The impacts of physical fatigue upon some facial signs, induced by a whole day work, have been previously described on Caucasian women. This study aimed at assessing those possibly experienced by Chinese working women under comparable conditions.
Standard photographs of 60 Chinese women working in the same company (aged 20-40 years) were taken at three occasions during their working day (just before, at 4 and 8 h). Focusing on facial signs allowed a panel of experts to grade their respective severities, helped by a referential atlas dedicated to Asian skin. A naïve panel, comprising 64 Chinese women (aged 20-60 years) graded, through an analogic 0-10 scale, the global facial aspect of each subject, particularly its tired-look and dullness and estimated the age of each subject (perceived age). Paired-comparisons in blind and random modes (T0/T4, T4/T8, T0/T8) allowed this naive panel to assess the subjects with a younger/older look, a dullest aspect.
A daily work induces, in Chinese women, changes in some facial signs (Nasolabial, Periorbital and Inter-ocular wrinkles, Cheek skin pores). The latter appear more marked between T0 and T4 than between T4 and T8. As compared to those observed among Caucasian women, these changes, although subtle, are of a higher amplitude and concern different facial signs. The naïve panel allowed to describe an increase in the tired look and dullness along the day, more so among the older group (31-40 years), together with an increased perceived age. Tired look, dullness and perceived age appear strongly linked.
Despite some possible differences in working conditions, some facial signs of Chinese women seem more affected by a fatigue induced by a working day in urban environment, than those of Caucasian women in similar conditions.
先前已有研究描述了整日工作引起的身体疲劳对白人女性某些面部特征的影响。本研究旨在评估中国职业女性在类似条件下可能出现的面部特征变化。
选取了60名在同一家公司工作的中国女性（年龄在20至40岁之间），在工作日的三个时间点（上班前、工作4小时后、工作8小时后）拍摄标准照片。由一组专家根据专门针对亚洲皮肤的参考图谱，对面部特征的严重程度进行分级。另一组由64名中国女性（年龄在20至60岁之间）组成的普通小组，通过0至10的模拟量表，对每个受试者的整体面部外观，特别是疲劳感和暗沉程度进行评分，并估计每个受试者的年龄（感知年龄）。通过盲法和随机模式进行配对比较（T0/T4、T4/T8、T0/T8），让这个普通小组评估面部看起来更年轻/更年长、更暗沉的受试者。
日常工作会使中国女性的一些面部特征（鼻唇沟、眶周和眼周皱纹、脸颊毛孔）发生变化。这些变化在T0和T4之间比在T4和T8之间更为明显。与白人女性相比，这些变化虽然细微，但幅度更大，且涉及不同的面部特征。普通小组发现，随着时间推移，疲劳感和暗沉程度会增加，在年龄较大的组（31至40岁）中更为明显，同时感知年龄也会增加。疲劳感、暗沉程度和感知年龄之间似乎存在密切联系。
尽管工作条件可能存在一些差异，但城市环境中工作日导致的疲劳对中国女性某些面部特征的影响，似乎比类似条件下的白人女性更大。
