Perceived age is important to women and is a primary driver for topical product use and facial cosmetic surgery. Changes in facial features and biophysical skin parameters with chronological age and their associations with perceived age have not been described in Asian populations.
To investigate the relationship between biophysical properties of the skin, visual features of skin ageing and perceived facial age in Chinese women.
Facial photographs were collected of 250 Chinese women, aged 25-70 years in Shanghai, China. The perceived facial age was determined and related to the chronological age for each participant and to a range of visual assessments of skin appearance and objective biophysical measurements of the skin. The profile of changes in these parameters with age was investigated together with the differences in those parameters for women judged to look younger than their chronological age and those judged to look older than their chronological age.
Large discrepancies in perceived age (up to 29 years) were found in women of the same chronological age. Each objective skin measure and visual assessment parameter had a stronger correlation with perceived age than with chronological age. The strongest relationships to perceived age were for wrinkles and hyperpigmentation. Skin colour, hydration and trans-epidermal water loss (TEWL) had weaker associations with perceived age. Women judged to look older than their chronological age had significantly higher scores than those judged to look younger for coarse wrinkles and hyperpigmentation across all age groups. The appearance differences between these groups were evident in composite facial images of the same average chronological age.
We have identified the skin attributes which differ with perceived age in Chinese women. Perceived age is a better measure of the biological age of facial skin than is chronological age in this population.
感知年龄对女性很重要,是她们使用局部产品和面部整容手术的主要驱动因素。然而,在亚洲人群中,尚未描述与年龄相关的面部特征和皮肤生物物理参数的变化及其与感知年龄的关系。
调查中国女性皮肤的生物物理特性、皮肤老化的视觉特征与感知面部年龄之间的关系。
在中国上海,共收集了 250 名年龄在 25-70 岁之间的中国女性的面部照片。确定了每位参与者的感知面部年龄,并将其与实际年龄相关联,同时还评估了一系列皮肤外观的视觉评估和皮肤的客观生物物理测量。研究了这些参数随年龄的变化特征,以及判断看起来比实际年龄年轻和看起来比实际年龄大的女性之间这些参数的差异。
在实际年龄相同的女性中,感知年龄(相差最大可达 29 岁)存在较大差异。每个客观皮肤测量值和视觉评估参数与感知年龄的相关性均强于与实际年龄的相关性。与感知年龄相关性最强的是皱纹和色素沉着。皮肤颜色、水分和经表皮水分流失(TEWL)与感知年龄的相关性较弱。与实际年龄相比,判断看起来年龄较大的女性在所有年龄组中,其粗糙皱纹和色素沉着的评分明显高于判断看起来年轻的女性。在相同平均实际年龄的复合面部图像中,这些组之间的外观差异明显。
我们已经确定了中国女性感知年龄差异的皮肤属性。在该人群中,感知年龄比实际年龄更能衡量面部皮肤的生物年龄。
