Acne treatment

Benzoyl Peroxide

Also known as BPO

One of the most effective over-the-counter acne ingredients. It targets the bacteria behind breakouts and helps active spots clear faster.

What is benzoyl peroxide?

Benzoyl peroxide is a well-studied acne treatment. When it touches the skin it releases oxygen, which the bacteria linked to acne can't tolerate. It also has a mild peeling effect that helps keep pores clear.

What it does for your skin

  • Reduces the bacteria that drive red, inflamed breakouts
  • Helps active spots shrink and heal faster
  • Helps prevent new blemishes with regular use

How to use it

Apply a thin layer to clean, dry skin, either on individual spots or across an area that breaks out often. Start once a day. If you see dryness or flaking, use it every other day and moisturize. Let it dry fully before it touches fabric, and use white pillowcases if you can.

Who it's for

Benzoyl peroxide is best for inflamed, red breakouts. For mostly blackheads and congestion, salicylic acid is often the better fit. Many routines use both.

Common questions

Is benzoyl peroxide safe?
Yes, when used as directed. We cover recent questions about benzene in a separate article linked on this page.
Can I use benzoyl peroxide with retinol?
Yes, but not at the same time. Use benzoyl peroxide in the morning or on alternate nights from retinol.
Why is my skin peeling?
Mild dryness is common in the first few weeks. Use it less often and add a gentle moisturizer until your skin adjusts.
How strong should benzoyl peroxide be?
A 2.5% to 5% strength works well for most people with less irritation than higher strengths.
