[PROBLEMS] By applying an ultraviolet scattering agent or an ultraviolet absorber to scatter or absorb ultraviolet rays directly from the surface of the skin, the protective function of the skin cells inside the skin is functioning normally. It provides a photo-aging agent for preventing skin aging. [Measures] The photoaging inhibitor contains α-linolenic acid derivatives contained in perilla oil, flaxseed oil, perilla fruit oil, chia seed oil, saca ink, or green nut oil as active ingredients. This anti-aging agent can suppress the fall of the collagen production amount of human dermal fibroblasts, and can use it as a functional cosmetic. |
