Melasma Treatment: Why It's Different From Regular Pigmentation
Melasma is a hormonally driven pigmentation pattern that keeps coming back unless you manage its triggers, not just the visible colour.
Quick answer: Melasma forms because hormones and sun exposure keep melanin production continuously elevated in a way ordinary dark spots do not. Unlike a post-acne mark that fades as skin heals, melasma returns whenever a trigger is present, so treatment has to reduce visible colour and stop new colour forming at the same time. Daily sunscreen is non-negotiable; a topical routine with kojic acid and niacinamide then does useful work on top. See a dermatologist if patches have not shifted after three months of consistent care, are spreading, or appeared suddenly without an obvious trigger.
If you have spent months using a vitamin C serum on a brown patch across your cheeks and seen almost nothing change, there is a good chance you are dealing with melasma rather than ordinary hyperpigmentation. The two look similar but behave very differently, and treating them the same way usually explains why results disappoint.
What makes melasma different
Most dark spots on Indian skin come from inflammation. An acne lesion heals and leaves a flat brown mark behind; the skin produced extra colour as part of the wound response, and it fades as the skin turns over. This is post-inflammatory hyperpigmentation, and it responds reasonably well to brightening ingredients given enough time.
Melasma works differently. The pigment-producing cells are not reacting to an old injury. They are kept in a continuously active state by hormones, UV exposure, and in some cases heat. The cells produce melanin steadily rather than as a one-off response, which is why melasma patches are larger, more symmetrical, and sit across the cheeks, forehead, and upper lip rather than at the site of an old spot. A post-acne mark left alone fades within six to eighteen months. Melasma patches managed with no sun protection and no topical routine can stay for years, deepening whenever a trigger returns.1
What triggers it and what keeps it going
Understanding the triggers matters before you pick a product, because the wrong treatment can make melasma worse rather than better.
- Sun and daylight exposure. Even a short time outdoors without sunscreen can deepen melasma within a day or two. UV is not the only light that matters; visible light also stimulates the pigment pathway in darker skin tones, which is one reason melasma on Indian skin is harder to clear than studies on lighter-skinned populations suggest.
- Hormonal changes. Pregnancy is the best-known trigger, which is why melasma is sometimes called the mask of pregnancy. Oral contraceptives and hormone replacement therapy can have the same effect. The hormonal component should be discussed with your doctor rather than managed through skincare alone.
- Heat. Some people notice melasma darkens after a hot shower, exercise, or a long commute. Heat can stimulate pigment production independently of UV, which is why melasma tends to be worse in summer in India even when someone is reasonably careful about direct sun.
- Irritation. Aggressive scrubs, strong chemical peels, or laser treatments used without proper assessment can cause a post-inflammatory flare on top of existing melasma. A routine that regularly irritates the skin tends to prolong pigmentation rather than clear it.
How topical ingredients work on melasma
Kojic acid slows the enzyme that produces melanin, working on pigment at the source rather than on colour already formed. Niacinamide works later in the same process by reducing the transfer of melanin from the cells that make it to the skin cells at the surface. Using them together addresses the pathway from two directions.1 Niacinamide also strengthens the skin barrier and reduces surface inflammation, which matters because a disrupted barrier keeps skin reactive and makes it harder to tolerate actives without flaring.
A 2023 systematic review in the Indian Dermatology Online Journal covering topical and systemic therapies for melasma, with a focus on darker skin populations, found that combination approaches targeting more than one step of the pigment pathway consistently outperformed single-ingredient treatments, and that photoprotection is core to any melasma plan, not optional.2

Choose by skin concern
For uneven tone and lingering pigment, a serum that combines kojic acid, niacinamide, and barrier support in one step keeps the routine simple and lowers the risk of irritation.
Building a routine that does not make things worse
The most important addition to a melasma routine is sunscreen, worn every morning, reapplied if you are outdoors. No topical brightener can outpace daily UV resetting the pigment pathway. Once that is covered, an active serum can start doing useful work.
A melasma routine works best when it is short. More actives mean more chances for irritation, and irritation deepens pigment. The routine that tends to work is one active serum on clean, damp skin, a moisturiser, and sunscreen each morning. The Dark Spots, Pore Control Serum combines kojic acid and niacinamide with five ceramides and Centella asiatica in a single step. Directions: cleanse, apply 3 to 4 drops on damp skin, moisturise, and use sunscreen in the morning. It is designed as the only active step, so extra retinol or brightening acids are not needed alongside it. In the serum's own clinical study, 100% of patients improved dark spots in 8 weeks with twice-daily use in 36 Indian women aged 24 to 44; results may vary.
