ACETYL CARNOSINE

Acetyl Carnosine is a synthetic version of carnosine, a naturally occurring dipeptide found in the body. It acts as a powerful antioxidant, protecting skin cells from damage caused by free radicals and environmental stressors. Additionally, it helps to prevent glycation, a process where sugar molecules bind to proteins like collagen and elastin, leading to skin aging. This ingredient can help maintain skin elasticity and reduce the appearance of fine lines and wrinkles.
