a cosmetic composition onto the face. Parts (1) to part (4) in Fig. 1 correspond to the steps (1) to (4), respectively, in the cosmetic method according to the present invention. Part (5) in Fig. 1 corresponds to one of the optional steps for the cosmetic method according to the present invention.

[0057] (Step 1)

[0058] The step (1) in the cosmetic method according to the present invention involves providing a cosmetic composition on the palm of a hand or the palms of hands.

[0059] Thus, in the step (1), a cosmetic composition is provided on one of the palms of hands or both of the palms of hands.

[0060] There is no limitation regarding the amount of the cosmetic composition to be provided in the step (1) of the cosmetic method according to the present invention.

[0061] It may be preferable that the amount of the cosmetic composition to be provided on the palm of hand or the palms of hands is 0.3 g or more, more preferably 0.4 g or more, and even more preferably 0.5 g or more. An amount of 0.3 g or more of a cosmetic composition can provide a cosmetic film on the face with a sufficient thickness of the cosmetic composition.

[0062] It may be preferable that the amount of the cosmetic composition to be provided on the palm of hand or the palms of hands is 0.8 g or less, more preferably 0.7 g or less, and even more preferably 0.6 g or less.

[0063] Thus, it may be preferable that the amount of the cosmetic composition provided in the step (1) of the cosmetic method according to the present invention is from 0.3 g to 0.8 g, more preferably from 0.4 g to 0.7 g, and even more preferably from 0.5 g to 0.6 g.

[0064] Part (1) of Fig. 1 shows an example of providing the cosmetic composition on the palm of a hand. In the part (1) of Fig. 1 , a cosmetic composition is provided at the center of the palm of a hand.

[0065] In the step (1) of the cosmetic method according to the present invention, the cosmetic composition may be provided onto the palm of a hand or the palms of hands, in the form of a ball such as a pearl ball or in the form of a line such as a linear or spiral line, in order to provide 0.3 g or more, preferably 0.4 g or more, and more preferably 0.5 g or more, of the cosmetic composition.

[0066] The cosmetic composition may be filled, for example, in a container, such as a tube, with a nozzle, and the cosmetic composition may be discharged from the nozzle, by pressing.

[0067] The container may not be moved to discharge the cosmetic composition in the form of a ball such as a pearl ball, or may be moved to discharge the cosmetic composition in the form of a line such as a linear or spiral line.

[0068] (Step 2)

[0069] The step (2) in the cosmetic method according to the present invention involves spreading the cosmetic composition on the palms of hands.

[0070] Thus, in the step (2), the cosmetic composition is spread on the palms of hands.

[0071] The step (2) can be performed after the step (1).

[0072] There is no limitation regarding how to spread the cosmetic composition on the palms of hands in the step (2) of the cosmetic method according to the present invention.

[0073] In one embodiment, in the step (2), a user can contact the palms of hands with each other through a circular movement. In this embodiment, for example, the user can make the palms, one of which the cosmetic composition has been provided on by the step (1), of hands contact each other, and rotate the palms of hands in different directions to spread the cosmetic composition on the surface of the palms of hands. The number of circular movement or rotation is not limited, but may be sufficient to perform several times such as twice and three times.

[0074] The part (2) of Fig. 1 shows an example of spreading the cosmetic composition on the palms of hands. In the part (2) of Fig. 1, two palms of both hands in contact with each other are rotated in different directions to spread the cosmetic composition on the surfaces of the palms of both hands.

[0075] It is preferable that no fingers are used for the step (2) of the cosmetic method according to the present invention. In other words, it is preferable that the spreading in the step (2) of the cosmetic method according to the present invention is performed using only the palms of hands. Thus, it is preferable that the cosmetic composition is not spread on the fmger(s) in the step (2) of the cosmetic method according to the present invention.

[0076] It is also preferable to apply minimal pressure in the step (2) of the cosmetic method according to the present invention when contacting the palms of hands with each other.

