Abstract
The invention relates to products which are to be bound specifically to the membrane of a keratinocyte by means of a ligand-receptor bond. These products carry at least one ligand consisting of an oside residue selected from .alpha.-L-rhamnose, .alpha.-D-galactose and .alpha.-D-galactose-6-phosphate. By virtue of this specificity, it is possible to prepare cosmetic or pharmaceutical compositions having an improved efficacy in particular, for example for regeneration of the epidermis, for the treatment of psoriasis or for renewed hair growth.
