Abstract

Objective

This study aimed to develop and validate a novel, integrated dynamic wrinkle assessment system based on standardized, real-time and multi-angle facial images and video recordings, and to explore its potential application in evaluating the anti-wrinkle efficacy of skincare products.

Methods

A standardized protocol was developed for a novel system integrating a high-precision positioning apparatus with synchronized, multi-angle high-speed cameras to capture facial expressions from a neutral to a maximal state. To ensure longitudinal consistency, a novel algorithm was used to select analysis frames based on angular congruence. The system's reproducibility and accuracy were validated by expert dermatologists using the intraclass correlation coefficient (ICC). The system's feasibility and effectiveness were assessed in an 8-week anti-wrinkle cream efficacy trial.

Results

The integrated dynamic wrinkle evaluation system demonstrated high inter-rater reliability (ICC >0.70) across 35 Chinese women, with ICC values exceeding 0.900 for key facial areas. In an anti-aging efficacy trial (n = 42), the system successfully detected and quantified significant improvements (p < 0.05) in both static and dynamic wrinkles following product use.

Conclusion

This study successfully developed and validated an all-in-one dynamic wrinkle photo grading evaluation system for personalized assessment of treatment outcomes following topical application of cosmetic products. The high accuracy of the clinician evaluations offers a new approach for assessing the effects of anti-aging skincare and cosmetic products, surpassing traditional static assessment methods.

一种新型的一体化动态皱纹评价系统：开发、验证及在化妆品行业中的应用。

目的：本研究旨在开发并验证一种基于标准化、实时、多角度面部图像和视频记录的新型综合动态抗皱评估系统，并探讨其在护肤品抗皱效果评估中的应用潜力。方法：采用高精度定位装置与同步多角度高速摄像机相结合的新型系统，开发了一种标准化的协议，以捕获从中性到最大状态的面部表情。为了保证分析帧的纵向一致性，提出了一种基于角度同余的分析帧选择算法。皮肤科专家使用类内相关系数（ICC）验证了该系统的重现性和准确性。在为期8周的抗皱霜疗效试验中评估了该系统的可行性和有效性。结果：综合动态皱纹评估系统在35名中国女性中显示出较高的评分可信度（ICC >0.70），关键面部区域的ICC值超过0.900。在一项抗衰老功效试验（n = 42）中，该系统成功地检测并量化了显著的改善(p)。结论：本研究成功开发并验证了一种一体化的动态皱纹照片分级评估系统，用于局部使用化妆品后治疗结果的个性化评估。临床医师评价的高准确度，超越了传统的静态评价方法，为抗衰老护肤品和化妆品的效果评价提供了新的途径。

期刊介绍： The Journal publishes original refereed papers, review papers and correspondence in the fields of cosmetic research. It is read by practising cosmetic scientists and dermatologists, as well as specialists in more diverse disciplines that are developing new products which contact the skin, hair, nails or mucous membranes. The aim of the Journal is to present current scientific research, both pure and applied, in: cosmetics, toiletries, perfumery and allied fields. Areas that are of particular interest include: studies in skin physiology and interactions with cosmetic ingredients, innovation in claim substantiation methods (in silico, in vitro, ex vivo, in vivo), human and in vitro safety testing of cosmetic ingredients and products, physical chemistry and technology of emulsion and dispersed systems, theory and application of surfactants, new developments in olfactive research, aerosol technology and selected aspects of analytical chemistry.
