Lycopene also has the function of reducing skin damage caused by radiation or ultraviolet (UV). When skin is irradiated by ultraviolet rays, lycopene in skin combines with free radicals generated by ultraviolet rays to protect skin tissue from damage. Compared with the skin without ultraviolet irradiation, lycopene decreased by 365,438+0% ~ 46%, and the content of other components remained almost unchanged. Studies have shown that by ingesting food rich in lycopene, you can resist ultraviolet rays and avoid erythema caused by ultraviolet radiation. Lycopene can also quench free radicals in epidermal cells, and has obvious desalination effect on senile plaques.

Extended data
Lycopene is widely found in tomatoes, tomato products, watermelons, grapefruit and other fruits. It is the main pigment in ripe tomatoes and one of the common carotenoids. From 65438 to 0989, MASCIO found that lycopene has the highest quenching activity for singlet oxygen among all carotenoids. Subsequently, the research on the function of lycopene has become a hot spot, involving the absorption and metabolism of lycopene, reducing the risk of prostate cancer and other tumors and cardiovascular diseases, and the extraction and determination methods of lycopene.
At present, lycopene is not only a natural pigment, but also widely used in functional foods, medicines and cosmetics.
