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.

Disclosed is a callus lysate containing a callus metabolite without a loss of callus metabolite and its preparation method, a capsule containing a callus lysate prepared through encapsulation by coating the callus lysate with a natural polymer material and its preparation method, and composition for external skin application and a cosmetic composition that includes the callus lysate or the capsule containing the callus lysate as an active ingredient, wherein the callus lysate of the present invention contains a large amount of a callus metabolite without a loss of callus metabolite and thus allows penetration or absorption of callus metabolite directly into the skin, thereby providing effects of the callus metabolite to prevent and improve various skin diseases and symptoms.
