ACETYL CARNOSINE

Safety grade: A

Acetyl Carnosine is a modified form of carnosine, a naturally occurring compound found in muscles and the brain. It's used in skincare because it can penetrate the skin more effectively than regular carnosine to help protect cells from damage.

This ingredient works as an antioxidant to protect skin from environmental stressors and free radical damage, helping to maintain skin health and support a more youthful appearance.
