To assess the alterations of some facial clinical signs after a working day in French Caucasian women.
Standardized photographs of full faces of 111 women of two different age classes were taken before and after a working day. Photos were submitted in blind (morning or evening) to a panel of 10 experts for scoring the severity of eight different facial signs using specific scales as established by previously published referential skin atlases. A panel of 60 naïve women gave their assessment of the overall look (more or less tired, aged, dull) from paired (morning/evening) photos given in blind. Subjects under study were asked to fill a questionnaire about their perceived state of tiredness before and after a normal working day.
All subjects felt a little more tired at evening although, surprisingly a little less in the older group (55-65 year) than their younger counterparts (25-35 year). Both groups were judged slightly less 'young' and 'more tired' at evening by the assessment panel, whereas the dull aspect remained unaltered. Four facial signs, among the 8 scored, showed subtle but significant changes, according to age class. Among older women, eye bags improved at evening as compared to morning, whereas glabellar wrinkles were found slightly accentuated. In younger subjects, nasolabial fold and crow's feet wrinkles were found of an aggravated severity score.
A normal working day induces, in the studied women, slight but detectable changes in some facial signs that vary (location, intensity) according to age.
评估法国白种女性在一个工作日后某些面部临床体征的变化。
对111名两个不同年龄组的女性在工作日前后拍摄全脸标准照片。照片以盲法（早晨或晚上）提交给由10名专家组成的小组，专家使用先前出版的参考皮肤图谱所确立的特定量表对八种不同面部体征的严重程度进行评分。60名普通女性组成的小组对盲法给出的配对（早晨/晚上）照片的整体外观（或多或少疲惫、显老、暗沉）进行评价。研究对象被要求填写一份关于正常工作日前后疲劳感的问卷。
所有受试者在晚上都感觉更疲惫一些，不过令人惊讶的是，年龄较大的组（55 - 65岁）比年轻组（25 - 35岁）疲惫感稍轻。评估小组判定两组在晚上看起来都稍显不那么“年轻”且“更疲惫”，而暗沉程度未变。在评分的8种面部体征中，有4种根据年龄组显示出细微但显著的变化。在年龄较大的女性中，与早晨相比，晚上眼袋有所改善，而眉间皱纹略有加深。在年轻受试者中，鼻唇沟和鱼尾纹的严重程度评分加重。
在被研究的女性中，一个正常工作日会导致某些面部体征出现轻微但可检测到的变化，这些变化根据年龄有所不同（位置、强度）。
