GHK-Cu/Niacinamide (2%/2%) is a topical skincare treatment that combines two powerful ingredients: GHK-Cu (a copper peptide) helps repair skin, boost collagen, and reduce fine lines. Niacinamide (Vitamin B3) calms redness, evens skin tone, and strengthens the skin barrier. Together, they support smoother, firmer, and healthier-looking skin with regular use.
