Private Hyperpigmentation Treatment in London
Hyperpigmentation is a common skin concern where areas of skin look darker than the surrounding skin. It can develop for several reasons, including sun exposure, hormonal changes, and inflammation after acne, eczema, or injury.
Although it is usually harmless, it can be draining when the pigmentation sits on visible areas and does not shift with over-the-counter products. Many people with this skin condition feel stuck in a cycle of covering with make-up, buying brightening products, and still seeing the same patches in the mirror.
At the Thomas Clinic, our approach starts with clarity. We confirm what type of pigmentation you have (for example, melasma, post-inflammatory hyperpigmentation, or sun-induced pigmentation), and then build a plan around your skin type, your routine, and what you realistically want to achieve. From there, we can use a combination of prescription topical treatment and medical-grade skincare, with careful guidance on maintenance, because prevention is often just as important as the initial improvement.
If hyperpigmentation is affecting your confidence, we can help you move towards calmer, more even-toned skin with a plan that is evidence-based and personally tailored to you.
Dr Bjorn Thomas – Hyperpigmentation Dermatologist
Dr Björn Thomas (MBBS, PhD, MRCP) is a Consultant Dermatologist with extensive experience in private work and a background as a senior NHS dermatologist. He takes a careful, diagnosis-led approach to pigmentation concerns because different types behave differently, and treatment needs to match that.
At the Thomas Clinic, we value providing patients with clear explanations and a plan that feels realistic rather than sales-led. We also take cosmetic outcomes seriously, especially on the face, where over-treatment can sometimes worsen pigmentation rather than improve it.

If you are dealing with persistent pigmentation, a consultation is the quickest way to stop guessing. During your appointment, we will assess your skin in detail, confirm the likely diagnosis, and talk you through the options that make sense for your type of hyperpigmentation.
Cosmetic pigmentation concerns are not always prioritised within NHS pathways, so many people choose a private assessment for faster access and a more personalised plan.
Hyperpigmentation can be challenging, but it is usually very manageable with the right strategy. The key is matching the approach to the correct pigment type and depth, then backing it up with consistent sun protection and maintenance.
It is also worth saying that not all pigmentation needs active treatment. Where pigmentation has followed inflammation, such as after acne or eczema, much of it can fade on its own once the underlying inflammation is controlled and the skin is protected from the sun, though this can take months, and the more superficial the pigment, the better it tends to settle.
Deeper pigment, and conditions such as melasma, are less likely to clear without a plan. Part of the assessment is working out which kind you have, so you are not treating something that would settle anyway, or under-treating something that will not.
Below is an overview of how we approach treatment at the Thomas Clinic…
Hyperpigmentation Pre-treatment Assessment
Your first step is a thorough dermatology assessment. A careful history is taken, including when the pigmentation started, whether it changes with sun exposure or hormones, any previous skin inflammation (such as acne or eczema), medications, and what you have already tried.
We then examine the skin closely. A Wood’s lamp is useful for showing the true extent of pigment, including areas not obvious to the naked eye, while dermoscopy can help judge the depth and pattern of pigment and, importantly, make sure nothing concerning is being missed. The aim is to confirm the diagnosis and the type of pigmentation, because different types behave very differently and need different management.
You will have time to ask questions, discuss what you want to improve, and understand what is realistic. That tends to remove a lot of the anxiety people feel when pigmentation has been a concern for months or years.
Hyperpigmentation Treatment Methods
Treatment is tailored to your specific type of pigmentation, your skin characteristics, and your lifestyle.
Topical Treatments
Prescription topical treatments are often the first step. They work by reducing pigment production and supporting healthy skin turnover, and the right choice depends on your pigment type, skin sensitivity, and how your skin has reacted to treatments before. Some are used in defined courses rather than continuously, which is something we plan together, so results are protected and side effects avoided. Medical-grade skincare and antioxidants can support tone and protect against UV-related darkening as part of a wider routine.
We will discuss the specific prescription and skincare options suited to your skin at your consultation.
Cosmetic Procedures (Not currently offered at the Thomas Clinic)
Some people ask about procedures for faster results. We are happy to explain these options and advise whether they are appropriate for your skin and pigment type, but they are not currently offered directly through the Thomas Clinic.
Examples include:
- Chemical peels: Superficial peels (for example, glycolic or salicylic acid) to exfoliate and improve tone.
- Microneedling: Supports skin renewal and can improve absorption of topical treatments.
Laser Treatments
Lasers have a role in selected types of pigmentation, but they are not a blanket solution, and the wrong laser or settings can make pigmentation worse.
My approach is deliberately selective. For discrete sun-induced pigmentation such as lentigines (sunspots), laser or related light-based treatment can work well.
For melasma, and pigmentation that follows inflammation or rashes, we do not currently use lasers as a treatment. Some practitioners do, but these types are easily aggravated by laser, and in my view, they are usually better managed with a careful topical and prevention-led plan.
