Fades Acne Scars & Dark Marks

With consistent use, skin appears clearer, smoother, and more even — the kind of change you can finally notice in the mirror.

Firms, Tightens & Improves Skin Texture
GHK-Cu peptides help support collagen for a smoother, more refined-looking surface. Over time, skin feels firmer, looks less puffy, and develops a more lifted, structured appearance.
Uneven texture softens, and your complexion takes on a healthier, renewed look that reflects real skin improvement.
