초록

Hyaluronic acid is natural polysaccharide existing around skin or cartilage, and is known as a moisturizing factor. It is expected that hyaluronic acid cosmetics market will continue to grow in the future, as its use and demand increases, like medical supplies and health food besides cosmetics containing hyaluronic acid. However, There are few present studies on content in cosmetics containing hyaluronic acid. The purpose of this study was to evaluate satisfaction and examine what effect was produced on sebum and moisture in skin after applying to cosmetics the hyaluronic acid helpful in maintaining moisture in skin at 5%, 20% and 50% concentration. For 71 days, a clinical trial in a total 39 persons living in the national capital region was carried out. And sebum and moisture was measured through skin diagnosis system A-ONE TAB before trial and each day when clinical trial was conducted for hyaluronic acid content group. Besides, this study was to examine subjects' general characteristics, eating habits, and living habits, and satisfaction after the clinical trial. This study analyzed a difference according to the time to measure the skin condition among hyaluronic acid content groups by utilizing statistical package program SPSS v. 21.0 through data coding and data cleaning process. There was no statistically significant difference in hyaluronic acid content according to any of demographic characteristics, eating habits and living habits among groups (p>.05). With regard to hyaluronic acid content, there was no statistically significant difference in moisture and sebum prior to clinical trial in T zone and U zone among groups (p>.05). A change of moisture in T zone among groups according to hyaluronic acid content showed statistically significant difference in the 2nd week (F =3.636, p<.05). And the highest level was shown in 50%(44.15±2.672), being followed by 20%(43.15±2.340), and 5%(41.62±2.219). Accordingly, it was shown that, as hyaluronic acid content relatively increased, the moisture in T zone increased. In the results of analyzing the change of moisture in U zone, the change of sebum in T zone and U zone by group according to hyaluronic acid content, no statistically significant difference was shown in sebum level of T zone by group(p>.05). For analyzing the subjective satisfaction after clinical trial among groups according to hyaluronic acid content, satisfaction score was the highest in 'skin moistness' (4.38±0.650) for 5% group, 'skin moistness' (4.69±0.480) for 20% group and 'skin texture smoothness' (4.54±0.519) for 50% group. And no statistically significant difference was shown in each subjective satisfaction by group according to hyaluronic acid content(p>.05). It was thought that the results of skin condition and subjective satisfaction survey according to hyaluronic acid content would be baseline data for developing cosmetics containing the hyaluronic acid and marketing a skin moisturizer.
