With the deterioration of the environment and the increase of the ozone hole, the damage of ultraviolet rays to the skin has always been concerned by people. Although ultraviolet rays can not only combine with subcutaneous cholesterol to form vitamin D, promote calcium metabolism, help bone aging, but also have antibacterial and bactericidal effects, which are helpful for the treatment of skin diseases. But too strong ultraviolet rays can make the skin dry; accelerate skin aging; produce or deepen dark spots and freckles; excessive exposure to the sun may cause skin cancer; people with photosensitivity, exposure to ultraviolet rays can cause dermatitis.

According to the mechanism of sun protection, traditional sunscreen cosmetics are divided into physical and organic sunscreen cosmetics. Among them, the commonly used physical sunscreens such as nano-titanium dioxide and zinc oxide have the function of absorbing ultraviolet rays, but many consumers ignore their side effects. After being irradiated by ultraviolet rays, their photocatalytic activity is greatly enhanced, resulting in a large number of free radicals, which are the culprit of skin aging; and organic sunscreens are recognized as prone to increase the occurrence of skin cancer and Produce chemical allergy; There are some bigger problems respectively in the above-mentioned traditional sunscreen agent in general, so demand a kind of novel sunscreen cosmetics urgently.
