Neodermyl (INCI: Copper Lysinate/Prolinate) is a powerful collagen and elastin-stimulating ingredient. It is often described as a “needle-free alternative to injectables” and stimulates the fibroblasts in the skin to produce new collagen (type I and III) and elastin. It is therefore not a direct source of collagen but activates the skin to produce more collagen on its own.
