A method for identifying skin care composition-resistant skin-binding peptides is described. The skin care composition-resistant skin-binding peptides bind strongly to skin from a skin care composition matrix and are stable therein. Peptide-based skin benefit agents, such as skin conditioners and skin colorants, based on the skin care composition-resistant skin binding peptides are described. The peptide-based skin conditioners and skin colorants consist of skin care composition-resistant skin-binding peptide coupled to a skin conditioning agent or a coloring agent, either directly or through an optional spacer. Skin care and skin coloring product compositions comprising these peptide-based skin conditioners and colorants are also described.
L'invention concerne un procédé visant à identifier des peptides se liant à la peau et qui résistent à une composition de soin de la peau. Lesdits peptides, stables dans une matrice de composition de soin de la peau, se lient fortement à la peau. L'invention concerne des agents à base de peptides bénéfiques pour la peau, tels que des crèmes revitalisantes et des colorants pour la peau, qui contiennent les peptides de l'invention. Ces crèmes revitalisantes et colorants pour la peau se composent du peptide de l'invention couplé à une crème revitalisante ou à un colorant pour la peau, soit directement, soit par l'intermédiaire d'un élément d'espacement facultatif. L'invention concerne aussi des compositions de produits de soin et de coloration de la peau qui comprennent les crèmes revitalisantes et les colorants contenant lesdits peptides.
