The present invention relates to anti-photoaging carrageenan derivative hydrogel and application. On the one hand, carrageenan derivative hydrogel has excellent hygroscopic and moisturizing properties, which can form an invisible film to prevent UV damage to the skin and maintain a moist environment for the skin; on the other hand, it has strong antioxidant capacity and inhibits tyrosinase and elastase. It can effectively inhibit the production of melanin and the decomposition of collagen, and reduce skin aging caused by light damage. The carrageenan derivative hydrogel has no immunogenicity, has good air permeability and can maintain the moist environment of the skin, is safe, non-toxic and easy to apply. The invention is particularly suitable for anti-photoaging drugs, medical devices and skin care products, and can effectively reduce skin damage caused by photoaging. |
