How to use them
Alternate nights, for example Copper Peptides on Monday, Wednesday and Friday and Salicylic Acid on Tuesday and Thursday, with a plain moisturiser night in between if your skin feels sensitive. If your skin is resilient and already used to both, you can try layering them: apply Salicylic Acid first, wait a few minutes, then apply Copper Peptides.

Frequently asked questions
Can I use Copper Peptides and Salicylic Acid together?
Yes, but not at the same time. Low-pH acids can break down peptides, and with copper they can also irritate. Use the acid at one time of day and the peptide at the other, or on alternate nights.
Which goes first, Copper Peptides or Salicylic Acid?
Apply Salicylic Acid first, then Copper Peptides. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
Should I use Copper Peptides in the morning or at night?
Copper Peptides: best at night. Use at night on nights without acids or vitamin C. A thin layer is enough.
Should I use Salicylic Acid in the morning or at night?
Salicylic Acid: works morning or night. Use as a cleanser daily or a leave-on 2% serum 3–4 times a week. It can dry out skin, so moisturise well.
Is Copper Peptides with Salicylic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Copper Peptides and Salicylic Acid. Check with your doctor.
