Copper Peptides + AHA
Copper Peptides + AHA — a note on combining copper peptides, which support repair and collagen signaling, with alpha hydroxy acids (AHAs) that exfoliate at a low pH, a pairing many suggest separating because the acidic environment can potentially destabilize the copper complex. Spacing them out helps each ingredient work effectively.
Key points
- AHAs such as glycolic and lactic acid exfoliate the skin surface and work best at a low, acidic pH.
- Copper peptides rely on a stable copper-peptide bond that an acidic environment may disrupt.
- Because of this potential interaction, many routines apply AHAs and copper peptides at different times, such as separate days or morning versus night.
- AHAs can increase sun sensitivity, so daily broad-spectrum SPF is important when exfoliating acids are part of a routine.
Frequently asked
Can I use copper peptides and AHAs at the same time?
It is generally suggested to separate them, since the low pH of AHAs may destabilize copper peptides and reduce their benefit. Using them on alternate days or at different times of day is a practical approach.
How long should I wait between applying an AHA and copper peptides?
Many people simply use them in separate routines, such as an AHA at night and copper peptides in the morning, to avoid direct interaction. If layering, allowing skin's pH to normalize first is the cautious choice.
