UTILIZATION OF A PEPTIDE HAVING A LYSIN GROUP AND AN ALANINE GROUP IN THE TERMINAL POSITION FOR THE PREPARATION OF A DEPIGMENTING COMPOSITION, AND DEPIGMENTING COMPOSITION THUS OBTAINED

摘要

The invention relates to the utilization of a peptide comprised of a peptide chain comprising at one of its extremities a lysin group (Lys) and at its other extremity an alanine group (Ala), for the preparation of a depigmenting composition. Preferably, the number of amino acids forming the peptide chain is comprised between 2 and 10 included. As an alternative, said peptide is a dipeptide Lys-Ala. According to another alternative, said peptide is an hexapeptide Lys-Cys-Thr-Cys-Cys-Ala. These peptides present a good dipigmenting activity (figure 1), particularly for the attenuation of senescent pigmentary spots, or for hair colour lightening.
