  • the skin elasticity is decisively shaped by the collagen fibrils in the dermis, the specific conformation of the collagen being achieved by the incorporation of water molecules.
  • SC stratum corneum
  • Ceramides are lipophilic amides of long-chain fatty acids, which are generally derived from sphingosine or phytosphingosine. This class of endogenous fatty substances has gained considerable importance since they have been recognized in the intercellular space between the corneocytes as key components for the structure of the lipid bilayer, ie the permeability barrier, in the stratum corneum of human skin. Ceramides have molecular weights of significantly less than 1000, so that the external site of a cosmetic formulation makes it possible to reach the site of action. The external application of ceramides leads to the restoration of the lipid barrier, which can cause the described disorders of the skin function to be counteracted [cf. R.D. Petersen, Cosm. oil. 107, 45 (1992)].
