Dynamics of glycerin and water transport across human skin from binary mixtures

ConclusionThese studies confirm that glycerin enters HSC in substantial quantities and has a long residence time therein. The coupling between bulk water and glycerin transport projected from binary solution data suggests the net effect of glycerin is to slow water loss from the skin. The data support the concept of glycerin as a humectant with an excellent balance of skin penetration and retention characteristics; however, they do not rule out the possibility of an additional biological effect on skin barrier homeostasis.This article is protected by copyright.