[0077] It is also preferable to gently perform the circular movement or rotation in the step (2) of the cosmetic method according to the present invention.

[0078] It is also preferable to spread the cosmetic composition on the palms of hands, in the step (2) of the cosmetic method according to the present invention, such that the cosmetic composition is spread substantially uniformly on the entire surfaces of the palms of both hands. As a result of step (2) of the cosmetic method according to the present invention, the cosmetic composition can be distributed across the surface of the palms of hands.

[0079] (Step 3)

[0080] Step (3) in the cosmetic method according to the present invention involves tapping the face with the palms of hands.

[0081] Thus, in the step (3), at least a part of the cosmetic composition on the palms of hands can be applied onto the face.

[0082] The step (3) can be performed after the step (2).

[0083] In one embodiment, in the step (3), a user can tap the face with the palms of hands several times, in order to apply to the face a substantial amount of the cosmetic composition from the palms of hands on which the cosmetic composition has been spread by the step (2). In other words, the tapping in the step (3) can be repeated.

[0084] There is no limitation regarding how to tap the face with the palms of hands. The number of tapping is not limited, but may be sufficient to perform several times such as eight or nine times.

[0085] The part (3) of Fig. 1 shows an example of tapping the face with the palms of hands. In the part (3) of Fig. 1, the cheeks of the face are being tapped with the palms of hands. In the part (3) of Fig. 1, tapping the cheeks can be repeated several times.

[0086] In the example shown in the part (3) of Fig. 1, a user may start tapping the cheeks of the face, and move the tapping zone from the cheeks to, for example, the forehead, chin or nose. It is preferable to perform the tapping such that the tapping action can cover or wrap the entire of the face. In other words, it is preferable that the palms of the hands tap over the face.

[0087] Thus, it is preferable to move the tapping zone from, for example, the cheeks to the forehead, chin or nose.

[0088] It is preferable that no fingers are used for the step (3) of the cosmetic method according to the present invention. In other words, it is preferable that the tapping in the step (3) of the cosmetic method according to the present invention is performed using only the palms of hands. Thus, it is preferable that the tapping in the step (3) of the cosmetic method according to the present invention is not performed using finger(s).

[0089] It is also preferable to apply minimal pressure in the step (3) of the cosmetic method according to the present invention when tapping the face with the palms of hands.

[0090] As a result of step (3) of the cosmetic method according to the present invention, at least a part of the cosmetic composition on the palms of hands can be applied on the surface of the face. The rest of the cosmetic composition can remain on the palms of hands.

[0091] Furthermore, as a result of step (3) of the cosmetic method according to the present invention, using the palms of hands, the cosmetic composition can be applied in the next step (4) with less friction or reduced pressure as compared to using fingers. (Step 4)

[0092] Step (4) in the cosmetic method according to the present invention involves sliding the palms of hands across the face.

[0093] Thus, in the step (4), the cosmetic composition remaining on the palms of hands after the step (3) can be applied onto the face.

[0094] The step (4) can be performed after the step (3).

[0095] It is preferable that the palms of hands are slid from the center to the edges of the face. In other words, it is preferable that the palms of hands are slid from the center of the face and out toward the peripheries of the face.

[0096] In one embodiment, in the step (4), a user can slide the palms of hands several times across the face, wherein the cosmetic composition remains on the palms of hands after the step (3). In other words, the sliding in the step (4) of the cosmetic method according to the present invention can be repeated.

[0097] There is no limitation regarding how to slide the palms of hands across the face. The number of sliding is not limited, but may be sufficient to perform several times such as five or six times.

[0098] The part (4) of Fig. 1 shows an example of sliding the palms of hands across the face. In the part (4) of Fig. 1, the palms of hands are slid on the cheeks of the face. In the part (4) of Fig. 1, sliding the palms of hands on the cheeks can be repeated several times.

