Can you look at a mole?
We can look, but we cannot clear it — and this is the firm limit of the service.
Assessing a pigmented lesion properly requires dermoscopy: a magnifying instrument with polarised light held against the skin, revealing structures no photograph captures. Nothing sent from a phone substitutes for it.
So anything new, changing, growing, itching, bleeding, or asymmetric in colour or border gets referred for in-person assessment rather than reassured from an image. We would far rather over-refer than miss a melanoma, and that is the correct way round.
Why do you need three photographs?
Because distribution is half the diagnosis. Where a rash is, and where it is not, distinguishes conditions that look identical close up. Eczema in the elbow creases, psoriasis on the extensor surfaces, scabies in the finger webs — a close-up of a single patch loses all of that.
My rash does not look red. Does that change things?
No — and this matters on brown and black skin. Inflammation frequently appears violet, grey, dark brown or simply darker than surrounding skin rather than red, and a great deal of teaching material does not show it that way.
Cellulitis, eczema and drug rashes are all missed for this reason. It is accounted for here — assessment goes on warmth, swelling, texture, distribution and change rather than on whether something looks red.
Can I just have a steroid cream?
Sometimes exactly right, sometimes the worst option available. Steroid on a fungal infection suppresses the redness while the fungus spreads, producing an altered, hard-to-recognise rash — and it is a common reason a straightforward problem becomes a difficult one.
If a rash improves on steroid and flares worse every time you stop, that pattern itself suggests fungus.
Am I using enough cream?
Almost certainly not. Under-application is the single commonest reason skin treatment appears to fail.
Use the fingertip unit: a line of cream from the fingertip to the first crease covers an area about the size of two flat adult palms. Measured that way, most people discover they have been using a small fraction of the intended amount.
Can you remove a mole, wart or skin tag?
No — anything requiring a procedure needs doing in person, and we will refer you. That covers excision, biopsy, cryotherapy and cautery.
Worth knowing that removal of a lesion purely for cosmetic reasons is not usually available on the NHS, and that a mole should never be removed cosmetically without it being examined and, where appropriate, sent for histology first.
How long until acne treatment works?
Six to eight weeks before you can fairly judge it, and it frequently gets worse in the first two. That initial flare is expected rather than a sign of failure, and it is the point at which most people give up.
Take a photograph in the same light every week. Acne improves too gradually to notice in a mirror.
When is a rash an emergency?
999 or A&E for: a rash that does not fade when pressed with a glass, particularly with fever or headache; blistering or peeling skin, or sores in the mouth, eyes or genitals; facial swelling with difficulty breathing; or an area of skin that is rapidly spreading and painful out of proportion to how it looks.
Everything else — which is the vast majority of skin problems — can be assessed calmly, and often very well, from good photographs.
