Carnosine is a natural dipeptide, which can scavenge free radicals, anti-oxidation, anti-glycosylation, promote cell metabolism and delay aging, especially for mature skin. 1. The water solubility is good, and the pH of 2% aqueous solution is about 8. 2.It is made of β-alanine and histidine linked by peptide bond, which is safe, non-toxic and has no side effects. 3. The small molecular structure can be absorbed directly through the pores and is easy to use.

*The histidine residues on the carnosine side chain can be used as hydrogen receptors to inhibit lipid oxidation including non-metallic ions. Carnosine can stably protect the cell membrane, especially as a water-soluble free radical scavenger, it can prevent the peroxidation of fine cells. Carnosine can also inhibit a series of other oxidation reactions, and carnosine can inhibit every step of the oxidation chain in the whole process in vivo. Carnosine can reverse this injury signal to fibroblasts and prevent premature aging of proteins and phospholipids.
