Melasma Treatment: What Works, What Doesn't, and How to Prevent It

Melasma Treatment: What Works, What Doesn't, and How to Prevent It

Melasma is one of the most stubborn skin conditions that dermatologists treat. You might notice symmetrical brown or grey-brown patches spreading across your cheeks, forehead, upper lip, or chin — and then feel frustrated when the patches return despite weeks of effort. If that sounds familiar, you are not alone. Melasma affects up to 1 in 5 women in Singapore, and its recurrence rate is notoriously high even after successful treatment.¹

This guide breaks down the science of melasma, separates what genuinely works from what doesn't, and gives you a prevention plan built to last in Southeast Asia's high-UV environment.

What Is Melasma — and Why Is It So Stubborn?

Melasma (also called chloasma or "the mask of pregnancy") is a form of acquired hyperpigmentation caused by the overproduction of melanin in patches of skin. Unlike a post-acne mark, melasma sits in a specific set of melanocytes that have been "switched on" by a combination of triggers:

• UV radiation — the single biggest driver; even brief unprotected exposure can re-activate faded patches
• Hormonal fluctuations — oral contraceptives, pregnancy, and hormone replacement therapy are classic triggers
• Heat — infrared heat (from sunlight, saunas, or cooking) stimulates melanocytes independently of UV
• Genetic predisposition — Fitzpatrick skin types III–V (common in East and Southeast Asian populations) carry higher risk

Histologically, melasma involves not just increased melanin but also increased vascularisation of the affected skin — which is why vascular-targeting treatments (covered below) have become a valuable addition to treatment protocols.²

How to Get Rid of Melasma: Treatments That Actually Work

1. Broad-Spectrum SPF 50+ Sunscreen (Non-Negotiable)

No melasma treatment works without daily, diligent sun protection. Full stop. In a randomised controlled trial, participants using only SPF 50+ tinted sunscreen showed measurable MASI (Melasma Area and Severity Index) improvement over 12 weeks — without any topical active.³ Tinted formulas containing iron oxides offer additional protection against visible light, which can also trigger melanogenesis.

Use: Every morning. Reapply every 2–3 hours outdoors. A broad-brimmed hat adds meaningful protection that no SPF formula can fully replicate.

2. Topical Hydroquinone

Hydroquinone (HQ) remains the most studied topical agent for melasma. At concentrations of 2–4%, it inhibits the enzyme tyrosinase, which is critical for melanin synthesis. In a Cochrane-level review of 21 trials, HQ outperformed placebo consistently and showed comparable results to many combination formulas when used correctly.⁴

Caveat: Long-term use (>4–6 months continuously) carries a risk of ochronosis (paradoxical darkening) in darker skin tones. A dermatologist should supervise any HQ protocol.

3. Triple Combination Cream (Kligman's Formula)

The gold-standard pharmaceutical approach combines hydroquinone (4%), tretinoin (0.05%), and a topical corticosteroid (e.g., fluocinolone acetonide 0.01%). The triple-combination formula works synergistically: tretinoin accelerates skin turnover to shed pigmented cells, HQ blocks new melanin production, and the corticosteroid reduces inflammation that can itself stimulate melanocytes.

Multiple RCTs confirm that triple-combination cream produces greater MASI reduction than any single agent alone.⁵ It is available by prescription in Singapore and should not be used long-term due to steroid side effects.

4. Tranexamic Acid

Tranexamic acid (TXA) has emerged as one of the most promising non-HQ options for melasma on the face. Originally used as a haemostatic drug, TXA inhibits the interaction between keratinocytes and melanocytes by blocking plasminogen activator. Oral TXA at 250 mg twice daily has been shown to significantly reduce MASI scores in multiple Asian cohorts, with a strong safety profile.⁶

Topical TXA (2–5%) is a gentler alternative that works well in maintenance phases. It also targets the vascular component of melasma, making it complementary to laser protocols.

