Carnosine is a naturally occurring dipeptide composed of the amino acids beta-alanine and L-histidine. It is found naturally in human tissues such as muscles, brain, and skin. In cosmetic and pharmaceutical formulations, carnosine is valued for its powerful antioxidant and anti-glycation properties.
Carnosine helps protect the skin from oxidative stress, environmental damage, and glycation, a process where sugars bind to proteins like collagen and elastin, causing them to become stiff and less functional. By inhibiting glycation and neutralizing free radicals, carnosine helps maintain skin elasticity, reduce wrinkles, and slow visible signs of aging.
