Gender‐related differences in the facial aging of Chinese subjects and their relations with perceived ages

Abstract

Facial aging is an ineluctable progressive process along decades. It comprises variable changes on the skin macro relief, that is, folds or wrinkles at different and specific facial sites (forehead, temples, upper lips…), ptosis, pigmentary spots etc the severity of which presents different onsets and that differently aggravates with time. Facial aging not only results from chronological aging, but also integrates the impacts of many other additional factors such as sun exposure (photoaging), lifestyles or aerial pollution. 1-5 As such, facial aging is an individual signature of a highly variable pattern between subjects, making some to be perceived older or younger that their real

Gender‐related differences in the facial aging of Caucasian French subjects and their relations with perceived ages and tiredness

“…sake of clarity, the average graded severities of the five facial signs with real age (assessed by experts) are shown in Figures 2-6. With regard to the slightly different scale ranges between genders, established in the Caucasian Skin Aging Atlas, Figures 2-6 were built, as ordinates, according to Caucasian women range, as uniform scale, that is, of comparable amplitudes in gradings.In common to results found on Chinese subjects,17 these changes with time present an almost linear pattern, albeit at different rates.Marionette lines excepted, that reach higher grading scores in women than those of men, only slight changes could be observed amongF I G U R E 5 Global changes in the severities of Marionette lines (average grades from experts) with the real ages of subjects (Mean ± Standard Error to Mean).

“…Wrinkles or skin folds at all facial locations, ptosis, color heterogeneity, dark spots, dark circles, etc are thereby key elements in the assessment of perceived age or even fatigue. 15,16 In a previous paper, 17 the differences in the severity of 5 facial signs of differently aged Chinese subjects of both genders were studied. Results showed that these facial signs show a rather regular rate of progression with real age, highly correlated with perceived ages, assessed by a naïve panel of 80 Chinese women.…”

Changes in facial signs due to age and their respective weights on the perception of age, on a tired‐look or a healthy glow among differently aged Chinese men

“…Unsurprisingly, the severities of most facial signs increased with time, at various rates, that is some almost regular, with others being erratic (vascular disorders). A previous study [21] has shown some gender differences in such changes between Chinese women and men, where, for example, the marionette line is more accentuated among Chinese women than men, at comparable ages. We acknowledge however that this study presents certain limitations since it was carried out on a relatively small cohort of differently aged Chinese men from the very same city.…”

“…These atlases, through high-quality standardized photographs of the faces of women and men of different ethnicities, allow standardized grading of the severities of some facial signs using specific scales (0-4 to 0- . Previous studies on women and men of different ethnicities [21,22] pinpointed how some facial signs at the upper or lower parts of the face (forehead wrinkles, nasolabial fold) played a more important role in attributing a perceived age, albeit for different reasons according to gender and ethnicity. In some studies [10,12,23,24], the perceived ages of hundreds of subjects were assessed by na€ ıve panels.…”
