Zusammenfassung:A method for assessing the ability of a chemical substance or of a chemical composition to prevent or to slow the appearance of signs of aging of the human skin or of the lips or even to eliminate the signs; the method including: -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.
