COMPOSITIONS CONTAINING KXK TYPE PEPTIDES

摘要

The invention proposes a cosmetic composition comprising: -a peptide of formula R1 -K-AA-K-R2, in which K represents a lysine and AA an amino acid incorporating a ring, at least two of the atoms of which belonging to the peptide skeleton, R1 being either H or a lipophilic chain and R2 being either OH, or a lipophilic chain; and -an acceptable physiological medium. In a preferred peptide the amino acid AA is either a proline P, a ß-proline or a proline derivative Results on the activity of the compounds are obtained and on the general state of the skin and its appendages, in particularvia the stimulation of extracellular matrix components.