[0099] In the example shown in the part (4) of Fig. 1, a user may start sliding the palms of hands on the cheeks of the face, and move the sliding zone from the cheeks to, for example, the forehead, chin or nose. It is preferable to perform the sliding such that the sliding action can cover or wrap the entire of the face. Thus, it is preferable to move the sliding zone from, for example, the cheeks to the forehead, chin or nose.

[0100] It is preferable that no fingers are used for the step (4) of the cosmetic method according to the present invention. In other words, it is preferable that the sliding in the step (4) of the cosmetic method according to the present invention is performed using only the palms of hands. Thus, it is preferable that the sliding in the step (4) of the cosmetic method according to the present invention is not performed using fmger(s).

[0101] It is also preferable to apply minimal pressure in the step (4) of the cosmetic method according to the present invention when sliding the palms of hands across the face.

[0102] It is also preferable that the pressure applied to the face by the step (4) of the cosmetic method according to the present invention is less than 0.60N, preferably less than 0.56N, and more preferably less than 0.52N. The pressure when tapping can be measured by, for example, a HAPTIC Force Plate (TF-2020, Tec Gihan Co., Ltd.).

[0103] As a result of step (4) of the cosmetic method according to the present invention, the cosmetic composition remaining on the palms of hands after the step (3) can be applied on the surface of the face. A part of the cosmetic composition may still remain on the palms of hands.

[0104] Further, as a result of the step (4) of the cosmetic method according to the present invention, the cosmetic composition can be applied evenly or homogeneously onto the face.

[0105] Furthermore, as a result of step (4) of the cosmetic method according to the present invention, by using the palms of hands, the cosmetic composition can be applied with less friction or reduced pressure as compared to using fingers.

[0106] Since a part of the cosmetic composition has already been applied onto the face in the step (3), it is not necessary in the step (4) of the cosmetic method according to the present invention to spread a relatively large amount of the cosmetic composition on the face. Also, a part of the cosmetic composition which has been applied onto the face by tapping in the step (3) can function as a smoothing agent to make the sliding in the step (4) smooth. These can also contribute to reduce the pressure applied to the face during the application of the cosmetic composition in the step (4) of the cosmetic method according to the present invention.

[0107] (Additional Step)

[0108] The cosmetic method according to the present invention may further comprise at least one additional step.

[0109] (Step 5)

[0110] The cosmetic method according to the present invention may further comprise step (5) of pressing the face with at least the palms of hands.

[0111] In the step (5) of the cosmetic method according to the present invention, the face is pressed with, at least, the palms of hands across the face. It is possible to use a finger or fingers of hands as well to press the face.

[0112] The step (5) can be performed after the step (4).

[0113] In one embodiment, a user can press the face with at least the palms of hands several times, wherein the cosmetic composition may still remain on the palms of hands after the step (5). In other words, the pressing in the step (5) can be repeated.

[0114] There is no limitation regarding how to press the face with at least the palms of hands. The number of pressing is not limited, but may be sufficient to perform several times such as eight or nine times.

[0115] The part (5) of Fig. 1 shows an example of pressing the face with hands using not only the palms of hands but also the fingers. In the part (5) of Fig. 1, the forehead and one of the cheeks of a user are pressed by the whole hands. In the part (5) of Fig. 1, pressing the forehead and one of the cheeks can be repeated several times.

[0116] In the example shown in the part (5) of Fig. 1, a user may start pressing the forehead and cheeks of the face, and move the pressing zone from the forehead and cheeks to, for example, the chin or nose. It is preferable to perform pressing such that the pressing action cover or wrap the entire of the face. Thus, it is preferable to move the pressing zone from, for example, the forehead and cheeks to the chin or nose.

[0117] It is also preferable to apply minimal pressure in the step (5) of the cosmetic method according to the present invention when pressing the face with at least the palms of hands.

