Hyperpigmentation is one of the most common skin concerns in deeper skin tones, and also one of the most frustrating. Dark marks and uneven patches can linger long after the original trigger has gone, and treating them carelessly can make them worse. In skin of colour, the right approach is rarely the most aggressive one.
At our Mayfair clinic, consultant dermatologist Dr Jinah Yoo has particular experience treating pigmentation across a wide range of skin types. This guide explains why hyperpigmentation behaves differently in skin of colour, what causes it, and how it can be treated safely and effectively.
What Is Hyperpigmentation?
Hyperpigmentation describes areas of skin that become darker than the surrounding tone. It happens when the skin produces excess melanin, the pigment responsible for skin colour, in response to a trigger such as inflammation, sun exposure or hormonal change.
In darker skin tones, melanocytes, the cells that produce melanin, are naturally more active and more reactive. This is part of what gives richly pigmented skin its tone, but it also means the skin is quicker to produce extra pigment when it is irritated or injured.
Why Skin of Colour Is More Prone to Hyperpigmentation
The same biology that protects darker skin from some sun damage also makes it more reactive to inflammation. When melanin-rich skin experiences trauma, breakouts or an overly harsh treatment, it often responds by depositing extra pigment in the affected area.
This is why hyperpigmentation tends to be more visible, more stubborn and longer-lasting in skin of colour. It is also why treatment has to be approached with care, because the wrong intervention can trigger exactly the response you are trying to settle.
Common Causes in Deeper Skin Tones
Several triggers commonly lead to hyperpigmentation:
- Post-inflammatory hyperpigmentation – marks left after acne, eczema, ingrown hairs or skin trauma. This is the most common type in skin of colour.
- Melasma – larger, often symmetrical patches linked to hormones and sun exposure.
- Sun exposure – ultraviolet light deepens existing pigmentation and triggers new marks.
- Skin trauma – picking, harsh scrubbing or aggressive treatments can all leave lasting pigment.
Because acne is such a frequent trigger, treating the underlying acne alongside the pigmentation is often part of a lasting solution. The same is true for post-inflammatory hyperpigmentation, where calming the inflammation matters as much as fading the marks.
Why the Wrong Treatment Can Make It Worse
This is the single most important point for skin of colour. Many lasers, strong peels and aggressive treatments were designed with lighter skin in mind. Used on deeper skin tones, they can cause burns, patchy lightening or, more commonly, a rebound of even darker pigmentation.
For this reason, a proper assessment of your skin type and the cause of your pigmentation should always come before treatment. Devices and strengths need to be selected specifically for melanin-rich skin, and treatment is usually built up gradually rather than rushed.
How Hyperpigmentation Is Treated Safely
There is no single answer, but a careful, layered approach gives the most reliable results in skin of colour:
- Prescription topical treatments – ingredients that reduce melanin production and support gentle skin renewal.
- Gentle chemical peels – carefully chosen and built up slowly to improve tone without provoking pigment.
- Suitable laser and light treatments – devices such as Hollywood Spectra laser toning, used at settings appropriate for deeper skin tones.
- Daily sun protection – essential, because without it pigmentation will keep returning regardless of treatment.
The emphasis throughout is on consistency and patience. Pigment-prone skin responds far better to a steady, gradual plan than to intensive one-off treatments. Where laser or energy-based treatment is considered, a test patch is often used first to check how your skin responds before treating a wider area, which adds an extra layer of safety in deeper skin tones.
What to Expect
Treatment starts with a consultation, where your skin type is assessed and the cause of your hyperpigmentation identified. From there, a tailored plan is built, often combining topical treatment with in-clinic sessions and a strong focus on sun protection.
Improvement is gradual and usually measured over weeks to months, particularly for post-inflammatory marks and melasma. Your dermatologist will give you realistic timelines and explain how to maintain your results once your tone has evened out.
Risks and Realistic Expectations
Treating hyperpigmentation in skin of colour is safe when done correctly, but a few points are worth understanding:
- Rebound pigmentation – the main risk if treatment is too aggressive, which is why careful selection matters.
- Recurrence – melasma in particular can return, especially with sun exposure or hormonal change.
- Gradual results – meaningful change takes time and consistency rather than a single session.
No responsible clinic can promise permanent removal, because new pigment can always form. The goal is clear, well-maintained improvement.
The Dr Jinah Yoo Approach
Skin of colour deserves treatment from someone who understands how it behaves. As a GMC-registered consultant dermatologist, Dr Jinah Yoo treats pigmentation with this firmly in mind:
- Your skin type and the cause of pigmentation are assessed before any treatment.
- Devices and strengths are chosen specifically for melanin-rich skin.
- Treatment is layered gradually to avoid triggering rebound pigment.
- Underlying causes, such as acne, are addressed alongside the marks themselves.

Frequently Asked Questions
Why is hyperpigmentation worse in darker skin?
Darker skin has more active melanocytes, so it produces extra pigment more readily in response to inflammation, injury or sun. This makes hyperpigmentation more visible and longer-lasting in skin of colour, and it is why treatment needs to be chosen carefully.
Is laser treatment safe for skin of colour?
Laser can be safe and effective in deeper skin tones, but only when the right device and settings are used and the treatment is carried out by an experienced practitioner. The wrong laser can cause burns or worsen pigmentation, which is why assessment and suitable device selection are essential first.
How is hyperpigmentation different from melasma?
Melasma is a specific type of pigmentation, usually appearing as larger symmetrical patches linked to hormones and sun. General hyperpigmentation includes other causes too, such as post-inflammatory marks from acne. You can read more about melasma and how it is managed.
How long does hyperpigmentation take to fade?
It depends on the cause and depth. Superficial marks can improve over several weeks, while deeper post-inflammatory pigmentation and melasma often take months of consistent treatment. Daily sun protection has a major effect on how well and how quickly results show.
Can hyperpigmentation be cured permanently?
Hyperpigmentation can be significantly reduced, but it cannot be guaranteed never to return, because new pigment can form with future triggers. Well-maintained results, supported by sun protection and a suitable routine, are a realistic and achievable goal.
