Evaluation of the antiwear‐ability/scratch‐resistance efficacy of makeup products by in vitro test method application

Abstract Objective The objective of this study is to propose a method for assessing the antiwear‐ability (AW) or surface scratch‐resistance (SR) efficacy of makeup products through in vitro experiments. Materials and method The method primarily involves measuring the change in weight as a means of evaluating the overall effectiveness. AW/SR effects are evaluated by applying a fixed amount of makeup product on artificial fake skin and comparing the weight difference after simulated friction/scratch. Results The in vitro results indicate that this method is easy to operate and yields repeatable data. It consistently reflects differences between samples when compared to clinical studies. Conclusions This method effectively compares the AW/SR effects of makeup products and demonstrates utility in evaluating product efficacy and difference. It holds great scientific and practical value.
