08 Aug Melasma Treatment Singapore | Why It Comes Back and Where Pico Laser Fits
By Dr Rachel Ho | Aesthetic Doctor, Founder, The Skin Longevity Clinic, Singapore
Melasma is a chronic pigment condition that is controlled rather than permanently removed. Effective melasma treatment in Singapore combines strict protection from ultraviolet and visible light, prescription topical treatment, careful trigger management and, in selected stable cases, gentle laser such as low energy Pico toning. Any clinic promising to erase melasma with a laser package alone is describing a treatment plan that commonly ends in disappointment or rebound darkening.
What is melasma?
Melasma appears as symmetrical brown to grey brown patches, most often across the cheeks, forehead, upper lip, nose and jawline. It is far more common in women and in skin of colour, including the Fitzpatrick type III to V skin tones typical in Singapore. The pigment may sit in the epidermis, the dermis or both, and the deeper the pigment, the slower the response to treatment.
Melasma is not just excess melanin. Research points to overactive melanocytes, changes in the skin’s support structures, increased blood vessel activity and a barrier that is easily irritated. That combination explains two clinical facts. Melasma responds to treatment, and melasma relapses when treatment stops or triggers return.
What melasma actually involves under the skin
Melasma is more complicated than excess pigment sitting on the surface. Research now shows it involves the pigment cells, the surrounding skin cells, the fibroblasts of the deeper skin, mast cells and the small blood vessels of the dermis, with both inflammation and increased blood vessel activity feeding the pigment. This is why an irritated or overheated face flares so readily, and why treatment aims to calm and protect the skin rather than attack it.
Doctors describe melasma in three common patterns. The centrofacial pattern covers the forehead, cheeks, upper lip, nose and chin and is the most common. The malar pattern sits over the cheeks and nose. The mandibular pattern follows the jawline. Examining the pigment under a specialised lamp can also suggest whether it sits mainly in the upper skin, the deeper skin or both, which helps set realistic expectations, since deeper pigment fades more slowly.
What triggers melasma?
- Ultraviolet exposure, which stimulates melanocytes directly
- Visible light, especially high energy blue light, which darkens melasma even through window glass
- Heat, relevant in Singapore’s climate, hot kitchens, saunas and intense outdoor exercise
- Hormones, including pregnancy, oral contraceptive pills and hormone therapy
- Genetics, with family history strongly predicting susceptibility
- Skin irritation and inflammation, including harsh scrubs and overly aggressive treatments
- Certain medications and fragranced products in some individuals
Most patients have several triggers at once, which is why single tool treatment plans underperform. A structured overview of pigment conditions and how they differ appears in our pillar guide to pigmentation treatment in Singapore, and this detailed review of hyperpigmentation disorders provides useful medical background.
Why melasma keeps coming back
Melasma relapses because its drivers persist. Melanocytes in melasma prone skin remain primed to overproduce pigment, so any new dose of ultraviolet light, visible light, heat or hormonal change can reactivate patches that had faded. Stopping sunscreen after clearance, a beach holiday, a change in contraception or a stretch of outdoor training can each bring melasma back.
This is not treatment failure. It is the nature of the condition, and it changes the goal of treatment. The aim is long term control with the least aggressive effective plan, not a one time removal.
The foundation, sun protection done properly
Every effective melasma plan is built on photoprotection.
- Broad spectrum sunscreen with high protection worn every day, indoors and outdoors, reapplied when exposed
- Tinted sunscreen containing iron oxides, which blocks the visible light that plain sunscreens miss and which matters specifically for melasma
- Hats, shade and sensible timing of outdoor activity
- Heat awareness, since flushing and overheating can aggravate melasma even without sun
Finding a sunscreen pleasant enough for daily wear is half the battle. Independent texture and formula reviews such as this sunscreen review guide and this round up of current sunscreen options can help you shortlist.
Topical and oral treatments
Prescription topicals do the daily work of suppressing pigment production. Depending on your skin, a doctor may use hydroquinone in supervised courses, retinoids, azelaic acid, cysteamine, kojic acid, alpha arbutin, niacinamide or vitamin C, often in rotation to balance efficacy against irritation. Because an irritated barrier worsens melasma, gentle formulation and moisturiser support matter as much as the active ingredients. Practical guidance on lightening ingredients is covered in this article on skincare for pigmentation.
