다국어 초록 (Multilingual 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.
