Melasma: Why Pigmentation Changes and What Treatment Can Achieve
Understand melasma assessment, sun and visible-light protection, treatment limitations and questions about recurrence.
Melasma can be frustrating because pigmentation may improve and then become more noticeable again. A useful treatment discussion starts with confirming what the patches are, understanding possible triggers and deciding what a worthwhile improvement would mean for you.
This guide concerns adults with suspected or diagnosed melasma. It does not assume that every dark patch on the face has the same cause, or that pigmentation needs correcting to make skin acceptable. Choosing observation, camouflage or treatment is a personal decision.
Key takeaways
- Melasma usually causes flat brown or grey-brown patches, often on the face.
- Sunlight, hormonal circumstances and individual susceptibility can contribute.
- Sun protection is central; visible-light protection may also matter.
- Improvement is possible, but recurrence and incomplete clearance should be discussed.
- A peel or laser is not an automatic next step for every patch.

Confirm the diagnosis before choosing a treatment
The British Association of Dermatologists’ melasma leaflet describes pigmentation that is flat and generally not itchy or painful. It is more common in women and people of colour, although others can be affected. Diagnosed melasma is not contagious or cancerous; that reassurance should not be used to identify an unexamined lesion yourself.
Explain when the change started, whether it is symmetrical and whether individual areas are changing differently. Tell the clinician about associated symptoms and previous treatments. If a particular spot looks different from the surrounding patches, point it out separately rather than treating the whole face as one cosmetic concern.
The American Academy of Dermatology describes examination, sometimes assisted by a dermatoscope or Wood’s lamp, with occasional biopsy when another diagnosis needs excluding. Ask what supports the diagnosis and whether any uncertainty changes the treatment plan.
Understand triggers without blaming yourself
BAD identifies ultraviolet exposure, pregnancy and hormonal medicines among relevant factors. A medication history is therefore useful, but it is not an instruction to stop contraception or another prescribed treatment. Discuss the timing and alternatives with the prescriber. Melasma can persist even when an apparent trigger changes, so a single explanation may not predict its course.
Make a brief timeline of pregnancy, medication changes, sunny holidays and skincare reactions. Include what you know rather than guessing what caused the pigmentation. An appointment is more productive when the clinician can distinguish observed events from assumptions made after reading product advertising.
Sun protection and the visible-light question
The AAD’s melasma self-care advice recommends shade, protective clothing and broad-spectrum, water-resistant sunscreen with SPF 30 or higher. It also recommends a tinted sunscreen containing iron oxide for visible-light protection. The relevant product must provide the stated protection; a foundation shade alone does not tell you what it protects against.
In a 2014 randomised trial, 68 participants received either ultraviolet-plus-visible-light sunscreen or ultraviolet-only sunscreen for eight weeks, alongside 4% hydroquinone in both groups. Sixty-one completed the study. The visible-light-protective group had better results on the measured pigmentation outcomes. This supports that combination under the study conditions; it does not show that every tinted cosmetic is equivalent or that sunscreen alone produced those treatment results.
Ask for help finding a shade and texture you can use comfortably. Note whether a product stings, pills over another preparation or leaves a finish that discourages application. These practical issues deserve attention because a plan that stays in a drawer cannot serve its intended purpose.
What treatment can reasonably aim to do
The AAD describes individual plans combining protection with topical medicines and, sometimes, procedures. Options discussed in specialist care may include hydroquinone-containing preparations, azelaic acid or prescription combinations. The selection, duration and review depend on the individual; ingredient names are not a shopping list for unsupervised mixing.
Ask which change is expected, how it will be assessed and what maintenance may involve. Specify whether your goal is less contrast, easier camouflage or improvement in one particular area. “Clear skin” can mean different things to a practitioner and a patient, so defining the aim helps avoid disappointment later.
| Decision | Ask | Avoid assuming |
|---|---|---|
| Diagnosis | What makes this melasma rather than another pigment change? | Every dark mark needs the same treatment |
| Topical medicine | Where, how long and when will it be reviewed? | A stronger or longer course is automatically better |
| Procedure | What added benefit and pigment risks apply to me? | A device guarantees permanent clearance |
| Maintenance | What happens if pigmentation returns? | Recurrence means you failed to follow the plan |
| Cost | What is included in assessment and follow-up? | The first treatment price covers the whole course |
Be cautious about escalating to peels or lasers
BAD warns that procedures can worsen pigmentation, cause lighter patches or produce other complications. Expertise matters, particularly when treating skin prone to pigment change. A decision to use a procedure should explain why it is suitable for this diagnosis and skin, not simply offer the clinic’s available machine.
Read our chemical peel guide and laser resurfacing explainer if either is proposed. Bring the recommendation back to the melasma plan: what does it add, what could go wrong and who will manage an unwanted pigment change?
Keep skincare comfortable and the plan reviewable
AAD advises gentle, fragrance-free skincare and notes that irritation can darken pigmentation. Avoid interpreting burning as evidence that a product is removing pigment effectively. Keep the packaging and report a reaction. Our contact dermatitis guide explains why irritation and allergy cannot be distinguished by a marketing label.
Establish the diagnosis and describe the change you want addressed.
Agree protection, any treatment, costs and signs of intolerance.
Compare progress consistently and discuss maintenance or alternatives.
For review photographs, keep lighting, camera distance and makeup use similar. Record product changes alongside the pictures. Differences in exposure or filters can make a treatment seem more or less effective than it is. A useful record supports a conversation; it should not become a daily demand to scrutinise every patch.
If pregnancy, breastfeeding or plans to conceive are relevant, raise them before any medicine or procedure is selected. Ask for advice specific to the proposed product. If the emotional impact is the main concern, say so: reassurance and practical camouflage may be worthwhile even when you decide against active treatment.
Common questions
Is every dark facial patch melasma?
No. Several conditions can alter pigmentation. Obtain an assessment before using a brightening product or procedure on a new or uncertain mark.
Can men develop melasma?
Yes, although it is more common in women. The diagnosis depends on the clinical assessment, not a label that restricts the condition to pregnancy.
Should I stop hormonal contraception myself?
No. Discuss the possible connection and alternatives with the prescriber. A timeline may be useful, but it does not by itself establish causation.
Does any tinted makeup provide the same protection?
No. Check sunscreen protection and ingredients rather than assuming colour is enough. The cited trial tested specific sunscreens alongside another treatment.
Is a laser guaranteed to clear melasma?
No. Ask about expected benefit, recurrence and the possibility of darker or lighter patches. Device availability does not establish suitability.
Does stronger irritation mean better results?
No. Burning or a new rash deserves attention. Irritation can undermine a pigmentation plan, so report it rather than increasing applications.
Can I choose camouflage instead of treatment?
Yes. The choice depends on your priorities. Ask about comfortable products and application that fit around sun protection and any prescribed care.
What should a follow-up appointment cover?
Review tolerability, consistent observations, whether the agreed goal is being approached and what comes next. Clarify maintenance rather than assuming treatment continues indefinitely.