[0118] As a result of step (5), the absorption of the ingredients in the cosmetic composition by the facial skin can be enhanced. Further, an even distribution of the cosmetic composition on the facial skin can also be enhanced. Furthermore, the cosmetic film of the cosmetic composition can be adhered well to the face.

[0119] (Step 6)

[0120] The cosmetic method according to the present invention may further comprise step (6) of applying the cosmetic composition on the palms of hands to the body except for the face.

[0121] The step (6) is not shown in Fig. 1.

[0122] In the step (6) of the cosmetic method according to the present invention, the cosmetic composition which still remains on the palms of hands is applied to the body except for the face. It is possible to use a finger or fingers as well to apply the cosmetic composition onto the body except for the face.

[0123] The step (6) can be performed after the step (5).

[0124] In one embodiment, a user can apply the cosmetic composition which still remains on the palms of hands to, for example, the backs of hands, elbows, and the like.

[0125] There is no limitation regarding how to perform the step (6).

[0126] As a result of step (6), the cosmetic composition which still remains on the palms of hands can be effectively used for cosmetic treatments of skin which may need the cosmetic composition.

[0127] [Conventional Cosmetic Method]

[0128] For the purpose of the comparison between the cosmetic method according to the present invention and the conventional cosmetic method, the conventional cosmetic method is briefly explained below.

[0129] Fig. 2 shows an example of the conventional cosmetic method to apply a cosmetic composition onto the face.

[0130] In the part (1) of Fig. 2, a cosmetic composition is taken out from a container thereof, such as a tube, with a nozzle, by being discharged from the nozzle, as shown in in Fig. 2, on the back of hand.

[0131] In the part (2) of Fig, 2, the cosmetic composition is applied with at least one finger at five points of the face, i.e., the center of the forehead, the cheeks, the center of the nose, and the center of the chin. In the part (3) of Fig. 2, the cosmetic composition on the five points is spread from the center to the edges of the face with hands. The palms and fingers may be used.

[0132] In the part (4) of Fig. 2, fingertips may be used to apply the cosmetic composition to the three-dimensional shapes on the face, such as nostril and eyelids.

[0133] In the part (5) of Fig. 2, pressing is performed using at least the palms of hands.

[0134] The conventional cosmetic method shown in Fig. 2 can cause more friction because fingers are used in the parts of (3) and / or (4).

[0135] Fingers, in particular, the fingertips, have a much smaller surface area than the palms of hands. Thus, if the cosmetic composition is applied onto the face in the parts of (3) and / or (4) in Fig. 2 using fingers, in particular, the fingertips, the pressure (per unit area) applied to the face can be increased, as compared to using the palms of hands. In addition, fingers, in particular fingertips, have more uneven surfaces as compared to palms of hands. Therefore, friction on the face can be increased, and this can provide uncomfortable feeling to use.

[0136] On the other hand, the cosmetic method according to the present invention uses the palms of hands. The palms of hands have a larger surface area than the fingers. Therefore, the cosmetic method according to the present invention can reduce the pressure (per unit area) applied to the face by using the palms of hands as compared to using the fingers. Therefore, friction on the face can be reduced, and this can provide comfortable feeling to use.

[0137] (Cosmetic Composition)

[0138] The cosmetic composition to be used for the cosmetic method according to the present invention is not limited.

[0139] It is preferable the cosmetic composition is a cosmetic composition for skin, more preferably for caring for skin, and even more preferably a cosmetic composition for caring for facial skin.

[0191] In one embodiment, the (d) active ingredient for sensitive skin, may be: (el) at least one nonphotosynthetic filamentous bacterium extract.

[0192] The expression “non-photosynthetic filamentous bacteria extract” is understood to mean equally well the supernatant from culturing the bacteria, the biomass obtained after culturing the bacteria or alternatively the extracts from the biomass obtained by treatment of this biomass.

