Benzoyl peroxide and hexapeptide-9: keep them apart

Keep them apart

Use them at different times of day, with benzoyl peroxide in the morning and hexapeptide-9 at night, because they cancel each other out. Benzoyl peroxide can break down and weaken the helpful anti-aging effects of the peptide. You can use them safely by applying them in separate routines.
