The invention relates to a peptide of formula R -K-AA-KR, AA being an amino acid having a ring of which at least two atoms are part of the peptide backbone, R being either H or a lipophilic chain, and R being either OH or a lipophilic chain. AA can in particular represent proline, β-proline or a derivative of proline. The nitrogenous ring may be provided with at least one substituent chosen in particular from an NH group, an OH group or an imine. The invention also relates to a composition comprising this peptide in a dermatologically favorable environment, especially for the field of cosmetics or dermo-pharmacy. An improvement in the general condition of the skin can be seen, especially in terms of hydration, suppleness and elasticity, texture, appearance, thinning and hair loss. |
