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

Frequently asked questions
Can I use Benzoyl Peroxide and Copper Peptides together?
Yes, but not at the same time. Benzoyl peroxide is an oxidiser and may degrade delicate peptides. Keep them in different routines.
Which goes first, Benzoyl Peroxide or Copper Peptides?
Apply Benzoyl Peroxide 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 Benzoyl Peroxide in the morning or at night?
Benzoyl Peroxide: works morning or night. 2.5% works about as well as 10% and irritates less. Use as a short-contact wash or a spot treatment, and keep it away from fabrics.
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.
Is Benzoyl Peroxide with Copper Peptides safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Benzoyl Peroxide and Copper Peptides. Check with your doctor.
