How to use them
Alternate nights, for example Benzoyl Peroxide on Monday, Wednesday and Friday and 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 Peptides.

Frequently asked questions
Can I use Benzoyl Peroxide and 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 Peptides?
Apply Benzoyl Peroxide first, then 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 Peptides in the morning or at night?
Peptides: works morning or night. Use morning and night after water-based serums. Low-pH acids applied at the same time can break some peptides down.
Is Benzoyl Peroxide with Peptides safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Benzoyl Peroxide. Check with your doctor.
