Abstract:Skin photoaging induced by ultraviolet ray which damages the dermis and epidermis is mainly reflected in three aspects：wrinkles，dryness，and spots.The increasing pressure and environmental pollution accelerate the aging of skin.Therefore，how to ameliorate skin aging has aroused growing concern.Collagen peptides and elastin peptides with low molecular weights are active peptides prepared from collagen and elastin，demonstrating excellent anti-photoaging activity from the above three aspects.The mechanism of skin photoaging and the preparation of the collagen peptide and elastin peptide were reviewed.Furthermore，the anti-photoaging effects and mechanisms of collagen peptide and elastin peptide were discussed in terms of reducing wrinkles，moisturizing，and inhibiting melanin production.The review aims to provide scientific reference for the daily consumption of collagen peptide and elastin peptide and the development of peptide products.
