Moisturizing and antisebum effect of cosmetic application on facial skin

Background Water content of the stratum corneum and skin surface lipids are important factors in the appearance and function of skin. High water content and low sebum secretion are considered main features of fair skin. Aim This paper aims to study the change of skin physiological parameters after cosmetic application. Methods The skin water content, transepidermal water loss, and skin sebum secretion on different regions of the facial skin before and after the cosmetic application were measured using Corneometer, Tewameter, and Sebumeter, respectively. Results The cosmetics kept higher water content and lower transepidermal water loss, at the same time lower sebum secretion 4  and 8 h after the cosmetic application, compared with those before it. The situation was maintained in the following 3‐week continuous use of the cosmetics. Conclusion The cosmetic application on human facial skin could provide some moisturizing effect and at the same time some antisebum effect according to different regions on facial skin, which favored the maintenance of good skin physiological function after applying skin care products.
