When to see a dermatologist
Some skin problems belong with a specialist from the outset: changing moles, suspected skin cancer, severe or scarring inflammatory disease, and any rash that defies diagnosis or treatment.

Understanding it
About When to see a dermatologist, and what to do next.
GPs manage most skin disease well, but dermatology referral earns its place in specific situations: suspected skin cancer (fast-tracked on the NHS two-week-wait pathway), moderate-to-severe acne at risk of scarring, eczema or psoriasis failing standard treatment, unexplained rashes, blistering conditions, scarring hair loss, and lesions needing surgery or specialist diagnostics such as patch testing and biopsy. Delay costs most where scarring, of skin, follicles or confidence, is accumulating.
Referral routes matter in practice: NHS dermatology waits for routine problems are long in much of the country, while urgent cancer pathways remain fast. Knowing which category your problem belongs to, and pushing appropriately, is half the battle. Most people start with their GP, who can refer to a consultant dermatologist. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks depending on where you live, whereas an initial appointment with a private consultant is typically available within around two weeks.

Frequently asked
Common questions about When to see a dermatologist.
Quick, plain-English answers to what people ask us most.
-
When should I see a dermatologist rather than my GP?
Consider a dermatologist for persistent skin conditions that haven't improved with initial GP treatment, any changing mole or new skin lesion of concern, complex skin conditions like psoriasis or eczema needing specialist management, or cosmetic dermatology concerns.
-
What symptoms warrant urgent dermatology assessment?
A rapidly growing, bleeding, or changing mole, a non-healing sore, or a widespread severe skin reaction should prompt urgent assessment, as these can occasionally indicate skin cancer or a serious reaction needing prompt treatment.
-
Is delaying dermatology assessment dangerous?
For most chronic skin conditions, a short delay isn't dangerous, but for a suspicious changing mole or lesion, prompt assessment is important since some skin cancers are much more treatable when caught early.
-
Can a GP treat most skin conditions without a dermatologist?
Yes, many common skin conditions are effectively managed by GPs, with dermatologist referral reserved for cases that don't respond to initial treatment, are complex, or where there's diagnostic uncertainty or clinical concern.
-
How is a mole or skin lesion assessed by a dermatologist?
Assessment typically involves a detailed visual examination, often using a specialised magnifying tool (dermoscopy), and sometimes a biopsy if there's any concern about the nature of a lesion.
-
How quickly should a changing mole be assessed?
A mole that is changing in size, shape, colour, or is bleeding or itching should be assessed promptly, ideally within a couple of weeks, given that early assessment improves outcomes for skin cancer.
-
Dermatologist vs GP for skin concerns - what's the difference?
A GP can manage many common skin conditions and will refer on for anything needing more specialist input, while a dermatologist has specific additional training in diagnosing and treating a much broader and more complex range of skin, hair and nail conditions, including skin cancer.
-
When should I see a dermatologist, and how quickly can I be seen privately?
See a dermatologist for persistent, changing, or concerning skin issues. NHS dermatology waits can be 20-45+ weeks for non-urgent referrals; private dermatologists can often see you within about one to two weeks; suspicious lesions should be assessed via an urgent pathway.
