Vitamin C and Benzoyl Peroxide

I want to start using a vitamin C serum.  I use a 2.5% benxoyl peroxide cream over breakout-prone areas (most of my face!) twice daily.  Using BP 2x daily is the only way I've found to keep my acne under control (and I have tried everything) so eliminating the BP or cutting back to once a day aren't options.  Can I use vitamin C serum before or after applying BP?


  • No, vitamin C and BP should not be on your skin at the same time because the BP is an oxidant and it will "use up" Vitamin C which is an anti-oxidant. Essentially they cancel each other out.
