the short answer. Melasma is a chronic, hormone-driven pigmentation condition that affects 15 to 35% of Bangladeshi women of reproductive age. The at-home protocol that works is a 12-week build: azelaic acid 10% nightly, niacinamide 10% in the morning, and a brightening SPF50+ PA++++ reapplied every 90 minutes when outdoors. Expect visible softening at week 8, meaningful fade by month 4, and a quiet acceptance that this needs maintenance forever. If you are pregnant or breastfeeding, the same protocol works minus the retinol additions in week 9. Total foundation: under BDT 4,000.

why melasma is so common in bangladesh

Melasma needs three things to develop, and Bangladesh hands its women all three at once.

First, genetic susceptibility. Fitzpatrick III to V skin tones (the typical Bangladeshi range) carry more active melanocytes that respond more aggressively to triggers. Second, hormonal exposure. Pregnancy, oral contraceptives, hormonal cycles, and even chronic stress all sensitise those melanocytes. And third, UV pressure. Dhaka spends nine months of the year in the WHO's "extreme" UV category. The combination is what turns a few sensitised melanocytes into the symmetrical brown patches on your cheeks that you have probably been trying to cover with foundation.

Roughly 15 to 35% of Bangladeshi women of reproductive age have active melasma at any given time. (source) If you are dealing with it, you are not unlucky. You are part of a quiet majority of women in your peer group who probably also have it and have not talked about it.

is it actually melasma? (and not pih or sun spots)

Treating melasma with PIH products gets you nowhere. The first job is to confirm what you are looking at.

Melasma looks like: Larger, symmetrical patches of brown or grey-brown discolouration. Edges are soft, not sharp. The shape often looks like a map or lace. Almost always on both sides of the face in roughly mirror-image patterns.

Where it shows up: Cheekbones, upper lip (the "moustache shadow"), forehead, sometimes the jawline. The pattern is symmetrical.

How it differs from PIH: PIH appears as discrete spots that match the shape of an old breakout or scratch. Melasma is patches. PIH is often asymmetric. Melasma is almost always symmetric.

How it differs from sun spots: Sun spots are small (a few millimetres), sharply defined, often round, and they appear in the highest-sun areas (cheekbones, temples). Melasma is larger patches with soft edges.

If you cannot tell, do not guess. The free 10-minute dermatology consultation at most Dhanmondi or Gulshan clinics will confirm with a Wood's lamp examination and is genuinely worth your time. The wrong treatment can make melasma worse, especially if it involves aggressive exfoliation or laser on dermal-type melasma.

the three melasma types (and why your treatment response depends on it)

Dermatologists classify melasma by how deep the pigment sits in the skin. The depth predicts how well topicals will work. (source)

Epidermal melasma: Pigment in the upper skin layers. Dark brown, well-defined edges. Brightens under a Wood's lamp. Best response to topical treatment. Most readers in their 20s and early 30s have this type. Expect meaningful fade with the 12-week routine below.
Dermal melasma: Pigment in the deeper dermis. Light brown or bluish-grey. Blurry edges. Does not brighten under Wood's lamp. Poor response to at-home topicals. Often needs professional treatment (laser, chemical peels) for meaningful improvement. Topicals still help with maintenance.
Mixed melasma: Both types together. Both bluish and brown patches. The most common pattern. Partial response to topicals — surface improves, deeper pigment is more stubborn.

The honest takeaway: if you have epidermal or mixed melasma, the 12-week routine below is your starting point. If you have dermal melasma, do the routine and book a derm consult — at-home alone may plateau before you see substantial change.

what actually triggered yours

Identifying the trigger does not fix the melasma, but it explains the timing and helps you predict what to watch for.

Pregnancy. Chloasma — the medical name for pregnancy melasma — affects 50 to 75% of Bangladeshi women during pregnancy. Often visible from the second trimester. Triggered by oestrogen and progesterone rises.
Oral contraceptives. Combined hormonal contraceptives can trigger melasma months after starting them. If yours started after you began the pill, this is likely the cause.
Hormonal cycles. Some women notice melasma worsens premenstrually each month. This is real, not in your head, and it usually means the underlying sensitivity is hormonal.
Stress. Cortisol affects melanocyte sensitivity. Chronic stress (work, exam season, postpartum sleep deprivation) makes existing melasma harder to fade.
Heat alone. Heat without sun can trigger melasma in susceptible skin. This is why melasma sometimes appears or worsens on the side of the face exposed to a window or a hot kitchen, even with sunscreen on.

Sun is the constant amplifier on all of these. Even if hormones triggered the initial pigment, ongoing UV exposure is what makes it darken and persist.

the 12-week at-home routine that actually works

This is a build, not a sprint. Each phase is four weeks. Do not skip ahead — adding too much too fast is the single biggest reason melasma routines fail.

phase 1: weeks 1–4 — foundation

Build the habit and let your skin adapt before introducing any second active.

