Melasma is a chronic pigment disorder: symmetric brown or gray-brown patches, usually across the cheeks, forehead, upper lip, and bridge of the nose. It is driven by ultraviolet light, visible light, heat, and hormones, and it is far more common in people with medium to dark skin. In one global study of 324 patients, 48% had a blood relative with melasma, so genetics load the gun and sun and hormones pull the trigger. The patches fade and flare for years. Treatment can lighten them and hold them down, but nothing makes melasma go away for good.
Melasma is not the same as dark spots
These two get confused constantly, and treating one like the other wastes months. Dark spots are post-inflammatory hyperpigmentation: the flat marks acne, eczema, razor bumps, or any injury leaves behind. They sit exactly where the skin was inflamed, they are usually scattered and asymmetric, and once you treat the trigger they tend to fade. We cover that in detail in our guide to dark spots and hyperpigmentation on Black skin.
Melasma is its own disorder. The patches are symmetric, mirrored on both cheeks or across the forehead, and not tied to a pimple or a scratch. The drivers are external (sun, visible light, heat) and internal (estrogen and progesterone). The pigment often sits deeper in the skin, and that depth is why melasma resists the creams that work on surface dark spots. A dermatologist may use a Wood lamp to gauge how deep the pigment runs: epidermal melasma sits near the surface and lights up under the lamp, dermal melasma sits deeper and does not, and mixed melasma has both. Deeper pigment is slower to respond.
What triggers and worsens it
Sunlight, including visible light. UV is the single biggest external driver, but visible light matters just as much on darker skin, and that changes the rules. Visible light is the part of sunlight you can see, and it also comes off screens and through window glass. Ordinary chemical SPF blocks UV but does little against visible light. This is why a sunscreen that controls melasma in a fair-skinned person can leave a Black patient flaring. In a randomized trial, melasma patients who used a sunscreen with both UV and visible-light protection had far fewer relapses over six months than those using a UV-only sunscreen.
Hormones. Estrogen and progesterone stimulate the pigment cells. That is why melasma is often called the mask of pregnancy, and why it can flare on combined birth control pills, the patch, or hormone therapy. If your melasma started with a pregnancy or a new contraceptive, that is the cause, and it is worth a conversation with your clinician about non-hormonal or lower-estrogen options.
Heat. Heat alone, separate from light, can drive melasma. Cooking over a stove, saunas, hot yoga, and working outdoors in summer all count. You do not have to be in direct sun to flare.
Screens and windows. Because visible light drives melasma on darker skin, exposure is not limited to going outside. Glass blocks most UVB but lets visible light and UVA through, and device screens emit visible light too. That is why daily sunscreen matters even on indoor days near a window.
Why it hits Black skin harder, and why it is not just cosmetic
Melasma is most common in people with Fitzpatrick skin types III and IV, the medium-brown to dark-brown range, because more active pigment cells mean a stronger response to the same sun, heat, and hormonal signals. The same biology makes it slower to clear and quicker to come back. Prevalence runs around 1% in the general population and as high as 9% to 50% in higher-risk groups, tracking skin tone, ancestry, and sun exposure.
It is not just a cosmetic nuisance. Researchers built a dedicated quality-of-life scale, the MELASQOL, specifically because melasma affects appearance, social life, and emotional well-being more than it affects people physically. Dismissing it as vanity misses what patients actually experience.
Why aggressive treatment and lasers can backfire
The instinct is to hit melasma hard. On Black and brown skin, that instinct is dangerous. Any inflammation can wake up the pigment cells and make the patches darker, so a treatment strong enough to irritate the skin produces the opposite of what you wanted.
Lasers are the clearest example. In darker skin, Q-switched and other energy-based lasers used too aggressively, or as a standalone fix, frequently cause post-inflammatory hyperpigmentation on the treated skin and rebound darkening after treatment stops. Reviews of laser therapy in melasma report high recurrence and a real risk of new pigmentation in Fitzpatrick types IV and V. Strong chemical peels carry the same risk. Procedures are not off the table, but they are a later step, low energy, and only with a clinician who treats skin of color regularly.
