Practical use of superoxide dismutase in cosmetic products

Description

Due to the short half-life and poor stability of natural SOD, the application of superoxide dismutase is affected, so chemical modification is carried out to improve its stability. In cosmetic applications, modified SOD is used to replace natural SOD. Common modified SOD includes polyethylene glycol modified SOD, dextran modified SOD, etc.

The application of superoxide dismutase in cosmetics mainly includes 1) As a cosmetic additive, it can prevent skin aging and protect skin; 2) Prevent and treat skin diseases. At present, many advanced cosmetics are added with SOD, such as SK-II, which can be made into cosmetics in the form of facial mask, lotion and cream, etc. As a SOD cosmetic, the activity of SOD in each l g of substrates should not be less than 100 U. A large number of data show that SOD is non-toxic and has no side effects, so it is widely used in cosmetics.
