Can You Use Vitamin C and Benzoyl peroxide Together?

Yes, but use them at different times of day

Keep them apart. Benzoyl peroxide is an oxidizer, and vitamin C is easily oxidized, so layering them risks wasting your vitamin C. Use them at different times of day or on different days.

How to use vitamin c and benzoyl peroxide in one routine

Morning

Cleanser, vitamin C, moisturizer, sunscreen

Night

Benzoyl peroxide treatment or wash, moisturizer

If you need benzoyl peroxide in the morning, move vitamin C to alternate mornings.

Why

L-ascorbic acid is an antioxidant that breaks down when it meets oxidizers. Benzoyl peroxide is a strong one.

Even if your skin is fine, applying them together is likely to blunt an expensive serum.

What to watch for

A benzoyl peroxide wash you rinse off leaves less on the skin than a leave-on gel, but separating them is still the safer default.
