Abstract

In order to verify whether the serum using the medicinal plant Coptis japonica is effective in anti-aging of the skin, the improvement rate was analyzed by measuring the skin elasticity and radiance of the subjects, and the satisfaction was evaluated through a questionnaire. Twenty-two female subjects were given a serum containing 3% Coptis Japonica extract on one cheek for 4 weeks, and the test site was measured, and the skin elasticity increased by 5.73% from 0.8505 ± 0.0395 R2 (mm) before use to 0.8993 ± 0.0234 R2 (mm) after 4 weeks. Skin glow increased by 4.74% from 55.94 ± 5.49 (a.u.) to 58.59 ± 4.66 (a.u.), and the probability of significance was p<0.001, indicating a significant increase in the improvement rate of both items. It was found that all subjects were 100% satisfied with the improvement of elasticity and 95.5% satisfied with the improvement of radiance, and no skin abnormalities were found during the trial period. These results are expected to be used as basic data for future research and product development of anti-aging functional cosmetics using Coptis Japonica extract.

약용식물 황련(Coptis Japonica)을 이용한 세럼이 피부 항노화에 효과적인지 검증하기 위해 피험자의 피부 탄력과 윤기를 측정하여 개선율을 분석하고 설문을 통해 만족도를 평가하였다. 22명의 여성 피험자 한쪽 뺨 부위에 황련 추출물을 3% 배합한 세럼을 4주 동안 사용하게 한 후 시험 부위를 측정한 결과 피부 탄력은 사용 전 0.8505 ± 0.0395 R2(mm)에서 4주 후 0.8993 ± 0.0234 R2(mm)로 5.73% 증가하였다. 피부 윤기는 55.94 ± 5.49 (a.u.)에서 58.59 ± 4.66 (a.u.)로 4.74% 증가하였으며 유의확률이 모두 p<0.001로 나타나 두 항목 모두 개선율이 유의하게 증가한 것으로 나타났다. 설문에 의한 탄력 개선은 피험자 모두 100% 만족하는 것으로 나타났고 윤기 개선은 95.5% 만족하는 것으로 나타났으며 시험 기간 내 피부 이상은 확인되지 않았다. 이와 같은 결과는 향후 황련 추출물을 이용한 항노화 기능성 화장품의 연구와 제품 개발에 본 연구가 기초 자료로 활용될 것으로 사료된다.
