Glycerin contributes to forming and maintaining the skin hydrolipid film.
Chemical molecule produced in the plant kingdom, glycerin has been discovered in 1783 by Swedish chemist Carl Wilhem Scheele, then in 1823 by French chemist Eugène Cheveul.
Staple moisturizing active in cosmetics, glycerin is capable of retaining several times its weight in water. For this reason, it combines emollient, humecting and protecting properties and compensate the skin natural lipids when defective.
In living organisms, glycerin is a crucial component of glycerids (fat and oils) and phospholipids, essential constituents of cellular membranes in all cells. Glycerin thus plays an important role in maintaining the epidermis cells integrity.
It contributes to forming and maintaining the skin hydrolipid film which has a protecting barrier function on the epidermis, and retain its water levels.
