What it is used for
- Mild to moderate acne
- Blackheads and whiteheads
- Inflamed spots and pimples
How it works
Benzoyl peroxide reduces the acne-causing bacteria on the skin and helps clear blocked pores by removing excess dead skin and oil.
How it is taken
Comes as a gel, cream, lotion, face wash or bar. Apply to clean, dry skin over the affected area exactly as the label or your clinician directs, often starting at a lower strength to let the skin adjust. It can bleach hair, towels, bedding and clothing, so let it dry and take care with fabrics.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Dryness, peeling or flaking of the skin
- Mild burning, stinging or redness
- Skin feeling tight, especially when starting
Serious effects — get help
- Severe burning, blistering, swelling or crusting of the skin
- Signs of an allergic reaction such as facial swelling, hives or difficulty breathing
If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.
Interactions to watch
- Other drying or exfoliating skin products (such as strong scrubs or some acids) used at the same time may increase irritation
- Some topical acne medicines should be applied at separate times of day; check with your pharmacist
Who should take care
- Avoid contact with the eyes, mouth, nostrils and broken skin
- Use sun protection, as it can make skin more sensitive to sunlight
- Be aware it bleaches coloured fabrics and hair
- If irritation is severe, reduce frequency and ask your pharmacist or clinician