[0193] The bacterial extracts may be prepared from non-photosynthetic filamentous bacteria as defined according to the classification of Bergey's Manual of Systematic Bacteriology (vol. 3, sections 22 and 23, 9th edition, 1989), among which may be mentioned the bacteria belonging to the order of the Beggiatoales and more particularly the bacteria belonging to the genera Beggiatoa, Vitreoscilla, Flexithrix or Leucothrix.

[0201] In order to prepare the extract, the bacteria can be cultured according to methods known to the person skilled in the art and they can then be separated from the biomass obtained, for example by filtration, centrifuging, coagulation and / or lyophilization. It is possible in particular to prepare the extracts which can be used, according to the process described in WO 94 / 02158.

[0202] Thus, after culturing, the bacteria are concentrated by centrifuging. The biomass obtained is autoclaved. This biomass can be lyophilized in order to form what is known as the lyophilized extract. Any lyophilization method known to the person skilled in the art can be used to prepare this extract. The supernatant fraction from this biomass can also be filtered in a sterile receptacle in order to remove the suspended particles. The extract is thus obtained which is otherwise known in the text as aqueous extract.

[0241] Example 1 and Comparative Example 1

[0242] [Example 1] 105 participants (Japanese women in ages of 20-49) performed the cosmetic method according to Example 1 during 14 days.

[0243] A tube having a nozzle and including a skin cosmetic product (La Roche-Posay Cicaplast baume B5) was pressed to discharge the skin cosmetic product from the nozzle, onto the skin of the palm of a hand of each panelist (cf. the part (1) of Fig. 1). The amount of the skin cosmetic product was around 0.3 g.

[0244] Then, the above palm of the hand with the skin cosmetic product was gently pressed with the palm of the other hand, then the palms of both hands were rotated in opposite directions, while being contacted with each other, in order to spread the skin cosmetic product on the surface of the palms of both hands (cf. the part (2) of Fig. 1).

[0245] Next, the facial skin of each panelist was tapped by the palms of both hands, without using fingers. The tapping was repeated to envelope or wrap the face (cf. the part (3) of Fig. 1).

[0246] Next, the palms of both hands were applied to the center of the face, and were slid from the center to the edges of the face, in order to spread the skin cosmetic product on the face. The fingers were not used to spread the skin cosmetic product on the face (cf. the part (4) of Fig. 1).

[0247] Lastly, the face was pressed with the palms and / or fingers of both hands in order to adhere well the film of the skin cosmetic product onto the facial skin and / or to confirm the evenness of the appearance of the face (cf. the part (5) of Fig. 1).

[0248] [Comparative Example 1]

[0249] 107 participants (Japanese women between ages 20-49) performed the cosmetic method according to Comparative Example 1 during 14 days.

[0250] A tube having a nozzle and including a skin cosmetic product (La Roche-Posay Cicaplast baume B5) was pressed to discharge the skin cosmetic product from the nozzle, onto the back of a hand of each panelist (cf. the part (1 ) of Fig. 2). The amount of the skin cosmetic product was around 0.3 g.

[0251] Next, the skin cosmetic product was divided and taken by the fingertips of the panelist to place the skin cosmetic product at five spots, i.e., the center of the forehead, both of the cheeks, the center of the nose, and the center of the chin, on the face of each panelist (cf. the part (2) of Fig. 2).

[0252] Next, the skin cosmetic product present at the five spots was spread over the face with fingers, from the center to the edges of the face (cf. the part (3) of Fig. 2). For three-dimensional shapes on the face, such as nostrils and eyelids, fingertips were used to spread the skin cosmetic product (cf. the part (4) of Fig. 2).

[0253] Lastly, the face was pressed with the palms and / or fingers of the hands in order to adhere well the film of the skin cosmetic product onto the facial skin and / or to confirm the evenness of the appearance of the face (cf. the part (5) of Fig. 2). [Evaluations]

[0254] (Participant Preference Assessment)

[0255] The participants who performed the cosmetic methods according to Example 1 and Comparative Example 1 evaluated the feeling during use (e.g., this application gesture is gentle on the skin) provided by the skin cosmetic product, and scored them from 1 (Disagree) to 5 (Agree). The results of the evaluation were statistically analyzed to find any significant difference.

