Lactic Acid (AHA) + Copper Peptides
Can you use Lactic Acid with Copper Peptides?
Yes, with timing. Use copper peptides and Lactic Acid at different times.
Why
Direct research is limited. Many experts suggest separating copper peptides from strong acids out of caution.
How to use them together
- Use the acid in the evening and copper peptides in the morning, or on alternate days.
Who should be careful
Stop if you notice irritation. People with very sensitive skin, rosacea or eczema should patch test new products first.

Lactic Acid (AHA): A gentler alpha hydroxy acid with a larger molecule than glycolic acid. Exfoliates and helps hydrate. Like all AHAs, it can increase sun sensitivity.
Copper Peptides: Mainly GHK-Cu, a copper-binding peptide studied for skin repair and remodeling.
