Copper Peptide

Copper peptide, also known as Copper Tripeptide-1 (GHK-Cu), is a tripeptide naturally present in the body. It is one of the most studied and scientifically documented cosmetic peptides. Its concentration in the body is documented as decreasing with age, which is associated with visible signs of aging.
In scientific literature, Copper Tripeptide-1 is linked to supporting mechanisms involved in maintaining skin structure, notably type I and III collagen, elastin, and glycosaminoglycans, themselves related to firmness, suppleness, and visible skin density.
It is also associated, according to available data, with documented antioxidant properties and soothing properties linked to neutralizing free radicals and visibly reducing redness.
Several clinical studies report visible improvement in firmness appearance, visible reduction of fine lines, and improved skin radiance after regular application. In an independent study comparing Cu-GHK action to vitamin C and retinoic acid, a documented visible improvement was reported in 70% of those treated with copper peptide, versus 50% with vitamin C and 40% with retinoic acid.

In summary, Copper Tripeptide-1 is a well-documented active ingredient associated with multiple effects on skin structure appearance, protection, and visible quality, a benchmark ingredient for treatments targeting visible signs of aging.
