Benzoyl Peroxide
A topical ingredient used in many products for breakout-prone skin to help keep the skin's surface clear; it can bleach fabric and cause dryness.
Benzoyl peroxide is a long-standing topical ingredient found in many products formulated for breakout-prone skin. It works at the skin's surface and inside the pore, and is commonly used in washes, gels, leave-on lotions, and spot treatments. In over-the-counter products it usually appears between about 2.5% and 10%.
One of the most practical things to know is that higher strengths are not necessarily better — lower concentrations can be just as useful and are far less likely to leave skin dry or irritated. A gentle way to start is a lower-strength product a few times a week, paired with a simple fragrance-free moisturiser to keep the skin barrier comfortable, and a broad-spectrum sunscreen during the day.
Benzoyl peroxide has a couple of quirks worth planning around. It can bleach fabric and hair, so it's wise to use white towels and pillowcases and let it absorb before it touches clothing. It can also be drying, especially early on, so introducing it slowly and moisturising well makes the adjustment easier.
Honest limits: benzoyl peroxide can genuinely help support clearer-looking, breakout-prone skin, but it isn't right for everyone. Persistent, painful, or widespread breakouts often involve deeper factors that surface products can't fully address. If your skin isn't responding after a consistent trial, or breakouts are severe, it's worth speaking to a skincare professional or GP about your options.