Morning: Cleanser → niacinamide 10% → moisturiser → Celimax Pore + Dark Spot SPF50+ PA++++. Reapply SPF at lunch and at 3pm without exception.
Evening: Cleanser → Anua Azelaic Acid 10% → moisturiser. Three nights a week for the first two weeks, then every night by week four.
Watch for: Mild stinging on the first few applications of azelaic acid is normal. Persistent redness or burning is not — stop and patch test on the jawline.

phase 2: weeks 5–8 — add vitamin c

Vitamin C boosts the antioxidant defence against new UV-driven pigment and modestly fades existing patches. Safe in pregnancy.

Morning add: Arencia Vitamin C Booster Shot (BDT 1,750) after cleansing, before niacinamide. Wait 60 seconds between layers.
Evening: Same azelaic acid routine. By now your skin should tolerate nightly application without stinging.
Expected: First visible softening of patch edges around week 6. Take a photo every two weeks under the same lighting — your eyes adapt to your face.

phase 3: weeks 9–12 — intensify (non-pregnant only)

This is where the deeper work starts. If you are pregnant or breastfeeding, skip this phase entirely and stay on phases 1 and 2. The pregnancy-safe stack works; it just plateaus a few percentage points lower.

Evening add: Celimax Vita-A Retinol Shot Serum (BDT 1,699) twice a week to start. Alternate with azelaic — never the same night. Retinol speeds up cell turnover and helps push out pigmented cells.
Optional weekly: The Ordinary Glycolic Acid 7% Toner (BDT 1,890) once a week, only on non-treatment nights. Surface exfoliation accelerates fade by removing the most superficial pigmented cells.
Stop conditions: If your skin gets red, peeling, or stings continuously, scale back to phase 2. More is not better with melasma — inflammation triggers more pigment.

phase 4: maintenance (forever)

Melasma is chronic. Once you have faded it, you will need to maintain it. This is not a flaw in your routine — it is the biology of the condition.

Daily: Niacinamide AM, brightening SPF AM with reapplication, gentle moisturiser PM.
3 nights a week: Azelaic acid as maintenance.
1 night a week: Retinol (if not pregnant). Glycolic acid optional weekly.
Watch for triggers: Pregnancy, new contraceptive pill, summer humidity peaks. Increase frequency back to the phase 3 protocol the moment patches start returning.

the pregnancy-safe variant (read this if you are pregnant or breastfeeding)

If you are pregnant or breastfeeding, the pregnancy-safe protocol is: azelaic acid 10% nightly, niacinamide 10% in the morning, vitamin C in the morning, and a brightening SPF50+ PA++++. That is it. Skip retinol entirely. Skip kojic acid. Skip hydroquinone. Skip tranexamic acid. Glycolic acid is borderline — most dermatologists allow up to 10% but check with yours first.

Why this is enough: azelaic acid is FDA Category B, has minimal systemic absorption, and a single clinical trial showed 20% azelaic acid cream twice daily reduced the Melasma Area and Severity Index by 50% at 8 weeks. (source) Niacinamide is well-tolerated in pregnancy and blocks pigment transfer. Vitamin C is safe and supports antioxidant defence. The combination is not as fast as a full retinol-augmented protocol, but it is meaningfully effective and it is safe.

Postpartum timeline: Studies show 50 to 70% of women see their melasma improve naturally within the first year after delivery, especially with diligent sunscreen. (source) About 30% of patches persist longer. If you are still nursing, the prolactin elevation can keep melasma sensitive for longer — vitamin C, azelaic acid, and glycolic acid remain safe options during breastfeeding. (source) Once breastfeeding ends, you can add retinol back in.

sunscreen is doing 70% of the work

If you take one thing from this guide, take this: the best topicals in the world will not fade melasma if you skip or under-apply sunscreen. Every UV photon reactivates the pigment-producing pathway you are trying to calm.

For melasma specifically, you want:

SPF50+ PA++++ with broad-spectrum protection.
Iron oxides if possible. Iron oxides give partial protection against high-energy visible blue light, which is implicated in melasma worsening (think: office lighting, phone screens, sun). Tinted sunscreens often contain them.
Reapplication every 90 minutes when outdoors, every 3 hours indoors near windows. This is the part most BD women skip and the reason most melasma plateaus.

Our specific picks for melasma:

Celimax Pore + Dark Spot Brightening SPF50+ PA++++ (BDT 1,560). Sunscreen with brightening complex. Our top single-pick for melasma.
Beauty of Joseon Relief Sun (BDT 1,560). All-rounder, dewy but no white cast.
Christian Dean Secret Tone-Up SPF50+ (BDT 480). The tone-up tint contains pigments similar to iron oxides — gives partial blue light coverage. Budget pick.
SKIN1004 Madagascar Centella Sun Serum (BDT 1,400). If you also have oily skin or breakouts.

Our complete BD sunscreen guide covers the wider picture and the science of why PA++++ matters more than SPF50 for melasma.

when at-home plateaus and you should see a dermatologist

Most epidermal and mixed melasma responds well to the 12-week routine. But not all of it. See a dermatologist if:

You have completed 12 weeks of consistent treatment and seen zero visible change.
Your melasma looks bluish or grey-brown (probably dermal type — needs professional treatment).
Patches are spreading despite treatment.
You want to consider oral tranexamic acid, microneedling, or laser. These have stronger evidence for stubborn melasma and need medical supervision.

