Key facts

Hyperpigmentation at a glance.

The essentials, in plain English - what it is, the common patterns, and how it is treated in the UK today.

  • What it is

    Excessive melanin deposition in the skin producing darker patches, spots or diffuse areas of pigment.

  • Types

    Epidermal (superficial, dark brown), dermal (deeper, grey-blue) or mixed - the depth guides treatment.

  • Common patterns

    Post-inflammatory hyperpigmentation, melasma, solar lentigines, freckles, naevi and drug-induced pigment.

  • Who it affects

    Anyone can develop it - melasma and PIH are especially common in Fitzpatrick skin types IV to VI.

  • Foundation therapy

    Rigorous broad-spectrum SPF 50+ (ideally tinted with iron oxide) is the backbone of every treatment plan.

  • Specialist input

    Complex, resistant or dermal pigment usually needs a consultant dermatologist and skin-type appropriate laser.

Why this guide matters

A stepped plan, not a shelf of products.

Hyperpigmentation is common, treatable and - with the right ladder - usually controllable. The three points below shape everything else on this page.

  • Sun protection is the foundation

    Broad-spectrum SPF 50+, ideally tinted with iron oxide to block visible light - without this, nothing else holds.

  • Depth guides the treatment

    Epidermal pigment responds to topicals; dermal pigment usually needs a specialist plan with skin-type-appropriate laser.

  • Underlying cause matters

    Endocrine, metabolic and drug-induced pigment need the underlying trigger addressed, not just cosmetic lightening.

How the diagnosis is made

From first patch to a clear plan.

The steps a UK GP or dermatologist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    History and triggers

    A structured look at onset, sun exposure, pregnancy, contraception, hormonal changes and family history.

  2. 02

    Assessing

    Medication review

    Minocycline, hydroxychloroquine, amiodarone, antipsychotics and chemotherapy can all deposit pigment - a full drug list matters.

  3. 03

    Assessing

    Skin examination

    Pattern, distribution, colour and progression - localised patches point differently to generalised darkening.

  4. 04

    Confirming

    Wood lamp and dermatoscopy

    A Wood lamp accentuates epidermal pigment; dermal pigment is not accentuated - a simple, powerful bedside test.

  5. 05

    Confirming

    Skin biopsy if unclear

    A selective punch biopsy (see /treatments/skin-biopsy/) helps when the diagnosis or depth is uncertain.

  6. 06

    Referring

    Bloods for systemic causes

    Endocrine and iron studies where features suggest Addison disease, thyroid disease or haemochromatosis.

  7. 07

    Referring

    Specialist dermatology referral

    Melasma, dermal pigment, resistant PIH or systemic features warrant a dermatologist experienced in pigmentary disorders.

Typical timeline: a first visit to a settled plan in weeks, with results measured over months.

Symptoms

What hyperpigmentation actually looks like.

The common patterns you will see - from post-inflammatory pigment and melasma through to systemic and drug-induced discolouration.

  • Post-inflammatory pigment

    Brown patches left behind after acne (see /conditions/acne/), eczema (see /conditions/eczema-dermatitis/) or injury.

  • Melasma

    Symmetrical brown patches on the face - cheeks, forehead and upper lip - often triggered by pregnancy or the pill.

  • Solar lentigines

    Well-defined brown spots on sun-exposed skin - the hands, face and shoulders of older adults.

  • Freckles (ephelides)

    Small, tan spots that darken with sun and fade in winter - benign and typically hereditary.

  • Naevi and dysplastic moles

    Pigmented lesions with a range of appearances - persistent change deserves a dermatology opinion.

  • Drug-induced pigment

    Slate-grey to brown discolouration linked to minocycline, amiodarone, hydroxychloroquine or chemotherapy.

  • Endocrine and systemic patterns

    Generalised bronzing may suggest Addison (see /conditions/addisons-disease/) or haemochromatosis (see /conditions/hemochromatosis/).

  • Red flag - changing pigmented lesion

    Any pigmented lesion that changes in size, shape or colour needs urgent dermatology assessment to exclude melanoma.

Treatment

How hyperpigmentation is treated in the UK.

Sun protection first, layered topicals next - and specialist-led tranexamic acid, chemical peels or laser for resistant or dermal pigment.

  • Broad-spectrum SPF 50+

    Daily, all year, reapplied every two hours in sun. Tinted formulas with iron oxide also block visible light - critical in melasma.

  • Topical hydroquinone

    Hydroquinone 2 to 4% is the most-studied lightener - used in short courses under dermatology supervision to avoid ochronosis.

  • Topical retinoid

    Tretinoin accelerates cell turnover and enhances the effect of lighteners - central to most pigmentation plans.

  • Azelaic acid and vitamin C

    Well-tolerated adjuncts - anti-inflammatory, safe in pregnancy (azelaic acid) and useful for maintenance.

  • Niacinamide, kojic acid, arbutin

    Gentler lighteners layered into a routine - modest on their own, useful as part of a stacked regimen.

  • Tranexamic acid

    Topical or oral tranexamic acid can transform stubborn melasma - oral use is specialist-led with clotting-risk screening.

