How to use
- What it is and how it works
Adapalene is a topical retinoid that helps prevent blocked pores; benzoyl peroxide reduces acne-associated bacteria. The fixed combination treats comedones, papules and pustules without a topical antibiotic.
- Apply it as prescribed
Once daily at bedtime, apply a thin, even layer to clean, fully dry skin over the affected area. Avoid the eyes, lips, mucosa, cuts, eczema and sunburn. Wash your hands afterwards.
- Skin care and interactions
Do not use another topical retinoid or benzoyl peroxide product. Keep cleansers and moisturisers gentle and non-comedogenic, avoid abrasive or drying products, and use SPF 30–50+ daily. Benzoyl peroxide can bleach hair and coloured fabrics.
First 4 weeks. Photograph your face in the same light at the start; lesion counts fall before the change is obvious. Dryness, peeling and redness are expected and peak around week 2. Moisturise after the gel and use SPF each morning. Use white towels and pillowcases; benzoyl peroxide bleaches fabric and hair.
Weeks 4-12 and beyond. Tell your doctor immediately if you become pregnant or plan a pregnancy; the gel must be stopped. Stop and ask for review for severe burning, swelling or blistering, or if acne is worsening or scarring. At 12 weeks, compare photos with your doctor; if it has worked, the gel continues as maintenance.

How it compares
| Acne treatments compared | How it works | Best suited for | How often | Judged at | In pregnancy |
|---|---|---|---|---|---|
| Azelaic acid 15% | Clears pores, reduces bacteria and inflammation; no antibiotic or retinoid | Mild to moderate papules and pustules; sensitive skin | Twice daily | 12 weeks | Individual decision with your doctor |
| Adapalene + benzoyl peroxide | Retinoid unblocks pores; benzoyl peroxide kills bacteria | Comedones with papules or pustules; any severity; maintenance | Once nightly | 12 weeks | Contraindicated |
| Clindamycin + benzoyl peroxide | Topical antibiotic plus benzoyl peroxide to prevent resistance | Mild to moderate acne where inflamed spots dominate | Once nightly | 12 weeks maximum | Only after individual risk-benefit review |
Based on NICE NG198 (2021) first-line 12-week options and the EU product information for each medicine.
Side effects
Local irritation
Mild redness, dryness, stinging or peeling can occur, especially at the start. Use a gentle moisturiser and follow the prescribed adjustment plan. Stop and seek advice if the reaction is marked or persistent.
Sun sensitivity and bleaching
Treated skin may be more sensitive to sunlight. Benzoyl peroxide can bleach hair, towels, bedding and clothing; let the gel dry before contact with fabric.
Do not use if
- You are allergic to adapalene, benzoyl peroxide or another ingredient
- You are pregnant or trying to conceive
- The treatment area has cuts, eczema, severe irritation or sunburn
When to contact your doctor
- Facial swelling, breathing difficulty, widespread blistering, eye pain, light sensitivity or altered vision: seek urgent medical care
- You become pregnant or think pregnancy is possible: stop the treatment and contact your clinician
- Irritation remains painful despite reducing frequency, or acne is worsening or scarring
Storage
Keep the tube tightly closed in its original package, out of children's reach. Follow the temperature and expiry instructions on the label and do not use the product after it expires.
What to expect
Acne treatment is gradual. Judge the response at the planned 8–12-week review rather than adding more gel or other active products. New nodules, cysts or scars need an earlier assessment.