Keep in mind
Melasma responds slowly, and visible improvement usually takes at least eight to twelve weeks of consistent use. If patches are spreading, become raised, or appeared very suddenly, see a dermatologist before starting any active ingredients.
Melasma versus post-inflammatory hyperpigmentation at a glance
| Melasma | Post-inflammatory hyperpigmentation | |
|---|---|---|
| Cause | Hormones, UV exposure, heat, genetics | Inflammation from acne, eczema, or a wound |
| Pattern | Symmetrical patches on cheeks, forehead, upper lip | Flat marks at the site of healed breakouts or injury |
| Without treatment | Persists; deepens with sun or hormonal change | Gradually fades as skin turns over (6 to 18 months) |
| Treatment priority | Trigger control first, then topical brightening | Topical brightening; anti-inflammatory care for active breakouts |
Timelines and maintenance
Melasma improvement is measured in months. The first change you are likely to notice is that patches stop deepening and the edges look less sharp. Visible lightening usually comes between eight and sixteen weeks of consistent topical use and good sun protection; deep pigment takes longer, and topical treatment alone may not be enough. Finishing a course of treatment does not reset the skin permanently. Warm months, a contraceptive change, or a run of skipped sunscreen can bring patches back. A 2019 systematic review of randomised controlled trials on topical melasma treatments found that recurrence is common and that photoprotection is central to maintaining any improvement.3
When to see a dermatologist
Melasma responds to topical management for many people, but some situations call for a dermatologist rather than another serum:
- No change after three months. If patches look exactly the same after three months of consistent sunscreen and topical care, it is worth checking whether the diagnosis is correct and whether deeper or hormonal melasma needs a different approach.
- Spreading or new patches. Melasma spreading despite sun protection may need a systemic option such as oral tranexamic acid, which a dermatologist can assess and prescribe.
- Sudden or unusual onset. A pigmentation pattern that appeared very quickly, is raised or itchy, or sits outside the typical cheek and forehead distribution should be assessed before treating at home.
- Hormonal treatment involved. If melasma appeared or worsened after a change in contraceptive or during or after pregnancy, a doctor should be part of the conversation.
Frequently asked questions
Can melasma go away on its own?
It can fade when triggers are absent, such as after pregnancy ends or when hormonal contraceptives are changed, but it rarely clears completely without consistent sun protection and topical treatment. For most people it is a long-term condition to manage rather than a short-term one to cure.
Is melasma the same as sun damage?
No, though sun exposure worsens both. Sun damage produces scattered spots from cumulative UV over years. Melasma produces larger, more uniform patches driven by hormonal sensitivity and UV together, and it typically appears symmetrically on both sides of the face.
Does vitamin C clear melasma?
Vitamin C supports a more even-looking tone by reducing oxidative stress at the surface, and it is a useful part of a broader routine. On its own it is not strong enough to clear established melasma, particularly deeper patches. It works better alongside ingredients that slow melanin production at the source, such as kojic acid.
Why does melasma come back after treatment?
Topical treatment reduces visible pigment but does not permanently change the skin's sensitivity to its triggers. Sun exposure, hormonal shifts, or heat can reactivate the pathway. Staying on a maintenance routine with consistent sunscreen is what keeps improvement from being temporary.
Can I use a brightening serum while pregnant?
Pregnancy itself can cause melasma, but ingredient choices during pregnancy should be discussed with your doctor first. Check with your doctor if you are pregnant or breastfeeding before adding any new active serum.
Will a laser treatment clear melasma?
Laser and light-based treatments have mixed results for melasma. Some approaches that work well for post-inflammatory hyperpigmentation can cause a pigment flare in melasma-prone skin. A dermatologist should assess the type and depth of pigment before any procedural treatment.
How long does topical treatment take to work?
Most people notice that patches stop deepening within four to six weeks. Visible lightening usually takes eight to sixteen weeks or longer, depending on how deep the pigment is and how consistently sunscreen is used alongside the serum.
Is melasma more common in India?
It is more commonly reported in India and other South Asian countries. Darker skin tones are more prone to visible pigmentation changes from hormonal shifts or sun exposure, and the climate means higher average UV exposure year-round. The condition affects all skin types but tends to be more persistent in people with darker complexions.
