The Most Common Skin Concerns in London – And How Our Dermatologists Treat Them

Wondering if your skin concern is worth seeing a dermatologist for? From moles to rosacea, here’s what brings patients through our London clinic doors – and how we help.

Living in a city like London has its perks. But when it comes to your skin? Pollution, stress, unpredictable weather and a packed schedule don’t always help. If you’re dealing with something that just won’t budge — or you’ve been putting off getting it checked — you’re not alone.

Here are some of the most common skin concerns we see at our London clinic, and how our dermatologists treat them with real results.

1. “Is This Mole Normal?”

Whether it’s new, changing, or just catching your attention for the first time, moles are one of the most common concerns we see — and rightly so. While most are harmless, some changes can be early signs of skin cancer.

What we offer:
At No. 23 Skin, we provide fast, consultant-led mole checks in London with dermoscopy and digital imaging when needed. If removal is required, we can do that too — right here, with histology included.

When to act: If a mole changes in size, shape, or colour, or starts to itch or bleed — get it checked.

Patient journey: Mole checks are one of the most common appointments we see, and helping our patients get quick reassurance is vital. Read about real patients here.

2. Adult Acne That’s More Than Just Hormonal

Cystic spots. Post-inflammatory pigmentation. Flare-ups that arrive out of nowhere. Adult acne isn’t just a teenage problem, and it’s often one of the most emotionally frustrating conditions we treat.

What we offer:
Our dermatology consultations focus on root causes — hormonal, inflammatory or lifestyle-related — and we tailor treatment to your skin’s full story. This might include prescriptions, antibiotics, medical-grade skincare, or targeted peels and facials.

We believe in results, not “cover-ups.” No one-size-fits-all plans. Just effective, joined-up care.

Patient journey: One of the reasons this clinic was founded is to treat adult acne. Read out our cofounder’s story here, and about other patients we have helped here.

3. Persistent Rosacea and Redness

Red cheeks after a glass of wine? That could be rosacea. So could that breakout around your nose and chin that never quite clears. This chronic condition is often misdiagnosed — or ignored.

What we offer:
We treat rosacea with a combination of topical or oral prescription treatments, plus optional IPL (intense pulsed light) therapy to reduce redness and visible blood vessels.

Good to know: Early treatment means better control. We also help identify and avoid triggers.

Patient journey: Getting quick results for rosacea can be lifechanging – read out our patients here, including before and after pictures. 

4. Pigmentation – From Sunspots to Melasma

Discolouration from sun damage or hormonal shifts is something we see daily. It affects skin confidence at any age — and is notoriously hard to treat without expert guidance, but so rewarding when we see the pigmentation clear in front of our eyes.

What we offer:
We combine prescription creams, targeted peels, and advanced treatments like laser or microneedling, depending on the cause and your skin tone. Your skin history and diagnosis guide the plan — always.

           Good to know: Not all pigmentation is the same. We can help you with the correct diagnosis for the most effective treatment.

5. “I Just Want a Professional to Look at It.”

Sometimes, it’s not a specific issue — it’s a sense that something’s not quite right. Maybe your skin’s changed, or you’ve got a cluster of minor concerns you want expert eyes on.

What we offer:
A dermatology consultation in London is a good place to start. You’ll see a GMC-registered doctor who’ll assess your skin thoroughly and map out your options, whether that’s medical treatment, preventative care, or onward referral. We are a friendly bunch, so please reach out and ask us questions – we’re happy to point you in the right direction, even if it is not us.

You Know Your Skin. We Know How to Treat It.

Our London clinic was founded to make expert skin care simpler — with medical and cosmetic dermatology under one roof. Whether you’re coming in for a mole check, a long-term acne plan, or a one-off consultation, you’ll leave with answers and a clear plan forward.
