Abstract

The horny layer of the epidermis consists of keratinized flat cells surrounded and held together by lipid materials that are able from ordered structures were water molecules can be arranged with some type of regular spacing. When the amount or the composition of lipids around the skin cells is for any reason modified, the organization of water in water-oil compartments and the content itself of keratin structures can be dramatically affected. As a consequence, many mechanical and physiological properties of the skin are negatively influenced. Side effects of water depletion form the epidermis are the decreased resistance to environmental attacks and the reduction of the mechanical properties of the skin. The topical supplement of adequate lipid ingredients may reduce or resolve the cutaneous imbalances that lead to excessive superficial dryness. The so-called moisturizing effects and barrier repair properties are the key results of the topical application of lipids. For their complex compositions, vegetal lipids play a key role in the maintenance of water equilibrium in the skin. According to the acyl glycerides profile and the structure of the components of the unsaponifiable fraction, vegetal oils may exhibit lenitive, sebum equilibrating and emollient activity. Moreover, they may stimulate the skin repair processes, protect the body surface from the oxidative stress and from the sun irradiation, and in general slow down the skin aging process. Triglyceride composition and the ingredients of the unsaponifiable fraction are different in the different vegetal oil, so addressing specific application and industrial uses in cosmetics.