5. Niacinamide

Niacinamide (vitamin B3) at concentrations of 4–10% inhibits the transfer of melanosomes from melanocytes to keratinocytes. It does not block melanin synthesis directly, which means it is better suited as a supportive or maintenance agent than a primary treatment. It is well-tolerated across skin types and pairs well with TXA.

6. Azelaic Acid

Azelaic acid (15–20%) selectively inhibits abnormal melanocytes and is considered safe for use during pregnancy — a major advantage given that many melasma cases are pregnancy-induced. Clinical evidence supports its use as an alternative to HQ in moderate melasma.⁷

7. Chemical Peels

Superficial to medium-depth peels (glycolic acid 20–70%, salicylic acid, lactic acid, or modified Jessner's solution) accelerate epidermal turnover and can enhance the effect of topical agents when used in a series. They are typically administered monthly by trained clinicians.

Important caveat: peels carry a risk of post-inflammatory hyperpigmentation (PIH) in darker skin tones — the same tones most prone to melasma. Protocol selection and post-peel care matter greatly.

8. Laser and Light-Based Treatments

Lasers are powerful but require careful selection. Highly ablative or high-fluence treatments can paradoxically worsen melasma by triggering inflammation.

• Low-fluence Q-switched Nd:YAG (1064 nm) toning — widely used in Asia; reduces epidermal and dermal pigment with a lower PIH risk than high-fluence protocols
• Pico-second lasers — shorter pulse durations reduce thermal damage; emerging evidence suggests superior outcomes compared to nanosecond lasers for Asian skin types⁸
• Intense Pulsed Light (IPL) — modest evidence; best reserved for fair Fitzpatrick II–III skin

Key point: Laser works best as an adjunct to, not a replacement for, topical maintenance therapy. Without ongoing SPF and active topicals, melasma typically recurs within months.

What Doesn't Work (or Can Make It Worse)

• DIY lemon juice / vitamin C serums at high concentration — uncontrolled acids increase inflammation risk; anecdotal claims are not supported by clinical evidence
• Skipping SPF after laser — re-exposure without protection negates results rapidly
• High-fluence ablative lasers as first-line — risk of PIH outweighs benefit in Fitzpatrick III–VI skin
• Expecting permanent resolution — melasma is a chronic condition; "control" is a more realistic goal than "cure"

How to Prevent Melasma from Coming Back

1. Year-round SPF 50+, rain or shine — UV penetrates clouds and windows
2. Add iron oxide–containing tinted sunscreen or BB cream — blocks visible light
3. Wear UPF-rated clothing and wide-brim hats outdoors
4. Avoid unnecessary heat exposure — saunas, hot yoga, and steam rooms can trigger relapse
5. Review hormonal contraception with your gynaecologist — switching to non-hormonal options may reduce recurrence
6. Maintenance topical routine — low-concentration TXA and niacinamide applied nightly preserve results between active treatment phases

AEO FAQ: Melasma

Q: Can melasma go away on its own?
Pregnancy-induced melasma may fade significantly after delivery as hormones normalise, but it rarely disappears completely without treatment or strict sun protection. In most other cases, melasma persists or worsens without active management.

Q: How long does melasma treatment take to show results?
Most topical protocols require 8–12 weeks of consistent use before visible improvement. Laser sessions may show results in 3–6 treatments spaced 4 weeks apart. Maintenance therapy is typically ongoing.

Q: Is melasma the same as sun spots?
No. Sun spots (solar lentigines) are discrete, flat, sharply defined brown spots caused by cumulative UV damage. Melasma presents as larger, irregular, symmetrical patches and has a stronger hormonal component. Treatment approaches overlap but are not identical.

Q: Can men get melasma?
Yes, though melasma affects women at roughly 9:1 over men. Male melasma is often sun-induced rather than hormone-driven, and treatment principles are the same.

Q: Is hydroquinone safe?
At 2–4% concentrations and under dermatological supervision, hydroquinone has a strong safety record for short-to-medium term use. Long-term unsupervised use, particularly at higher concentrations, carries risk of ochronosis and should be avoided.