A dermatologist consultation in Dhanmondi or Gulshan typically runs BDT 800–2,000. For melasma specifically, look for derms who have specific experience with melanin-rich skin — the wrong laser settings on Fitzpatrick IV–V skin can paradoxically worsen pigmentation.

the four most common bangladesh melasma mistakes

1. "Fairness creams" from pharmacies and Facebook pages. Many products marketed as melasma treatments in BD contain undeclared hydroquinone at high concentrations, mercury, or topical steroids. They appear to work for the first few weeks. Then they cause steroid-induced rosacea, paradoxical darkening, or worse. If you cannot read the full ingredient list in plain English, do not put it on your face.

2. Aggressive exfoliation. Physical scrubs, harsh peels, daily AHA toners. All make melasma worse because they trigger inflammation, and inflammation triggers more pigment. Gentle is the entire game. Slow gentle progress beats fast aggressive temporary results that come with rebound.

3. Inconsistent sunscreen. Most BD melasma stories have the same arc: routine works for 2 months, gets distracted in summer travel or Eid prep, skips SPF for two weeks, patches are back darker than before. Sunscreen is non-negotiable, every day, reapplied multiple times. There is no shortcut.

4. Quitting at week 6 because "it stopped working." Weeks 4 to 8 are the plateau period in every long-term skincare protocol. People look in the mirror, decide the routine is not working, abandon it, and miss the compound results that appear at week 12 and beyond. Trust the timeline. Take photos.

frequently asked questions

what is the best melasma cream available in bangladesh?

The strongest at-home pick stocked in BD is Anua Azelaic Acid 10% (BDT 999). Azelaic acid has FDA Category B safety, works for all three melasma types (best on epidermal), and is the only treatment we recommend that is safe through pregnancy and breastfeeding. Pair it with niacinamide and a brightening SPF for the full effect.

how long does melasma take to fade?

Honest timeline: subtle softening around week 4, visible fade on patch edges by week 8, meaningful improvement by months 4 to 6. Melasma is the slowest of the hyperpigmentation conditions because it sits deeper and is hormone-driven. Anyone promising fade in two weeks is either selling a temporary brightening effect or a product with illegal bleaching agents.

is melasma permanent?

Melasma is chronic, not permanent. It can be substantially faded with consistent treatment, but it tends to return when triggers re-appear (new pregnancy, hormonal changes, intense sun exposure, stress). Treat it like an ongoing maintenance condition rather than a one-time fix.

can i use retinol for melasma during pregnancy?

No. Topical retinoids including retinol, retinaldehyde, tretinoin, and adapalene should be avoided during pregnancy and breastfeeding. Stick to the pregnancy-safe stack: azelaic acid, niacinamide, vitamin C, and a strong SPF. You can add retinol back after weaning.

does melasma go away after pregnancy?

Approximately 50 to 70% of women see their pregnancy melasma improve naturally within the first year postpartum, especially with diligent sunscreen. About 30% of patches persist longer. Breastfeeding can prolong the hormonal sensitivity. The pregnancy-safe routine in this guide remains safe during breastfeeding and helps fade what persists.

what triggers melasma flare-ups in bangladesh?

The most common triggers our customers report: peak summer UV (May–August), pregnancy, starting hormonal contraceptives, premenstrual hormonal shifts, prolonged sun exposure on travel, chronic stress, and forgetting sunscreen for two weeks straight. Track your flares and you will usually find a pattern.

is laser treatment worth it for melasma in bangladesh?

It depends on type. Epidermal melasma can respond to certain Q-switched lasers and pulsed-dye lasers in experienced hands. Dermal and mixed melasma is harder, and the wrong laser on Fitzpatrick IV–V skin can trigger post-inflammatory hyperpigmentation that is worse than the original melasma. If you consider laser, find a dermatologist with specific experience in melanin-rich skin and ask how many similar cases they have done.

can men get melasma in bangladesh?

Yes, though much less commonly. About 10% of melasma cases are male. Triggers are typically chronic UV exposure (outdoor work) and occasionally hormonal medications. The same at-home routine works.

what about kitchen-ingredient remedies — lemon, turmeric, milk?

Skip them. Lemon juice on skin triggers a phototoxic reaction that makes melasma worse, not better. Turmeric stains skin and irritates many people. Milk and besan masks are gentle but not meaningfully effective for melasma. Spend the money on niacinamide and azelaic acid instead — both are evidence-backed and not expensive.

one more thing

Most of what we hear from women dealing with melasma is a quiet version of the same thing: it makes them feel older than they are, it does not respond to makeup the way they want it to, and they have tried five things that did not work. We understand. The honest answer is that no single product is going to undo melasma in a month, but the right four products done consistently for twelve weeks will give you back a visible chunk of your skin. After that, maintenance is real but manageable.

If you want a place to start, the foundation stack is azelaic acid 10%, niacinamide 10%, a brightening SPF, and a vitamin C if budget allows. Under BDT 5,500 total. Run it for twelve weeks. Photograph every two weeks. Most of you will see change.
