If you are already using retinoids, AHAs, or other actives that increase cell turnover, adding GHK-Cu on top without adjusting your routine is asking for trouble

This layer acts like a protective sheath, so if you break it down with too many AHAs or retinoids, you can cause inflammation and irritation

For comprehensive anti-aging and skin repair, GHK-Cu offers broader benefits and is often used alongside other peptides for a multi-functional skincare approach

Using Niacinamide for acne reduction works even more effectively when paired with azelaic acid

Most copper peptide products are serums or creams and often have a faint blue tint, which comes from the copper itself
