Use of xikvav peptides in the preparation of cosmetic compositions to improve skin firmness through increased cell adhesion

摘要

The invention relates to cosmetic compositions which are intended to improve the firmness of the skin by increasing adhesion of cutaneous cells in relation to one another and the basal lamina. The aforementioned compositions comprise a cosmetically-effective quantity of peptides having general formula X-isoleucyl-lysyl-valyl-alanyl-valine-Y, known as XIKVAV (figure 1). The invention also relates to the use of XIKVAV peptides in the preparation of cosmetic compositions which are intended to improve the firmness of the skin.
