METHOD FOR ASSESSING THE ABILITY OF A SUBSTANCE OR OF A COMPOSITION TO PREVENT, SLOW OR ELIMINATE THE SIGNS OF AGEING OF THE SKIN OR OF THE LIPS

摘要

A method for assessing the ability of a chemical substance (S) or of a chemical composition (C) to prevent or to slow the appearance of signs of ageing of the human skin or of the lips or even to eliminate said signs; said method comprising: - a step a) of bringing the chemical substance or the chemical composition into contact with fibroblast cells of the "young" human dermis taken from a culture medium at the passage R6; - a step b) of bringing senescent cells of fibroblasts of the human dermis into contact with the cells of "young" fibroblasts from step a); and - a step c) of measuring the senescence input of the cells of "young" fibroblasts and of comparing it with a reference value.
