Abstract
|
|
|
|
Skin surface lipids are composed of sebaceous glands secreting lipids and epidermal disintegration lipids. The main components include triglycerides, free fatty acids, wax esters, squalene, cholesterol and so on. Skin surface lipids adhere to the surface of the skin and rely on their physical, chemical and biological properties to be important for skin health. This article reviews the relevant literatures at home and abroad, briefly describes the effects of skin surface lipids on skin moisturization, anti-oxidation and maintenance of micro-ecology, and mainly introduces the oxidation/metabolism of squalene/free fatty acids, which is more affected by external harmful factors than other skin surface lipids. As well as, the effects on skin health of squalene oxidation products and triglyceride metabolites are introduced. Above all, the oxidation/metabolism of skin surface lipids and the role of their products are illustrated in order to reveal the relationship between skin surface lipids and skin health and to provide a theoretical reference for the research and development of cosmetics by regulating skin surface lipids.
