Make this make sense for you
What it is
Benzoyl peroxide is an over-the-counter topical widely used for inflammatory acne — the red, tender bumps rather than plain blackheads.
BPO
What it may help with
- • Papules and pustules
- • Inflamed breakouts
- • Reducing acne-associated bacteria on skin
How it works
It releases oxygen into the pore, an environment where the bacteria commonly associated with acne do not thrive well. It also has a mild peeling effect.
Common strengths
- • 2.5%, 4%, 5% and 10%
- • Lower strengths are often similarly effective and less drying
How often
Often once daily; some people start every other day, or as a short-contact wash.
Who commonly uses it
People with red, inflamed breakouts rather than purely comedonal acne.
Irritation risk
moderate
Possible side effects
- • Dryness and peeling
- • Redness
- • Bleaching of towels, pillowcases and clothing
Commonly works well with
- • Ceramides
- • Niacinamide
- • Non-comedogenic moisturizers
Use caution with
- Tretinoin — Some formulations are less stable together; many people use them at different times of day.
- Vitamin C — Often separated to different times of day for stability and comfort.
Beginner tips
- • 2.5% is a reasonable starting point — stronger is not automatically better.
- • Use white pillowcases and towels.
- • Moisturize consistently while your skin adjusts.