Tranexamic acid deserves specific mention. Used topically or orally where medically appropriate, it calms the interaction between melanocytes and blood vessels that drives melasma, and it has become a valuable option for stubborn cases under medical supervision. A detailed explanation is available in this review of tranexamic acid for hyperpigmentation.
When it is done correctly, laser for melasma is very effective. Under my protocol, which combines gentle laser with a chemical peel to exfoliate the superficial layers of the skin, clearance of around 80 to 90 percent is a common outcome. The key word is correctly, because melasma generally likes lower settings, and pushing energy too hard is what turns a treatable condition into a worse one.
Where Pico laser fits in melasma
Laser is an adjunct in melasma, never the foundation. Used correctly, low energy Pico laser toning can fragment existing pigment and speed visible improvement in melasma that is already stabilised with photoprotection and topicals. Used incorrectly, laser heat inflames melasma and triggers rebound pigmentation that is worse than the starting point.
Principles that keep laser safe in melasma include the following.
- Stabilise first. Active, rapidly darkening melasma is treated medically before any laser.
- Gentle settings. Low fluence toning, conservative endpoints and no chasing of instant clearance.
- Adequate spacing. Skin needs time to clear pigment and recover between sessions.
- Combination thinking. Laser accompanies sunscreen, topicals and trigger control, it does not replace them. Peels such as those on our chemical peel page may also play a role in selected plans.
- Honest monitoring. If skin darkens after a session, the plan is reassessed rather than repeated.
The differences between laser types for pigment are compared in Pico laser vs Q-switched laser vs IPL vs chemical peel, and aftercare that protects results is covered in our Pico laser aftercare guide.
Newer options being studied for melasma
The toolkit for melasma keeps growing, and several options are supported by encouraging evidence when used within a proper plan.
Tranexamic acid works by calming the pathway that links inflammation and blood vessel activity to pigment production, which is why it suits a condition driven by those very factors. Both oral and topical forms have been found effective for melasma, performing comparably to established lightening creams while causing fewer side effects and fewer relapses. Lower doses of the oral form have been found to work as well as higher doses, so more is not better. Pairing tranexamic acid with niacinamide adds a complementary action, since niacinamide reduces the transfer of pigment into surface skin cells, calms inflammation and supports the skin barrier. Advanced delivery systems that carry tranexamic acid more efficiently into the skin can achieve the same benefit at lower concentrations.
Delivery can be enhanced further. Local dynamic micro-massage, an ultrasound based treatment offered as the LDM facial, can help topical ingredients such as tranexamic acid penetrate more effectively while supporting drainage and calming the skin.
Gentle peels have a solid record too. Chemical peels are safe and effective for melasma, with glycolic acid the most established option, and newer bio-revitalisation peels of the PRX-Plus type combine acid with hydrogen peroxide and kojic acid so they can revitalise the deeper skin and lighten pigment without the frosting and downtime of stronger peels.
Regenerative approaches are emerging as well. Exosome treatments use tiny vesicles that carry signalling molecules between cells and are being studied for melasma, where they may help settle the inflammation and blood vessel activity that keep pigment persistent. This field is promising and still maturing, so it is best used thoughtfully alongside proven measures rather than in place of them.
Melasma versus conditions that mimic it
Melasma is commonly confused with sun spots, PIH and Hori’s naevus, and the treatments differ meaningfully. Grey brown symmetrical patches over the cheekbones that have not responded to creams may be dermal pigment rather than melasma, discussed in our article on stubborn pigmentation in Asian skin. Discrete darker spots that respond quickly to laser behave more like solar lentigines, covered in freckles, sun spots and age spots. Getting this differentiation right is the main reason to have a doctor diagnose your pigment before treating it.
What a realistic melasma journey looks like
Melasma treatments at a glance
| Melasma phase | Focus | What you can expect |
|---|---|---|
| Stabilisation | Photoprotection, barrier repair, prescription topicals, trigger review | Darkening stops, patches begin to soften |
| Improvement | Continued topicals, possible tranexamic acid, gentle Pico toning if suitable | Gradual visible lightening over weeks to months |
| Maintenance | Daily sunscreen, maintenance topicals, spaced toning sessions if needed | Control held, flare ups addressed early |
| Relapse management | Early review when patches darken | Small adjustments rather than starting over |
Pregnancy deserves its own note. Melasma often appears or worsens during pregnancy, and many actives and elective procedures are deferred until after delivery and breastfeeding. Gentle skincare and diligent photoprotection remain safe and worthwhile during this period, with fuller treatment resumed later under medical guidance.
