Description

technical field [0001] The invention relates to the fields of natural medicinal chemistry and cosmetics, in particular to a Chinese herbal medicine Snow Lotus for anti-aging in cosmetics or medicines, preferably anti-photoaging. Background technique [0002] Studies have shown that both free radicals and ultraviolet rays are one of the factors of skin aging, and photoaging is mainly caused by medium-wave ultraviolet (UVB, 290-320nm) and long-wave ultraviolet (UVA, 320-400nm) in sunlight. Ultraviolet rays can significantly promote the aging of human skin. The risk of skin aging in high-exposure groups is twice that of low-exposure groups, and the aging occurs 10 years earlier. Long-term exposure to sunlight and ultraviolet rays can cause skin photoaging and cause serious cosmetic problems. Therefore, in recent years, it has attracted much attention from the industry. Anti-aging and anti-photoaging products have come out one after another. Related research is in full swing, bu...
