What it is used for
- Warts and verrucas
- Acne and blackheads
- Corns and calluses
- Dandruff and scaly scalp conditions
- Psoriasis scaling (when advised)
How it works
Salicylic acid softens and helps shed the outer layer of skin, which removes thickened skin, unblocks pores and gradually wears away warts and corns.
How it is taken
Available as gels, liquids, plasters, pads, shampoos and ointments at different strengths for different uses. Apply only to the target area exactly as the label or your clinician directs, protecting the surrounding healthy skin. Wart and corn treatments often need repeated application over several weeks.
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
- Mild burning, stinging or skin peeling
- Dryness or redness around the treated area
Serious effects — get help

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