The evidence-based treatment ladder
1. Tinted, iron-oxide broad-spectrum sunscreen. First and non-negotiable. No melasma treatment works without it, and on darker skin it has to be tinted, because the iron oxides that give tinted sunscreen its color are what block visible light. Use a broad-spectrum SPF 30 or higher with iron oxides (look for tinted on the label and iron oxides in the ingredients), every day, reapplied, indoors near windows and screens too. This is the one step that protects every other treatment from being undone.
2. Topicals. Several have real evidence:
- The triple-combination cream (hydroquinone 4%, tretinoin 0.05%, fluocinolone acetonide 0.01%) is the best-studied prescription option and the standard first-line topical, shown effective and reasonably safe over up to 12 months under a dermatologist's supervision.
- Hydroquinone on its own works, but it is used carefully and time-limited. Long-term unsupervised use, especially at high strength, can cause exogenous ochronosis, a blue-black discoloration that mostly affects people of African descent and is hard to reverse. Treat it as a clinician-guided short course, never an imported jar you use forever.
- Azelaic acid, cysteamine, and kojic acid are non-hydroquinone options. Cysteamine 5% cream performed comparably to a hydroquinone combination cream in head-to-head trials and is suitable for longer-term use because it is not toxic to pigment cells.
- Retinoids (tretinoin) help by speeding cell turnover, but start low and slow, because the irritation they cause can itself trigger more pigment on darker skin.
3. Oral tranexamic acid. For stubborn or widespread melasma, low-dose oral tranexamic acid added to topicals and sun protection has strong trial support. A meta-analysis of randomized trials found significant reductions in melasma severity scores at 8 and 12 weeks. It is prescription-only and carries a small clotting risk, so it is off the table for people with a history of blood clots. That screening is why it is a clinician's call, not a supplement you buy online.
4. Cautious, low-energy procedures. Superficial chemical peels and low-fluence lasers can help when topicals and oral options stall, but only at low intensity, paired with topicals and strict sun protection, and only with a clinician experienced in darker skin. Done wrong, they set you back.
How to get care
Melasma on Black skin is treatable, but the margin for error is small, and the wrong laser or too-strong a cream can leave you worse than you started. The single most important factor is a clinician who treats skin of color routinely and knows to lead with visible-light protection and gentle topicals before anything aggressive. To find one, start with our directory and find a Black dermatologist near you. If your melasma started with pregnancy, birth control, or hormone therapy, that is worth raising too, and our guide to thyroid-related skin and hair changes in Black women covers another hormonal driver worth ruling out.
Frequently asked questions
Does melasma go away on its own? ▼
Sometimes. Melasma triggered by pregnancy or birth control can fade within months after the hormone shift ends. Melasma driven mainly by sun and heat usually does not resolve without treatment and sun protection, and it tends to flare and fade for years. There is no permanent cure, so the goal is control.
What is the difference between melasma and dark spots? ▼
Dark spots are post-inflammatory hyperpigmentation, the marks left by acne, eczema, razor bumps, or injury. They sit where the skin was inflamed and are usually scattered. Melasma is symmetric, mirrored on both cheeks or across the forehead, driven by sun, heat, and hormones, often sits deeper in the skin, and is harder to treat.
Why does my regular sunscreen not control my melasma? ▼
Most chemical sunscreens block UV but not visible light, and visible light is a major melasma driver on darker skin. You need a tinted, iron-oxide broad-spectrum sunscreen, because the iron oxides block visible light that ordinary SPF lets through. Untinted sunscreen often is not enough on its own.
Can a laser get rid of my melasma? ▼
Lasers are a later step, not a first one, and on Black and brown skin they can backfire, often causing rebound darkening and new post-inflammatory hyperpigmentation. If a laser is used, it should be low energy, paired with topicals and sun protection, and performed by a clinician experienced in skin of color.
Is hydroquinone safe for Black skin? ▼
It is effective when used carefully and time-limited under a dermatologist. The danger is long-term unsupervised use, especially at high strength, which can cause exogenous ochronosis, a blue-black discoloration that mostly affects people of African descent and is hard to reverse. Never use imported high-strength skin-lightening creams.
Does oral tranexamic acid work for melasma? ▼
Yes, for stubborn or widespread melasma. Randomized trials and meta-analyses show low-dose oral tranexamic acid reduces melasma severity when added to topicals and sun protection. It is prescription-only and carries a small clotting risk, so it is not for people with a history of blood clots and requires a clinician's screening.
