Pigmentation & Melasma Treatment in Singapore
Brown spots are not one diagnosis. Melasma, freckles, solar lentigines, post-inflammatory hyperpigmentation and some moles can look similar but behave very differently. Treatment at Aquila Medical Center starts by identifying the likely cause, pigment depth, skin tone and previous treatment response before choosing laser, light, topical or peel-based options.
The single most expensive mistake in pigmentation treatment is having the wrong diagnosis lasered. Melasma treated as if it were sunspots does not just fail — it frequently comes back worse than it started.
Results vary. Melasma and PIH can recur, and overly aggressive treatment can sometimes worsen pigmentation — especially in skin that pigments easily.

Quick answer
The best pigmentation treatment depends on what the pigment actually is
Superficial sunspots and freckles may respond well to pigment-targeting light or laser. Melasma usually needs long-term control of triggers and topical therapy, with procedures used cautiously. PIH often improves best when the original inflammation — such as acne, eczema or irritation — is controlled first. A changing or atypical pigmented lesion should be medically assessed before cosmetic laser treatment.
Solar lentigines & freckles
Usually discrete brown macules driven by cumulative UV exposure or genetics. Selected pigment lasers or BBL/IPL may be useful when the diagnosis is clear.
Melasma
Often symmetrical facial pigmentation influenced by UV, visible light, hormones, genetics and heat. It is usually managed rather than permanently removed.
Post-inflammatory hyperpigmentation
Dark marks after acne, dermatitis, injury or procedures. PIH is especially common in darker skin tones and can worsen with repeated irritation.
Moles & atypical lesions
New, changing, irregular, bleeding or unusual lesions may require dermoscopic assessment, biopsy or specialist review instead of cosmetic laser.
| What you are seeing | Likely diagnosis | What usually helps |
|---|---|---|
| Discrete, well-defined brown spots on sun-exposed areas, appearing gradually with age | Solar lentigines | Pigment-targeting laser or light often works well. The clearest indication for a device. |
| Small scattered light-brown macules, present since childhood, darker after sun | Freckles | Respond to light and laser, but recur reliably without sun protection. |
| Symmetrical brownish patches across cheeks, forehead or upper lip, worse in sun and heat | Melasma | Photoprotection and topical therapy first. Devices cautiously if at all. |
| Flat brown or grey marks exactly where a spot, rash or injury was | Post-inflammatory hyperpigmentation | Treat the cause. Many fade on their own over months. |
| Speckled blue-grey or brownish spots over both cheekbones, often appearing in adulthood | Possible Hori's naevus (ABNOM) | Behaves differently from melasma — see below. Frequently misdiagnosed. |
| A single lesion that is new, changing, irregular, bleeding or unlike your others | Needs diagnosis | Medical assessment before any cosmetic treatment. |
Depth matters
Why the same brown spot can respond very differently
Melanin may be concentrated mainly in the epidermis, sit deeper within the dermis, or be mixed across layers. Superficial pigment is often more responsive to targeted energy. Dermal pigment is harder to clear and can carry a greater risk of prolonged PIH after aggressive treatment.
Melasma adds another layer of complexity because it is biologically active and influenced by vascular, hormonal and inflammatory signals. A stronger laser is therefore not automatically a better melasma treatment.
Colour offers a rough clue you can observe yourself. Pigment sitting superficially tends to look brown and relatively well defined. Pigment sitting deeper often appears greyish, bluish or muddy, with less distinct edges — because light scattering through the overlying tissue changes how the colour reads. It is not diagnostic on its own, but a greyish cast is a reasonable reason to expect slower, less complete improvement.

Commonly missed
The diagnosis most often confused with melasma
Hori's naevus, also called acquired bilateral naevus of Ota-like macules, is common in East and Southeast Asian skin and is frequently treated for years as though it were melasma. Getting this distinction right changes the treatment entirely.
How it differs
Typically speckled rather than a smooth patch, often blue-grey rather than brown, concentrated over the cheekbones, and commonly appearing in adulthood. The pigment sits deep in the dermis.
Why it matters
Topical lightening agents that help melasma do little for it, because they cannot reach dermal pigment. Patients often conclude their skincare has failed when the diagnosis was simply wrong.
