Clinical evidence for wrinkle reduction, firmness, photoaging reversal, and comparison to retinol
The Science of Skin Renewal
The strongest clinical evidence for GHK-Cu comes from dermatology. A randomized, double-blind trial showed 55.8% wrinkle volume reduction. Head-to-head comparisons found it outperformed both vitamin C and retinoic acid for collagen production. This unit examines every major skin study and what the data actually shows.
