Abstract
Purpose: To investigate the methods for evaluating whitening efficacy of four commercially available skin lightening cosmetics. Methods: The efficacy was taken on human. Select 28 female volunteers between 25 and 45 years old for each group, and use the cosmetics on the inner side of the crank arm for 8 weeks continuously. We evaluated whitening efficacy through measuring the MI, L*and ITA° value of skin before using the cosmetics and after using the cosmetics 1 week, 2 weeks, 4 weeks and 8 weeks later. Results: The MI, L*and ITA° of skin were significantly different (p<.05) before and after. Conclusion: Statistical analysis on the MI, L*and ITA° of skin can show the lightening effect of cosmetics directly, thus the method can be used to verify the lightening effect of cosmetics.
目的: 探讨美白功效评价方法,对市售四款美白化妆品进行人体功效实验。 方法: 美白化妆品的人体评价。选择28名25岁-45岁的女性,按要求在曲臂内侧使用化妆品8周,分别测定使用化妆品前、使用 化妆品1周、2周、4周以及8周后的曲臂内侧皮肤MI值、L*值和ITA°值来评价美白功效。 结果: 8周后,测定曲臂内侧皮肤MI值、L*值和ITA°值与起始值相比较有显著性差异(p <.05)。 结论: 通过测定皮肤颜色的MI值、L*值和ITA°值的参数进行量化统计分析,可直观反映化妆品的美白效果,说明此方法可作为 评价化妆品美白功效的手段。
