To describe the progressing severity of facial signs and their links with perceived age, of Chinese men and women.
Full-face photographs of 438 Chinese subjects (220 men, 218 women) differently aged (18-80 years) were taken. These photographs afforded a zoom on 5 facial signs of aging: forehead and crow's feet wrinkles, nasolabial fold, marionette lines and ptosis of the lower face. A panel of 15 experts graded each sign, using the Asian skin aging atlas reference. A naïve panel of 80 Chinese women (20-60 years) was asked to attribute an apparent age.
Despite slight differences in severity between genders, men and women share in common a rather regular progression rate, correlated with perceived ages. 15% of men were judged older by more than 10 years, and all 5 signs were found more severe than the means of the other 85%. Forehead and Crow's feet wrinkles appear more pronounced in men. Ptosis is slightly more pronounced in women. Nasolabial fold does not differ. Marionette lines show distinct changes: those of men show a lessened severity and a slower rate of progression. In contrast with changes in facial signs with real ages, the upper face seems privileged in the perception of ages in women whereas the latter seems more focusing on its lower part in men.
The facial skin aging process in Chinese subjects presents an almost linear progression with perceived ages, common to both genders, at the exception of marionette lines that are more marked and more rapidly progressing in women.
描述中国男性和女性面部特征严重程度的进展及其与感知年龄的关系。
对 438 名不同年龄（18-80 岁）的中国受试者的全脸照片进行拍摄。这些照片提供了 5 种衰老迹象的特写镜头：额部和鱼尾纹、鼻唇沟、木偶纹和下面部下垂。一个由 15 名专家组成的小组使用亚洲皮肤衰老图谱参考标准对每个标志进行分级。一个由 80 名中国女性（20-60 岁）组成的天真小组被要求归因于一个明显的年龄。
尽管男女之间的严重程度略有差异，但男性和女性共同具有相当规律的进展速度，与感知年龄相关。15%的男性被认为比实际年龄大 10 岁以上，所有 5 个标志都比其他 85%的平均值更严重。额部和鱼尾纹在男性中更为明显。下面部下垂在女性中略为明显。鼻唇沟没有差异。木偶纹表现出明显的变化：男性的木偶纹严重程度降低，进展速度较慢。与面部特征随实际年龄的变化不同，女性的上半张脸在感知年龄时似乎更受优待，而男性则更关注其下半张脸。
中国受试者的面部皮肤衰老过程在两性中表现出与感知年龄几乎呈线性进展的趋势，但木偶纹除外，女性的木偶纹更为明显，进展速度也更快。
