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 %
