When to see a dermatologist
The signs that should not wait
Some skin problems settle on their own. Others do not. Here is when a consultation is worth booking.
Not every spot or patch needs an appointment. But some situations are worth booking for, and a few need prompt attention. The list below gathers the warning signs mentioned across the encyclopedia.
Book soon
- An over-the-counter treatment has not worked after 2 to 3 months
- A lesion changes shape, colour or size
- The condition is affecting your sleep or quality of life
- Flares are severe and not responding to your usual treatment
- Scarring is starting — the earlier this is addressed, the better
Go promptly
Signs of skin infection should not wait:
- Yellow crusts on the lesions
- Fever alongside a rash
- Redness visibly spreading from one day to the next
- Painful, widespread blisters (possible eczema herpeticum)
What to bring
A consultation is more useful if you arrive with a few things ready:
- How long it has been there and how it has changed
- What you have already tried, for how long, and with what result
- Any medicines you take, including over-the-counter ones
- Your skincare routine
- Photos of the lesions at their worst, if they come and go
Can I go straight to a dermatologist?
It depends on your health system. In many cases you need a referral from your family doctor.
What if a lesion is changing fast?
A lesion changing quickly in shape, colour or size should be assessed without delay.
