Many common skin problems are managed well by GPs and pharmacists. A dermatologist (a doctor specialising in skin, hair and nails) is most helpful when a problem is uncertain, severe, persistent, or not responding to standard treatment.

## Consider seeing a dermatologist if

- A rash or skin condition has not improved after several weeks of the treatment you have been given.
- Eczema, psoriasis or acne is affecting your sleep, work, school or confidence.
- You have a mole or skin lesion that is new, changing or looks different from your others.
- You need treatment that GPs cannot usually start, such as isotretinoin for severe acne or systemic treatment for eczema or psoriasis.
- You would like a clear diagnosis and a long-term plan for a recurring problem.
- Your child has a birthmark, haemangioma or skin condition that worries you.

## Get urgent help instead if

- You have swelling of the lips, tongue or throat, or difficulty breathing: call 999.
- You have widespread blistering or peeling skin, or a rash with fever and feeling very unwell: seek same-day medical care.
- A mole is changing quickly, bleeding or you are worried about melanoma: contact your GP promptly, as an urgent NHS referral may be needed.

## NHS and private routes

On the NHS, you see your GP first, who can refer you to a hospital dermatology service. Urgent suspected skin cancer referrals are prioritised; routine referrals can involve a wait.

Privately, you can book directly with a consultant dermatologist without a referral if you are paying for yourself. If you are using health insurance, most insurers ask for a GP referral and a pre-authorisation number first. After a private consultation, your GP can be kept informed with your consent.
