2.5–5% benzoyl peroxide applied as a leave-on gel or spot treatment. Benzoyl peroxide kills C. acnes bacteria directly and oxygenates pores — and unlike antibiotics, bacteria cannot develop resistance to it. At 2.5%, it is as effective as higher concentrations with significantly less irritation. Pair with a non-stripping cleanser and moisturizer to maintain barrier integrity.

Cleared my cystic acne when prescription antibiotics hadn't. Wish I'd started years ago.

2.5% is the sweet spot — effective without nuking your skin barrier.
