To assess the agreement, after 1-month application of a popular and efficient anti-aging product, between self-perceived facial signs of aging and those detected and graded by an automatic A.I-based system, using smartphones' selfie images.
Of 1065 Chinese women, aged 18-60 years, from eight different Chinese cities were recruited. They were asked to apply daily, for 1 month, a referential anti-aging product onto their whole face. Selfie images were taken by all subjects at D and D and sent to our facilities for being analyzed through 10 different facial signs. At D , all subjects were asked to fill a questionnaire on the status of their faces, through six general statements.
A global agreement between both approaches is reached, particularly among women older than 40 years where the severity of facial signs is already more pronounced or among younger women who present at least facial signs scored above one grading units. This limit becomes, therefore, a prerequisite in the recruitment of Chinese subjects in the case of anti-aging applied studies and possible automatically based on automatic grading system. When respecting such conditions, the positive effects of the product on most facial signs can be demonstrated after 28 days of successive applications.
Such methodological approach paves the road in fulfilling the need of consumers of a better transparency in the claims of an anti-aging product.
评估在使用一款广受欢迎且高效的抗老化产品 1 个月后，通过智能手机自拍图像，基于人工智能的自动系统检测和分级的面部老化迹象与自我感知的面部老化迹象之间的一致性。
共招募了来自中国八个不同城市的 1065 名 18-60 岁的中国女性。要求她们每天在整个面部涂抹参考抗老化产品，持续 1 个月。所有受试者均在 D 和 D 拍摄自拍照，并发送至我们的设施，通过 10 个不同的面部特征进行分析。在 D 时，所有受试者都通过六个一般陈述来填写关于他们面部状况的问卷。
两种方法之间达成了总体一致性，尤其是在年龄超过 40 岁的女性中，面部特征的严重程度已经更为明显，或者在年龄较小的女性中，她们至少有一个评分超过 1 级的面部特征。因此，在招募中国受试者进行应用研究和可能基于自动分级系统进行研究时，这一限制成为一个前提条件。当遵守这些条件时，在连续使用 28 天后，产品对面部大多数特征的积极效果可以得到证明。
这种方法为满足消费者对抗老化产品宣称的更高透明度的需求铺平了道路。
