Microcapsules contain a peptide (I), and peptides (II) or (III) coupled to a PLGA-containing polymeric shell. The microcapsules can be used to enhance skin penetration of active ingredients encapsulated therein, particularly in the field of cosmetics. A process can be used for preparing the microcapsules, and compositions can contain said microcapsules. The microcapsules can be used as a transdermal delivery system for the active ingredients encapsulated therein.
