化妆品人体功效评价的实验设计

Experimental design of efficacy evaluation of cosmetics

利用自变量、因变量和额外变量的有效控制方法,分析化妆品人体功效评价相关性与有效控制,利用实验设计常用的均衡、重复、随机、对照、盲法5种原则提出化妆品人体功效的设计原则,并阐述了化妆品人体功效评价研究的实验设计要点,为进一步完善化妆品人体功效评价实验设计提供更加科学的思路和方法,有助于研究者制定高质量的实验设计方案。

Using the effective control method of independent variables,dependent variables and additional variables,the correlation and effective control in efficacy evaluation of cosmetics were analyzed.The design principles of human body efficacy of cosmetics were proposed,including the five principles of equilibrium,repetition,randomization,control,and blinding that were commonly used in experimental design.The main points of experimental design for evaluating the efficacy of cosmetics were expounded.This paper might be helpful in providing more scientific ideas and methods for further improving the experimental design of cosmetic efficacy evaluation,and could help researchers to formulate high-quality experimental design schemes.
