Carnosine (β-alanyl-L-histidine)

Carnosine (β-alanyl-L-histidine) is a naturally occurring dipeptide with potent antioxidant and anti-glycation properties, making it a valuable ingredient in anti-aging skincare products. Mechanism of Action Carnosine’s benefits stem from its ability to: Scavenge ROS and RCS: It neutralizes reactive oxygen and carbonyl species, protecting skin cells from oxidative stress. Prevent Protein Glycation: It inhibits the damaging process of glycation in the extracellular matrix (ECM), preserving the skin’s structure and function. React with Aldehydes: It binds to low-molecular-weight aldehydes, preventing their harmful effects on skin proteins. Prevent Cross-linking: It inhibits the cross-linking of macromolecules like collagen and DNA, maintaining skin firmness and elasticity. Chelate Heavy Metals: It acts as a chelating agent, removing harmful heavy metal ions from the skin. Boost Regeneration: It supports the skin’s natural regenerative processes, contributing to wound healing.