If a laser is appropriate for your pigment type, we will talk you through expected outcomes, risks, downtime, and how to reduce the chance of rebound pigmentation.
Cryotherapy
For isolated sun-induced pigmentation such as lentigines (sunspots), cryotherapy can be a useful and straightforward option.
As with laser, it is suited to discrete, well-defined spots rather than melasma or pigmentation that follows inflammation, where it would not be appropriate. If cryotherapy is suitable for your pigment type, we will explain what to expect, including the small risk of the treated area healing slightly lighter or darker than the surrounding skin, a risk that needs particular care in darker skin types.
Hyperpigmentation Aftercare Hints and Tips
Aftercare is where many results are either protected or lost. The most important principle is simple: pigment darkens with inflammation and UV exposure, so the goal is to keep skin calm and protected.
Strict Sun Protection
- Use broad-spectrum sunscreen daily, ideally SPF 30+ with strong UVA protection.
- Reapply when outdoors, especially during brighter months.
- Use shade and protective clothing during peak UV hours.
- Avoid tanning beds and intentional sun exposure.
Gentle Cleansing and Hydration
- Cleanse with a mild, soap-free cleanser and lukewarm water.
- Moisturise consistently using fragrance-free products that suit your skin.
Avoid Skin Irritation
- Do not pick, peel, or scrub flaking skin.
- Pause strong actives (retinoids, exfoliating acids, benzoyl peroxide) until skin has settled, unless advised otherwise.
Reduce Inflammation and Swelling
- Use cool compresses if the skin feels hot or irritated.
- In selected cases, we may advise a short, controlled course of anti-inflammatory treatment.
Long-Term Maintenance
- Continue daily sun protection long-term.
- Use maintenance brightening ingredients that suit your skin, such as vitamin C.
- Consider periodic review if pigmentation is recurring, or if triggers are difficult to control.
What Typically Causes Hyperpigmentation?
Hyperpigmentation happens when the skin produces excess melanin, usually as a response to UV exposure or inflammation.
Common causes include:
- Sun exposure (UV rays): Cumulative UV drives sunspots, freckles, and worsening of existing pigmentation.
- Hormonal changes: Pregnancy, contraception, and hormone therapy can trigger melasma.
- Post-inflammatory pigmentation: Marks left behind after acne, eczema, irritation, or injury.
- Genetic tendency: Some skin types are more prone to pigment overproduction.
- Ageing and cumulative exposure: Lentigines (sunspots) become more common over time.
Most hyperpigmentation is benign, but if pigmentation is new, unusual, changing, or looks different from your usual pattern, it should be assessed properly. If there is any concern about a lesion, we may recommend an appropriate review rather than treating it cosmetically.
We conduct skin cancer screening at either of our 3 London clinic locations:
Where Does Hyperpigmentation Develop?
Hyperpigmentation can appear nearly anywhere, but it often shows up in areas exposed to the sun or areas that have been inflamed previously:
- Face: Cheeks, forehead, upper lip, chin.
- Neck and chest: Common with cumulative sun exposure.
- Hands and arms: Sunspots and freckles are common here.
- Back and shoulders: often affected by sun-related pigmentation or post-acne marks.
Because different body sites heal differently, and different skin types have different risks of rebound pigment, we tailor treatment to both the location and your skin’s tendency to mark.
Patient Satisfaction & Hyperpigmentation Treatment Results
When pigmentation improves, patients often describe feeling less reliant on make-up, less self-conscious in photos, and less distracted by their skin day to day.
If you want to see examples of typical outcomes, before-and-after imagery can be discussed during a private consultation, with a realistic context around what was used and how long the improvement took.

Hyperpigmentation Frequently Asked Questions
Can you permanently fix hyperpigmentation?
Hyperpigmentation can often be significantly improved, but some forms (especially melasma and recurrent PIH) can return if triggers persist. The goal is usually long-term control: visible improvement plus maintenance, supported by daily sun protection and a routine that avoids irritation.
Is vitamin C good for hyperpigmentation?
Vitamin C can be a helpful part of a routine. It supports brighter tone over time and provides antioxidant protection, which is useful because UV exposure can worsen pigmentation. It tends to work best as part of a wider plan rather than as a stand-alone “fix”.
How many years does it take for hyperpigmentation to fade?
It depends on the cause and depth of pigment. Mild post-inflammatory marks may fade over months, while deeper PIH can persist longer. Melasma can fluctuate over time and often needs ongoing management. Sun-induced spots usually do not fade fully without treatment, and they can darken again with ongoing UV exposure.
Does vitamin B12 deficiency cause hyperpigmentation?
Vitamin B12 deficiency can be associated with skin pigmentation changes in some cases, although it is not a common cause of facial hyperpigmentation. If you develop unexplained pigmentation alongside symptoms such as fatigue, mouth ulcers, or neurological symptoms (for example, tingling), it is sensible to speak to a clinician about whether blood tests are appropriate.
