Can you use benzoyl peroxide every day?

Should you use benzoyl peroxide every day?

Daily use is reasonable if your skin tolerates it and your product directions allow it. Benzoyl peroxide treats mild to moderate acne by reducing acne causing bacteria. NHS Highland lists its 5% aqueous gel as a first treatment for mild acne, with once or twice daily application. Sensitive or irritated skin needs a slower schedule, not an automatic move to twice daily.1234

Start with the lowest available strength. Read the packet for your exact product, even if the front of the box has given most of its space to looking decisive. A wash is rinsed off; a leave on gel stays on the skin. The word "gel" appears on both, which is an ambitious amount of ambiguity for one syllable.5

How to start using benzoyl peroxide

1. 1Test a small amount on one or two small affected areas for three days before using a new product more widely. If there is no reaction or discomfort, follow its directions.
2. 2Wash your hands. For a leave on gel, gently clean and dry the affected skin, then apply a thin layer. For a gel wash, wet the area, wash with a small amount for one to two minutes, then rinse and pat dry.
3. 3Wash your hands afterwards. Keep benzoyl peroxide away from your eyes, mouth and nose, and do not apply it to infected or broken skin.
4. 4Begin once daily rather than jumping straight to twice daily. Follow the package or prescription schedule; do not apply a double dose after missing one.

What belongs in the rest of your routine?

Use a mild cleanser without scrubbing. For dryness, choose a fragrance free, water based moisturizer. Use sunscreen and avoid sunbeds because benzoyl peroxide increases sensitivity to sunlight. Keep the product away from hair and colored fabrics because it can bleach them.1256

Avoid abrasive cleansers and drying alcohol products. Only combine benzoyl peroxide with other acne treatments when your pharmacist or doctor approves the combination. Retinoids and antibiotics can be part of an effective treatment plan, and benzoyl peroxide is used alongside acne antibiotics to help prevent antibiotic resistance.135

What if daily use irritates your skin?

Dryness, peeling and slight stinging can occur. Use smaller amounts and reduce application to every other or third day until your skin gets used to the treatment. Waiting 10 to 15 minutes after washing before applying an acne medicine can also help. Speak to a pharmacist or doctor if symptoms persist or bother you.125

Get prompt medical help for burning, blistering, swelling or a rash. Stop using benzoyl peroxide and seek immediate medical help for hives, throat tightness, trouble breathing, faintness or swelling of the face, lips or tongue.1

How long should you give it?

Expect initial improvement in about four to six weeks; acne treatments can take up to three months to work. Arrange a review if there is no improvement after four to six weeks, and do not keep treating without advice beyond 12 weeks if nothing has improved. Seek help sooner for worsening acne, painful nodules or cysts, scarring or emotional distress.1256

Who should check before starting?

For children under 12, speak to a doctor first. Do not use benzoyl peroxide if you have had an allergic reaction to it. It can usually be used during pregnancy, but check with your doctor. During breastfeeding, get approval from a pharmacist or doctor and avoid applying it to the breasts.15

For regular use, storage matters too: benzoyl peroxide can break down into benzene, especially with heat or prolonged storage. Follow the package storage instructions. If concerned about benzene, replace products every 10 to 12 weeks and discard products exposed to temperatures above 78°F. Research remains limited and ongoing; current findings have not linked regular use to increased cancer risk.7