The good news
Unlike melasma, it often responds well to appropriately selected pigment laser and does not carry the same rebound tendency — so accurate diagnosis can convert years of frustration into a treatable problem.
Treatment planning
How pigmentation treatment is selected
No single device treats every pigment problem. A plan may combine daily photoprotection, prescription skincare and carefully selected procedures, with intensity based on diagnosis and skin type.
Photoprotection & trigger control
Broad-spectrum sunscreen is foundational. For melasma, visible-light protection using tinted or iron-oxide products can be useful. Heat, repeated irritation and uncontrolled acne or dermatitis may also need attention.
Topical treatment
Depending on diagnosis, options may include hydroquinone-containing regimens, retinoids, azelaic acid, kojic acid, vitamin C or other pigment-modulating agents. Prolonged unsupervised hydroquinone use can cause irritation and rarely exogenous ochronosis.
Pigment-targeting devices
Selected lesions may be treated with wavelengths such as 532 nm, 755 nm or 1064 nm, or with broadband light/IPL. Device choice depends on pigment colour, depth, skin tone and diagnosis.
Chemical peels
Superficial peels can support epidermal turnover in selected pigmentation and acne-related PIH. Deeper or overly aggressive peeling can increase inflammation and PIH risk.
Melasma combination care
Topical therapy and photoprotection remain core treatments. Low-fluence laser or gentle resurfacing may be added selectively. Oral tranexamic acid is an off-label option in carefully screened patients and is not suitable for everyone because thrombotic risk must be considered.
Treat the cause of PIH
When pigmentation follows active acne or dermatitis, suppressing the inflammation often matters more than immediately targeting the brown mark. Otherwise new PIH can continue to form.

Melasma
Melasma is usually controlled, not permanently cured
Melasma can improve substantially, but recurrence is common because the underlying tendency remains. Pregnancy, hormonal medication, UV exposure, visible light, heat and genetic susceptibility can all influence recurrence.
Rapid melasma-removal promises are therefore misleading. A more realistic strategy is to reduce pigment, stabilise triggers, protect the skin barrier and maintain results with ongoing photoprotection and appropriate topical care.
Singapore specifics
Heat and visible light are underrated triggers here
Most pigmentation advice focuses on ultraviolet, but two other exposures matter considerably in this climate and are routinely overlooked.
Visible light
Ordinary daylight in the visible spectrum contributes to pigmentation in darker skin types, and conventional clear sunscreens filter it poorly. Tinted formulations containing iron oxides provide meaningfully better protection, which is why a tinted product is often recommended specifically for melasma rather than as a cosmetic preference.
Heat itself
Thermal exposure independent of ultraviolet can aggravate melasma. Cooking over a stove, hot yoga, saunas, prolonged commuting in the sun and even some facial treatments deliver enough heat to matter for susceptible patients.
Year-round exposure
There is no low-UV season here to allow recovery. Photoprotection is therefore a permanent habit rather than a seasonal one, and it is the intervention with the largest effect on whether results last.
Skin-tone safety
PIH risk matters in Asian and darker skin tones
Skin that tans or pigments easily may develop darker marks after inflammation. The goal is not simply to deliver enough energy to visibly disrupt pigment — it is to achieve improvement without creating an inflammatory response that leaves new pigmentation behind.
Conservative starting settings
Lower-energy settings or test spots may be appropriate when treating unfamiliar skin or pigment patterns.
Appropriate intervals
Allowing inflammation to settle before repeating treatment can reduce cumulative irritation.
Aftercare matters
Sun avoidance, barrier repair and doctor-directed skincare can materially affect whether pigmentation settles or rebounds.
What to expect
A diagnosis-first pigmentation consultation
History
Onset, hormones, sun exposure, acne or eczema, medicines and previous procedures.
Examination
Pattern, colour, border, depth clues, skin type and whether a lesion needs diagnosis first.
Plan
Topical care, photoprotection and procedural options are matched to the likely diagnosis.
Treatment
Settings and intervals are selected conservatively, especially when PIH risk is high.
