The Science: How Benzoyl Peroxide Kills Acne Bacteria
Benzoyl Peroxide (BPO) is a highly effective over-the-counter acne treatment. Unlike antibiotics which can lead to bacterial resistance, BPO works by introducing oxygen into the pores, which kills the anaerobic Propionibacterium acnes bacteria on contact.
It also acts as a keratolytic agent, softening and peeling the outer layer of the skin to clear blocked pores. It is particularly effective for red, painful inflammatory acne pustules.
How to Avoid BPO Irritation and Staining
Always start with a low concentration of 2.5%. High percentages like 5% or 10% cause significant irritation without offering much additional efficacy. Apply BPO only as a spot treatment at night, and be aware that it can bleach colored pillowcases and clothing.
Top Acne Defense Solutions
Galderma's Benzac AC 2.5% gel is the gold standard dermatologist pick for active spot treatments.

Follow up with a soothing, non-comedogenic gel like Neutrogena's Hydro Boost to repair the skin barrier.
