Description

[Technical Field]

[0001] The present invention relates to a skin cosmetic, specifically to a skin cosmetic that provides a moisturizing feeling to the skin after application, is not sticky, and has elasticity and a lifting effect. [Background technology]

[0002] Conventionally, skin care has a role to play in providing and maintaining a moisturizing feeling to the skin, and skin cosmetics containing amino acids have been known to achieve this. For example, Patent Documents 1 and 2 disclose that amino acids are incorporated into skin cosmetics to improve the moisturizing feeling that retains water in the stratum corneum.

[0003] On the other hand, in recent years, skin care products are being sought that go beyond the basic function of providing a moisturizing feeling to also provide additional benefits. Among these, active seniors, or active people, prefer skin care products that improve skin elasticity and have a lifting effect.

[0004] Although skin cosmetics containing amino acids improve moisturizing feeling, there have been no reports of their elasticity or lifting effect. Therefore, there is a demand for skin cosmetics containing amino acids that improve moisturizing feeling and also have skin elasticity and lifting effect. [Prior art documents] [Patent documents]

[0021] After washing their faces as usual, five expert panel members took 3 mL of the skin cosmetic of the Example or Comparative Example in their hands, applied it to their faces, and allowed it to blend in for evaluation.

[0022] [1] Skin moisturizing evaluation test (Test Method) After applying the skin cosmetic of the Examples or Comparative Examples, the skin was evaluated according to the following evaluation criteria, and the average value was taken as the test result. <Evaluation criteria> 5: After applying, my skin felt very moisturized. 4: I felt a slight moisturizing sensation on my skin after applying it. 3: After application, I felt a slight moisturizing sensation on my skin. 2: I didn't feel much moisturization on my skin after applying it. 1: I didn't feel any moisturizing sensation on my skin after applying it. <Judgment criteria> ◎: Average value is 4.0 or more ○: Average value is 3.0 or more and less than 4.0 △: Average value is 2.0 or more and less than 3.0 ×: Average value is less than 2.0

[0023] [2] Evaluation test for non-stickiness on skin (Test Method) After applying the skin cosmetic of the Examples or Comparative Examples, the skin was evaluated according to the following evaluation criteria, and the average value was taken as the test result. <Evaluation criteria> 5: I felt that there was very little stickiness on my skin after it was absorbed. 4: I felt that it was not sticky on my skin after it was applied. 3: After application, there was a very slight feeling of non-stickiness on the skin. 2: I didn't feel much stickiness on my skin after applying it. 1: I didn't feel any stickiness on my skin after applying it. <Judgment criteria> ◎: Average value is 4.0 or more ○: Average value is 3.0 or more and less than 4.0 △: Average value is 2.0 or more and less than 3.0 ×: Average value is less than 2.0

[0024] [3] Skin elasticity evaluation test (Test Method) Five volunteers were asked to wash their faces and then rest for 10 minutes in a room at 22°C and 50% RH. Then, a Cutometer (MPA580, Courage+Khazaka) was used to measure skin elasticity R7. before Then, 1.0 mL of the skin cosmetic of the Example or Comparative Example was applied to half of the face, and after 10 minutes of rest, the skin elasticity R7 was measured again using the Cutometer. after The percentage change in skin elasticity before and after application was calculated using the formula below, and the average value of the five subjects was used to classify the results into the following scores. <Skin elasticity evaluation score> ΔR7=(R7 after -R7 before ) x 100 <Judgment criteria> ◎: The average score of 5 people was 105% or higher. ○: The average score of the 5 participants was 95% or more but less than 105%. ×: The average score of 5 people was less than 95%.

[0025] [4] Skin lifting effect evaluation test (Test Method) <Evaluation criteria> 5: I felt a strong lifting effect on my skin after applying it. 4: I felt a slight lifting effect on my skin after applying it. 3: I felt a slight lifting effect on my skin after applying it. 2: I didn't feel much of a lifting effect on my skin after applying it. 1: I didn't feel any lifting effect on my skin after applying it. <Judgment criteria> ◎: Average value is 4.0 or more ○: Average value is 3.0 or more and less than 4.0 △: Average value is 2.0 or more and less than 3.0 ×: Average value is less than 2.0