Review
Response, recurrence and side effects are reviewed before escalating or changing treatment.
| Question worth asking | Why it matters |
|---|---|
| What do you think this pigmentation actually is? | If the answer is a device name rather than a diagnosis, that is worth noticing. |
| Could any of this fade on its own? | Much post-inflammatory pigmentation does, over months. Paying to treat it is optional. |
| What happens if treatment makes it worse? | A realistic plan anticipates rebound and has a response, rather than escalating energy. |
| How many sessions before we reassess rather than continue? | Open-ended packages remove the natural point at which a failing plan gets questioned. |
| What am I expected to do daily? | Photoprotection and topical adherence usually determine the result more than the device does. |
FAQ
Pigmentation treatment questions
Can pigmentation be permanently removed?
Some discrete sunspots or freckles may clear well, but new lesions can form with future sun exposure. Melasma and PIH are more prone to recurrence, so long-term control is more realistic than guaranteeing permanent removal.
Is laser always the best pigmentation treatment?
No. Laser can be useful for selected pigment types, but melasma and PIH may worsen if treatment is too aggressive. Diagnosis, skin tone and pigment depth should guide whether laser, light, topical therapy, peels or combination care is appropriate.
Can melasma get worse after laser?
Yes. Heat and inflammation can trigger rebound melasma or PIH in susceptible skin, which is why procedures are used cautiously and usually alongside photoprotection and topical treatment.
Can oral tranexamic acid be used for melasma?
It may be considered off-label in selected patients after medical screening. It is not appropriate for everyone, particularly where thrombotic risk or certain medical histories are present.
When should a brown spot be checked before laser?
A new or changing lesion, irregular border or colour, bleeding, ulceration, persistent itching, rapid growth or a lesion that simply looks different from your other spots should be medically assessed first.
How can I tell if my pigment is deep or superficial?
Superficial pigment tends to look brown and well defined, while deeper pigment often appears greyish, bluish or muddy with less distinct edges. It is a rough clue rather than a diagnosis, but a greyish cast suggests slower improvement.
My skincare has done nothing for my cheekbone pigmentation — why?
If it is speckled and blue-grey over the cheekbones, it may be Hori's naevus rather than melasma. Topical agents cannot reach dermal pigment, so the problem may be the diagnosis rather than the product.
Is Hori's naevus treatable?
Often yes, and it frequently responds well to appropriately selected pigment laser without melasma's rebound tendency. Accurate diagnosis can turn years of frustration into a treatable problem.
Can I have both melasma and Hori's naevus?
Yes, and that combination is one reason treatment that partly works then stalls deserves reassessment rather than more of the same.
Does heat really affect melasma?
Yes, independently of ultraviolet. Cooking over a stove, hot yoga, saunas and prolonged sun commuting can all aggravate it in susceptible patients.
Why is a tinted sunscreen recommended for melasma?
Visible light contributes to pigmentation in darker skin types and clear sunscreens filter it poorly. Tinted formulations containing iron oxides provide meaningfully better protection.
Does reapplying sunscreen actually matter?
Considerably. Sunscreen applied once in the morning is largely gone by afternoon, and for pigmentation-prone skin the reapplication habit matters more than the SPF number.
When would pigmentation appear after a treatment?
Post-inflammatory hyperpigmentation typically emerges two to six weeks afterwards rather than immediately, so skin that looks excellent at day ten can still darken.
Will my post-acne marks fade without treatment?
Flat brown or red marks commonly fade over months on their own. Sun protection accelerates it and picking prolongs it, so treatment is often optional rather than necessary.
Is hydroquinone safe to keep using?
It is effective but intended for supervised, time-limited courses. Prolonged unsupervised use can cause irritation and, rarely, exogenous ochronosis — a paradoxical darkening that is difficult to treat.
Can pigmentation treatment be done during pregnancy?
Several options are deferred, and melasma frequently arises or worsens in pregnancy. Photoprotection and pregnancy-appropriate topical care are usually the sensible approach until afterwards.
Why did my pigmentation come back after successful treatment?
The underlying tendency remains. Ultraviolet, visible light, heat and hormonal factors all drive recurrence, which is why maintenance is realistic and permanent cure claims are not.
How many sessions will I need?
There is no universal number, and an open-ended package removes the natural point at which a failing plan gets questioned. Agree in advance when you will reassess rather than simply continue.
Is pigmentation treatment claimable under MediSave or insurance in Singapore?
Cosmetic treatment is generally not claimable. Where a lesion requires medical diagnosis or removal, check directly with your insurer.
