This study is designed to observe human consuming effect of a beauty drink powder and combined use with a cosmetic apparatus. It is a randomized, double-blind, and placebo-control study. The target enrollment of subjects is 160 and 4 arms are included, a placebo control, drink powder alone, cosmetic apparatus alone, and drink powder plus cosmetic apparatus. Effects on skin dullness, skin tone unevenness, skin dryness, skin elasticity, wrinkle and fine line are evaluated. Both objective and subjective methods are used for efficacy evaluation. Data are collected at baseline, week 4, week 8, and week 12 after treatment.
In this study, objective parameters are measured by the instruments as following: VisioScan VC20 is used for skin roughness and wrinkle assessment, chromameter CR-400 is used to assess skin color, skin gloss is assessed by Glossymeter, skin hydration is assessed by Corneometer, TEWL is assessed by Vapometer, and skin elasticity is assessed by Cutometer. VISIA-CR and VISIA-7 are used in skin radiation and wrinkle visualization.
Clinical assessment is performed by expert visual grading on
