背景:皮肤“黄度”是一个抽象和主观的术语,没有明确的测量协议。目的是分析中国女性对皮肤黄度的自我感知和相关参数,并确定与这些感知相关的客观临床测量。
方法:在焦点小组讨论之后,定义了皮肤泛黄的标准,并通过志愿者的面部图像排名进行验证。对185名妇女进行了类型学研究。参与者被分组为黄色(颜色均匀性,亮度和透明度(CUBT)黄色刻度等级>3,色度b*值>16)和非黄色(CUBT黄色刻度等级<2,b*值<14)组。参与者自我评估他们的皮肤泛黄,透明度,皮肤均匀性,迟钝,辐射,油性,和纹理。对皮脂腺毛孔进行了专家评估,眼区色素沉着,色素性斑点和CUBT评分。使用角膜测量仪对皮肤进行仪器分析,粘度计,mexameter色度仪,年龄的读者。
结果:黄色组的女性自我评价她们的皮肤明显暗淡,不那么均匀,且辐射小于非黄色组女性(P≤0.05)。在黄色皮肤的女性中观察到较高水平的眼部区域色素沉着和较低的面部皮肤均匀性和亮度(P<0.001)。CUBT专家分级显示较低的粉红色肤色,但是米色明显更高,黄色,黄皮肤组女性的橄榄色色素沉着(P≤0.05)。黑色素和b*值在皮肤发黄的女性中显著较高,而L值显著较低。
结论:中国女性自我感知的皮肤发黄与色度测量值相关,以及眼部色素沉着和CUBT参数的专家评估。
BACKGROUND: Skin \"yellowness\" is an abstract and subjective term, without a definitive measurement protocol. Objectives were to analyze Chinese women\'s self-perception of skin yellowness and associated parameters and identify objective clinical measurements that correlate with these perceptions.
METHODS: Following focus group discussions, criteria for skin yellowness were defined, and validated by volunteer rankings of facial images. A typology study of 185 women was performed. Participants were grouped into yellow (Color
Uniformity, Brightness and Transparency (CUBT) yellow scale grade > 3, chromameter b* value > 16) and non-yellow (CUBT yellow scale grade < 2, b* value < 14) groups. Participants self-evaluated their skin on yellowness, transparency, skin
uniformity, dullness, radiance, oiliness, and texture. Expert assessments were performed to grade sebaceous pores, ocular area pigmentation, pigmentary spots and CUBT scores. Instrumental analysis of the skin was employed using corneometer, sebumeter, mexameter chromameter, and AGE reader.
RESULTS: Women in the yellow group self-evaluated their skin as significantly duller, less uniform, and less radiant than women in the non-yellow group (P ≤ 0.05). Higher levels of ocular area pigmentation and lower facial skin
uniformity and brightness (P < 0.001) were observed in women with yellow skin. CUBT expert grading showed lower pink skin color, but significantly higher beige, yellow, and olive pigmentation (P ≤ 0.05) in women in the yellow skin group. Melanin and b* values were significantly higher in women with yellow skin while L value was significantly lower.
CONCLUSIONS: Self-perceived skin yellowness in Chinese women correlates to chromameter and mexameter measurements, as well as expert evaluation of ocular pigmentation and CUBT parameters.