[0256] It was found that the cosmetic method according to Example 1 provided statistically significant better feeling to use than the cosmetic method according to Comparative Example 1.

[0257] (Pressure Evaluation)

[0258] The pressure applied to the skin when applying the skin cosmetic product in the cosmetic methods according to Example 1 and Comparative Example 1 was imitated and measured.

[0259] <Under Imitation of Example 1>

[0260] The forearm of a volunteer was placed on a HAPTIC Force Plate (TF-2020, Tech Gihan Co., Ltd.) as a pressure sensor.

[0261] A tube having a nozzle and including a skin cosmetic product (La Roche-Posay Cicaplast baume B5) was pressed to discharge the skin cosmetic product from the tube via the nozzle into a bottle. Then, the discharged skin cosmetic product was placed on the skin of the palm of a hand of an expert (well-trained esthetician) by a pipette. The amount of the skin cosmetic product was 0.3 g.

[0262] Then, the above palm of the hand with the skin cosmetic product was gently pressed with the palm of the other hand, then the palms of both hands were rotated in opposite directions, while being contacted with each other, in order to spread the skin cosmetic product on the surface of the palms of both hands.

[0263] One of the forearms of the volunteer was tapped by the palm of the dominant hand of the expert without using fingers. The tapping was repeated 5 times along the direction from the elbow to the wrist of the volunteer.

[0264] Next, the palm of the dominant hand of the expert was applied to the forearm near the elbow of the volunteer, and was slid along the direction from the elbow to the wrist, in order to spread the skin cosmetic product on the forearm. Fingers were not used to spread the skin cosmetic product on the forearm.

[0265] The sliding speed of the palm was controlled to be 53.5 cm / sec using a metronome. The pressure applied to the forearm during spreading was measured by the HAPTIC Force Plate. In total, 40 spreading data was taken on the volunteer’s forearm and the results were averaged.

[0266] The average pressure was 0.51 N. <Under Imitation of Comparative Example 1>

[0267] The forearm of a volunteer was placed on a HAPTIC Force Plate (TF-2020, Tech Gihan Co., Ltd.) as a pressure sensor.

[0268] A tube having a nozzle and including a skin cosmetic product (La Roche-Posay Cicaplast baume B5) was pressed to discharge the skin cosmetic product from the tube via the nozzle into a bottle. Then, the discharged skin cosmetic product was placed on the skin of the palm of a hand of an expert (well-trained esthetician) by a pipette. The amount of the skin cosmetic product was 0.15 g.

[0269] Next, the skin cosmetic product was divided and placed the skin cosmetic product at two spots (0.15 g each) on near the elbow of one of the forearms of the volunteer.

[0270] Next, the palm and fingers of the dominant hand of the expert were applied to the forearm near the elbow of the volunteer, and were slid along the direction from the elbow to the wrist, in order to spread the skin cosmetic product on the forearm. The palms and fingers were used to spread the skin cosmetic product on the forearm.

[0271] The sliding speed of the palm and fingers was controlled to be 53.5 cm / sec by using a metronome. The pressure applied during spreading was measured by the HAPTIC Force Plate. In total, 40 spreading data was taken on the volunteer’s forearm and the results were averaged.

[0272] The average pressure was 0.64 N.

[0273] <Results>

[0274] The application pressure provided by the cosmetic method according to Example 1 was 20% lower than that provided by the cosmetic method according to Comparative Example 1.

[0275] It is clear that a lower application pressure can reduce skin friction, and improve spreadability and texture. Thus, the cosmetic process according to Example 1 can reduce skin friction, and improve spreadability and texture, as compared to the cosmetic method according to Comparative Example 1.
