Why melasma is different from other pigmentation
Most pigmentation in Singapore is sun-induced — sunspots, freckles, post-inflammatory hyperpigmentation from old acne. These respond well to standard treatments: a single picosecond laser session can lighten a sunspot dramatically.
Melasma is the exception. It's hormonally driven, typically symmetric across the cheekbones, forehead, and upper lip, and it has a deeper component that involves the melanocytes themselves — not just the pigment they deposit. Treating it the same way you'd treat a sunspot doesn't work, and can actively make it worse.
What causes melasma
Several factors contribute:
- Hormonal influence — melasma is much more common in women, and often emerges or worsens during pregnancy, with oral contraceptives, or with hormone replacement therapy.
- UV exposure — not just direct sunlight, but also visible light. Even short, casual sun exposure can trigger flare-ups.
- Heat — ambient heat (cooking, hot environments) can worsen melasma independent of UV.
- Genetic susceptibility — some people are simply more predisposed than others, particularly Fitzpatrick skin types III to V common in Singapore.
- Inflammation — aggressive aesthetic treatment, allergic reactions, or skincare irritation can all trigger melasma flares.
Why melasma is so common in Singapore
Three reasons converge:
- Equatorial sun: Singapore sits at 1.3° latitude. UV index is high year-round, with little seasonal variation. Patients accumulate UV dose continuously.
- Skin type: most Singaporean patients are Fitzpatrick III to V — these skin types have more responsive melanocytes that produce more pigment in response to any trigger.
- Heat and humidity: the daily ambient temperature itself can act as a melasma trigger independent of sun exposure.
The combination makes melasma management harder here than in most temperate climates.
How doctors typically approach melasma
1. Diagnosis first
Not all pigmentation is melasma. Your doctor will examine the pattern (symmetric? cheekbone-dominant? sharp or diffuse edges?), use a Wood's lamp or dermatoscope if needed, and rule out conditions that look like melasma but require different treatment: post-inflammatory hyperpigmentation, lichen planus pigmentosus, naevus of Ota, or simple sun damage.
2. Sun protection — non-negotiable
Before any in-clinic treatment, you'll be set up with a daily SPF regimen. Without consistent sun protection, no melasma treatment works. We typically recommend a broad-spectrum SPF 50+ that also protects against visible light — mineral-based formulations with iron oxides are particularly helpful for this.
3. Topical and oral therapy
Most melasma treatment plans include a prescription topical regimen — commonly a combination of hydroquinone, tretinoin, and a mild corticosteroid (the "Kligman formula") used cyclically. Some patients also benefit from oral tranexamic acid prescribed by a doctor. These are reviewed regularly.
4. In-clinic procedures — the gentle approach
This is where melasma is most different from other pigmentation. Aggressive lasers don't help and often hurt. Modern protocols typically use:
- Picosecond laser at low fluences — gentle settings that lighten surface pigment without provoking melanocytes.
- Selective RF microneedling (pulsed wave mode) — specifically designed to target the abnormal vasculature that feeds melasma without thermally activating melanocytes.
- Thulium 1927nm fractional laser — gentler than ablative resurfacing, used for surface tone correction.
Treatment is incremental — small sessions, longer spacing, careful observation between sessions. Patience is part of the protocol.
What to avoid
If you have melasma, these are the warning signs that you're at the wrong clinic:
- Promises of "permanent" results. Melasma is chronic. Any clinic promising permanent clearance is overpromising.
- Aggressive single-session protocols. Q-switched laser at high fluences. Aggressive chemical peels. Anything that promises dramatic results in one visit.
- No prescription regimen. Melasma treatment without a topical and lifestyle programme is incomplete care — in-clinic procedures alone don't work.
- Generic protocols. Your protocol should reflect your Wood's lamp pattern and skin type, not a clinic template.
Realistic expectations
Here's the honest framing we set with melasma patients at first consultation:
- Improvement, not cure. We aim to fade existing pigmentation by 50 to 70% and reduce recurrence frequency.
- 3 to 6 months minimum. Visible improvement typically takes 3 to 6 sessions over 3 to 6 months. There are no overnight wins with melasma.
- Lifelong maintenance. Sun protection forever. Periodic in-clinic top-ups. The underlying susceptibility doesn't disappear.
- Flares happen. Pregnancy, contraception changes, holiday sun, or a bad week of stress can all bring melasma back. We manage flares as they occur.
The bottom line
Melasma management is more about steady patient discipline plus careful clinical guidance than any single dramatic treatment. The best outcomes come from clinics that explain this honestly up front and structure long-term care — not from clinics that promise quick fixes.
If you're concerned about pigmentation that's been resistant to previous treatment, or if you've been told elsewhere that "lasers will fix it" but it kept coming back, a structured assessment may be useful. Our doctors will classify your pigmentation pattern, set realistic expectations, and discuss what an actual treatment plan would involve.