A daily routine that supports melasma control
Melasma outcomes are decided in bathrooms as much as clinics, so the daily routine deserves the same attention as any procedure.
In the morning, a gentle cleanse without scrubbing, any prescribed lightening treatment, moisturiser if your skin runs dry, then a generous layer of tinted broad spectrum sunscreen. Sunscreen is reapplied before extended outdoor time, after heavy sweating and during long days near windows, since visible light passes through glass.
In the evening, thorough but gentle cleansing, the prescribed active for that phase of your plan, and moisturiser to keep the barrier resilient. Irritation is the enemy, so if any active stings persistently or leaves the skin flaky and red, report it at review rather than pushing through, because an inflamed barrier feeds melasma.
Through the day, manage heat where you can. Shade over direct sun, air conditioned workouts over midday runs, and a hat that actually casts shadow on the cheeks rather than a token cap. None of these steps is dramatic. Together they are the difference between melasma that is quietly held and melasma that returns every time treatment pauses.
What to ask your doctor about melasma
- Is this definitely melasma, or could there be coexisting Hori’s naevus, sun spots or PIH?
- Is my melasma epidermal, dermal or mixed, and how does that change my plan?
- Which topicals will I use, in what order, and for how long?
- Is tranexamic acid appropriate for me, and in which form?
- Is my melasma stable enough to consider laser at all right now?
- What is my maintenance plan once the pigment fades, and what will it cost per year?
- What should I do at the first sign of a flare?
Melasma by location, cheeks, upper lip and forehead
Location changes both the differential diagnosis and the plan. Cheek melasma is the classic presentation, and it is also where Hori’s naevus and sun spots overlap most, so mixed pigment is common there. Upper lip melasma is notoriously persistent, sits on thin sensitive skin that tolerates less aggressive treatment, and is easily mistaken for a shadow or post waxing PIH, so patience and gentle methods rule that zone. Forehead and hairline melasma often tracks with heat and outdoor exercise habits, and it hides under fringes that trap heat against the skin. Mapping which zones are involved, and which mimics are mixed in, is part of why an examination beats a photo diagnosis, a theme expanded in our article on stubborn pigmentation in Asian skin.
Frequently asked questions
Can melasma be cured or only controlled?
Controlled. Treatment can fade patches substantially and maintenance can keep skin clear, but the tendency to form melasma remains, which is why sun protection never really retires.
Can Pico laser remove melasma permanently?
No laser removes melasma permanently. Gentle Pico toning can accelerate improvement in stabilised melasma as part of a combination plan, and maintenance protects the result.
Can laser make melasma worse?
Yes. Excessive energy, overly frequent sessions or lasering unstable melasma can cause rebound darkening. Choose a doctor who is willing to slow down or say no to laser.
Why did my melasma get darker after laser?
Most commonly because the melasma was not stable, the settings were too aggressive, or sun protection lapsed afterwards. A post laser flare should prompt reassessment of the whole plan, not a stronger session.
Is melasma hormonal?
Hormones are one major driver among several. Pregnancy and oral contraceptives commonly trigger it, but sun, heat, visible light and genetics contribute in nearly every case.
Is melasma dangerous?
No, melasma is a cosmetic and quality of life concern rather than a medical danger. Its impact on confidence is real, which is exactly why it deserves competent treatment rather than either dismissal or overtreatment.
Can melasma be treated during pregnancy?
Gentle skincare, barrier support and diligent photoprotection are the safe pillars during pregnancy and breastfeeding. Most prescription actives and elective procedures wait until afterwards, and pregnancy melasma often improves on its own after delivery, so restraint frequently pays twice.
Does diet or stress affect melasma?
Neither is a primary driver on current evidence, though anything that shifts hormones or increases skin inflammation can plausibly nudge a reactive condition. The high yield levers remain light, heat, hormones and skin irritation, so effort spent there returns far more than dietary experiments.
What sunscreen is best after pigmentation laser and for melasma?
A broad spectrum, high protection sunscreen you will genuinely wear daily, ideally tinted with iron oxides for visible light protection when melasma is the concern. Reapplication during the day matters as much as the starting choice.
Start with stability, not intensity
Melasma rewards patience and punishes aggression. If your pigmentation keeps returning or has darkened after previous treatments, book a consultation at The Skin Longevity Clinic near Orchard Road. We will confirm whether your pigment is melasma, build the foundation properly and use laser only where it genuinely helps.
