ghk cu purple Copper Peptide (GHK-Cu) Powder Copper Peptides+ with GHK-CU Night

Clinical research has demonstrated that GHK-Cu is able to pass through the lipid barrier of the stratum corneum (the uppermost layer of skin) and to reach epidermal cells

And do you have to pin it or can you use it topically

The obtained results confirmed that the liposomes can be used as carriers for biomimetic peptides such as copper-binding peptide and that the GHK-Cu did not significantly affect the tyrosinase activity but led to 48.90 2.50% elastase inhibition, thus reducing the rate of elastin degeneration and supporting the structural integrity of the skin

Copper peptides vs retinoids Retinoids (retinol, tretinoin, adapalene) remain the "gold standard" for wrinkle treatment based on decades of research and FDA approval for wrinkle reduction
