A new reference clinical atlas of facial signs dedicated to photoaging was applied to 301 Chinese women of various ages through standardized photographs. Such approach aimed at better describing the facial changes induced by both real/chronological age and sun exposure and their respective impact on two subcohorts of different behavior with regard to sun exposure. A total of 28 various facial signs were individually graded according to their severity by a panel of experts, and a perceived apparent age of each subject was assessed. Results showed that the severity of major signs significantly increased rather linearly with age, with a higher rate in sun-exposed subjects as compared with subjects who regularly avoid sun exposure. The severity of facial signs, all impacted by sun exposure, better correlated with perceived apparent age than real/chronological age. The protocol used in the present work, similar to that previously applied to two cohorts of French women, assigned a greater impact of sun exposure in the facial aging signs of Asian women - all clinical signs are influenced by extrinsic factors - as compared with Caucasian women of comparable ages, likely related to much more intense ultraviolet (UV) radiation.
一本专门针对光老化的面部体征参考临床图谱通过标准化照片应用于301名不同年龄段的中国女性。这种方法旨在更好地描述实际年龄/生理年龄和日晒所引起的面部变化，以及它们对两个在日晒方面行为不同的亚组人群的各自影响。由一组专家根据严重程度对总共28种不同的面部体征进行了单独分级，并评估了每个受试者的感知表观年龄。结果表明，主要体征的严重程度随年龄增长显著呈线性增加，与经常避免日晒的受试者相比，日晒受试者的增加速率更高。所有受日晒影响的面部体征的严重程度与感知表观年龄的相关性比与实际年龄/生理年龄的相关性更好。本研究中使用的方案与先前应用于两组法国女性的方案类似，表明与年龄相仿的白种女性相比，日晒对亚洲女性面部老化体征的影响更大——所有临床体征均受外在因素影响——这可能与更强的紫外线辐射有关。
