How a working day‐induced‐tiredness may alter some facial signs in differently‐aged Caucasian women

Abstract

A normal working day induces, in the studied women, slight but detectable changes in some facial signs that vary (location, intensity) according to age.

Assessing changes in some facial signs of fatigue in Chinese women, induced by a single working day

“…More importantly, these subtle changes (T8 vs. T0) in the same facial signs are of higher amplitudes (approx. 0.1-0.4 score units) than those previously observed in Caucasian women, that ranged 0.05-0.11 in comparable conditions (a one-day work) [12], although of a different age-distribution: Caucasian women comprised two groups of 25-35 years and 55-65 years. As example, the Periorbital wrinkles of the younger group of Caucasian women were not found statistically altered between T0 and T8, in contrast to what was observed here on the younger Chinese cohort.…”

“…As example, the fatigue induced by an 8-hours activity may well be differently felt from Monday to Friday. This latter day was chosen in the study on Caucasian women [12], as initially thought being the very day where fatigue was more impacting the facial traits.…”

“…a night or a day. Such are the cases of 'pillow or sleep lines' [11] or traces of fatigue induced by a working day [12], that were graded by a panel of experts, using a referential Atlas of Caucasian skin ageing [1]. The latter study, based on differently aged French Caucasian women, showed that some signs (Eye bags, Nasolabial fold or Glabellar wrinkles) were differently altered by a working day, at various extents according to age.…”

“…Similar to our protocol used in a previous work [12], a panel of 15 trained experts graded some facial signs, using the Referential Atlas of Asian skin ageing [2]. These scores aimed at detecting some facial signs that could possibly be subtly altered by an 8 hworking day.…”

Influences of age, ethnic group, and skin sites on a provisory skin marking, experimentally induced, in vivo

“…It has to be kept in mind that the global aging process of all physiologies may be summarized by the “less” common term. With age, humans memorize, see, hear, walk, sleep, breath, recover from efforts, with progressively lessened efficiencies. The human skin, although “fair enough to maintain most its properties up to the final act” (Pr A.M Kligman), illustrates such progressive declines, as less able to recover from a benign, provisory, and superficial deformation.…”
