How to use them
Alternate nights, for example Copper Peptides on Monday, Wednesday and Friday and PHA 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 PHA first, wait a few minutes, then apply Copper Peptides.

Frequently asked questions
Can I use Copper Peptides and PHA 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 PHA?
Apply PHA 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 PHA in the morning or at night?
PHA: works morning or night. You can use it daily. It is a good first acid, or a way to keep exfoliating on retinoid "rest" nights if your skin tolerates it.
Is Copper Peptides with PHA safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Copper Peptides. Check with your doctor.
