How to Choose a Dermatologist in London: What to Look For (and What to Avoid)

If you’re searching for a dermatologist in London, chances are you’re ready to take action – not spend weeks comparing clinics. But with so many options (from Harley Street to high-street), it’s hard to know who to trust with your skin.

Here’s how to cut through the noise and choose a dermatologist who’s worth your time, trust – and investment.

1. Look for GMC-Registered Doctors and Consultants

It sounds obvious, but it’s worth stating: your dermatologist should be a medically trained, GMC-registered consultant. That means they’ve completed extensive training in diagnosing and treating skin conditions, and have the credentials to prove it.

At No. 23 Skin, all our dermatologists are NHS-experienced consultants and community dermatologists handpicked for their expertise – and their humanity.

Avoid: Clinics that don’t have Consultant Dermatologists as part of their team as they may be more cosmetic than what you’re looking for.

2. Prioritise Joined-Up Care – Not Just One-Off Treatments

Your skin is one organ. So, treating a single concern (like acne, pigmentation or rashes) in isolation often leads to short-term results.

Choose a clinic that takes a whole-skin approach – where your dermatologist, nurses and wider team talk to each other regularly. This kind of joined-up care delivers better, longer-lasting outcomes.

Look for: Seamless access to both medical and health expertise under one roof – not a pick-and-mix of treatments with no plan.

3. Ask About Diagnostics, Not Just Treatments

Great skin starts with great diagnoses. Whether it’s mole checks, hormonal acne, or chronic inflammation, your dermatologist should begin with listening – and leave you with a plan that makes sense.

At No. 23 Skin, we start every journey with a consultation and diagnosis phase. It’s the difference between quick fixes and real results. Any good clinic should follow this pattern.

Avoid: Clinics that jump to treatments without a proper consultation or try to sell packages before assessing your skin. If they try and sell you the earth, it is likely that they are not looking at your skin properly and specifically for your needs.

4. Consider Availability and Access

Let’s be honest – you’re busy. So whether you need a lunchtime consultation or after-work laser session, convenience matters.

Private dermatology should offer speed, flexibility, and discretion. If you’re waiting weeks for an appointment or dealing with clunky booking systems, it’s not a good sign.

Look for: Same-week consultations, accessible locations, and support that’s easy to reach when you need it. It is worth noting that often Consultant Dermatologists work part time in the private sector – you may not need to see them frequently, but it is worth finiding out how often they are in clinic for a steer on availabilty.

5. Trust Your Instinct (and Their Track Record)

Choosing a dermatologist is personal. You should feel heard, never rushed – and confident you’re in expert hands. Look at clinic reviews, but also at the type of language they use. Does it feel reassuring? Professional? Straightforward? Your kind of people?

We believe skincare should be clear, empowering, and free from fluff. That’s why we created No. 23 Skin.