  • Chemical peels

    Glycolic, salicylic and mandelic acid peels (see /treatments/chemical-peel/) at appropriate strengths for the skin type.

  • Pigment-targeted laser

    Q-switched Nd:YAG, picosecond and fractional devices (see /treatments/pigment-laser/) chosen for the Fitzpatrick skin type.

Key references

Guidelines and standards we relied on.

A quiet reminder

This guide is for information, not medical advice.

Your GP or dermatologist knows your skin, medical history and skin type, and can tell you which parts apply to you. If in doubt, get seen.

  • NICE Clinical Knowledge Summaries - pigmentation disorders.

  • British Association of Dermatologists (BAD) - patient information leaflets on melasma and post-inflammatory hyperpigmentation.

  • European Academy of Dermatology and Venereology - consensus on melasma management.

  • MHRA drug safety updates on minocycline and hydroxychloroquine pigmentation.

Red flags

When pigmentation needs urgent attention.

Most hyperpigmentation is managed in the community. These are the situations that are not - and where a specialist opinion is needed.

  • Changing pigmented lesion

    Any mole or lesion that changes size, shape, colour or bleeds needs urgent dermatology assessment to exclude melanoma.

  • Generalised bronzing

    Diffuse darkening with fatigue, weight loss or salt craving raises suspicion of Addison disease - urgent GP review.

  • Iron-overload pigment

    Slate-grey generalised pigment with joint pain or diabetes may suggest haemochromatosis - ferritin and transferrin saturation help.

  • Drug-induced slate-grey change

    New pigment on long-term minocycline, amiodarone or hydroxychloroquine - review the drug and imaging where indicated.

  • Exogenous ochronosis

    Paradoxical blue-black discolouration after prolonged high-strength hydroquinone - stop the product and refer to dermatology.

  • Rapidly spreading pigment

    Rapid, unexplained pigment change - especially with systemic symptoms - deserves same-week specialist review.

  • Mucosal pigmentation with polyps

    Peri-oral and mucosal freckling with GI polyps raises Peutz-Jeghers syndrome (see /conditions/gastric-neuroendocrine-tumors/) - refer.

  • Psychological impact

    Melasma and PIH can weigh heavily on mood and confidence - please raise this early; it is a valid reason to treat.

  • Photodistributed rash

    Pigment change confined to sun-exposed areas with a rash may suggest lupus or dermatomyositis - urgent specialist review.

Living with it

A treatable condition, with a clear ladder.

Four things that make the biggest difference day to day - daily sunscreen, a simple routine, patience with topicals, and knowing when to step up to specialist treatment.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits - kept up for months - do more for pigment than a heroic week that does not last.

  1. 01 Sun

    Sunscreen is non-negotiable

    Daily broad-spectrum SPF 50+, ideally tinted with iron oxide to block visible light - the single biggest factor in preventing relapse.

  2. 02 Routine

    Keep it simple and consistent

    One retinoid at night, a lightener in the morning, and a gentle moisturiser. Layering too many actives irritates and darkens.

  3. 03 Patience

    Give it 12 to 24 weeks

    Epidermal pigment fades over months, not days. Judge progress with photos every four weeks.

  4. 04 Escalate

    Ask about lasers when stuck

    For resistant or dermal pigment, a dermatologist-led laser plan on the right device for your skin type can move things on.

Frequently asked

Everything we get asked about hyperpigmentation.

Quick answers on sun protection, hydroquinone, melasma, tranexamic acid and when to see a dermatologist.

  • What is hyperpigmentation?

    It is the excess deposition of melanin in the skin, producing darker patches, spots or diffuse discolouration. It ranges from surface-level post-inflammatory pigment after acne through to deeper dermal pigment that is harder to shift.

  • What is the difference between epidermal and dermal pigmentation?

    Epidermal pigment sits in the outer skin, appears dark brown and lifts under a Wood lamp - it usually responds well to topical lighteners. Dermal pigment sits deeper, looks grey-blue, is not accentuated by a Wood lamp, and generally needs a specialist plan including laser.

  • Why is sunscreen so important in hyperpigmentation?

    Ultraviolet and visible light both drive melanin production. Without daily broad-spectrum SPF 50+ - ideally tinted with iron oxide to block visible light - lightening treatments rarely hold, and melasma in particular relapses quickly.

  • Is hydroquinone safe to use?

    Short courses of 2 to 4% hydroquinone under dermatology supervision are highly effective. Continuous long-term use can cause exogenous ochronosis - a paradoxical blue-black darkening - so it should be cycled and never used indefinitely.

  • Can melasma be cured?

    Melasma can be very well controlled but tends to relapse with sun, hormones or heat. A long-term maintenance plan with sun protection, topicals and, where needed, oral tranexamic acid or laser gives the best chance of durable control.

  • When should I see a dermatologist?

    Consider a specialist opinion for melasma, resistant post-inflammatory pigment, dermal pigment, drug-induced pigment or any pigmented lesion that is changing. A dermatologist experienced in pigmentary disorders will match the device and drug to your skin type.
