GHK-Cu

Goodpeptide

Copper peptide known for its potential to promote collagen production and skin repair.

Can I mix GHK-Cu with other ingredients?

Caution

AHAs (Glycolic, Lactic, etc.)

AHAs can reduce peptide effectiveness. Best to use acids and peptides in separate routines for maximum benefit.

Caution

BHAs (Salicylic Acid)

BHA's acidic pH may reduce peptide effectiveness. Consider using in separate routines (acids AM, peptides PM).

Caution

Vitamin C

Vitamin C's low pH may reduce peptide effectiveness. Copper peptides in particular may bind with vitamin C and reduce its potency. Consider waiting a few minutes between them or using in separate routines.

Info

Ceramides

Peptides and ceramides are both gentle and reparative. A perfect combo for anti-aging without irritation.

Info

Hyaluronic Acid

Hyaluronic acid + peptides is a hydrating anti-aging duo. Apply HA first (thinner), then peptide serum.

Info

Niacinamide

Peptides and niacinamide both support the skin barrier and collagen. Safe and beneficial to combine.

Info

Retinoids

Retinoid + peptides is a powerful anti-aging duo. Peptides signal collagen production while retinoids boost cell turnover.

Info

Growth Factors

Growth factors and peptides work through complementary pathways. EGF/PDRN signals cell repair while peptides boost collagen synthesis.
