Functions
1 | Carnosine is a dipeptide molecule, made up of the amino acids beta-alanine and histidine |
2 | Potent antioxidant, effectively quench active oxygen free radical |
3 | Complex heavy metals, eliminate and expel the toxicity of heavy metals |
4 | Prevent saccharification reaction, effectively quench the carbonyl free radical, reduce glycosylated allergic reaction products (cytotoxin) |
5 | Prevent the cross-linking of collagen and other macromolecules, reduce the formation of wrinkles. |
6 | Carnosine is highly concentrated in muscle and brain tissues, safe for use. |
Application
Used in products for anti-wrinkle, anti-aging, moisturizing, sunscreen, detoxification and other products.
Use Level 0.01-0.2 %
