Melasma is a long-term pigment condition, not a stain that scrubs off, and in deeper skin tones the order of treatment matters far more than its strength. The skin most prone to melasma is also the easiest to injure, so heat and strong lasers frequently make it worse. What genuinely helps is daily protection from visible light, a prescribed topical plan, and patience measured in months. Melasma can be faded and controlled. It cannot currently be cured, and anyone promising permanent clearance in a handful of sessions is selling you something.
Why deeper skin tones behave differently
Melasma appears as brown to grey-brown patches across the cheeks, forehead, upper lip and jawline. The American Academy of Dermatology notes that people of Latin American, Caribbean, Asian, Middle Eastern, Mediterranean and African descent develop it more often, because their pigment-producing cells are more active to begin with (AAD).
That reactivity is also the problem. In Fitzpatrick skin types IV to VI, almost any inflammation can leave post-inflammatory hyperpigmentation on top of the melasma you were treating: a burn, a peel taken too deep, a laser pass at the wrong setting, even a picked spot. In lighter skin, a treatment that goes too far leaves redness. In deeper skin it leaves pigment that can outlast the original patches.
Ordinary sunscreen is not enough
Most people with melasma know about UV. Far fewer know that visible light, the light you can actually see, drives pigment in darker skin specifically, inducing melanogenesis with a more sustained darkening in deeper phototypes than UVA alone (PMC).
Clear, untinted sunscreens filter UV. They do not block visible light. Tinted formulations containing iron oxides do. In a randomised, investigator-blinded trial following melasma patients through a summer, the tinted group showed a significant reduction in the colour difference between affected and unaffected skin, and the untinted group did not (PMC).
In practical Florida terms: a tinted mineral sunscreen with iron oxides, SPF 30 or higher, every morning and reapplied through the day, plus a wide-brimmed hat and shade at midday. A tint that matches your skin is not a cosmetic detail here. It is the active part.
One honest limitation: the evidence that phone screens and indoor lighting meaningfully worsen melasma is much weaker than blue light marketing suggests. Daylight, including sun through a car window, is what to plan around.
Triggers you can change, and triggers you cannot
Pregnancy, combined oral contraceptives and hormone-containing devices are common triggers, as is heat itself. Thyroid disease appears more often in people with melasma than in the general population, so it is worth checking. Perimenopause shifts the picture too, and our piece on perimenopause and menopause covers that hormonal context.
Said plainly: removing a trigger does not reliably clear melasma. Plenty of women stop the pill or finish a pregnancy and the pigment stays. Treat triggers as one lever, not the answer.
What actually has evidence behind it
Topical combination therapy is the best-supported first-line treatment. The triple combination of hydroquinone, a retinoid and a mild topical steroid has the strongest evidence base among the topical options (review). It is prescription-only in the United States and meant for supervised courses, not indefinite use. That supervision is the point in deeper skin, because prolonged unsupervised hydroquinone is associated with exogenous ochronosis, a blue-grey discolouration harder to treat than the melasma was.
Non-hydroquinone topicals such as azelaic acid, cysteamine, topical tranexamic acid and niacinamide are reasonable, particularly for maintenance between courses. The evidence is thinner and results are slower, worth knowing before you judge them at four weeks.
Oral tranexamic acid is used off-label and has genuine support. A systematic review and meta-analysis found a significant reduction in melasma severity scores while flagging high heterogeneity between trials, small samples and generally low study quality (PMC). It is not FDA approved for melasma, and it is not appropriate with a history of blood clots, a clotting disorder, smoking while on estrogen, recent surgery or pregnancy. That needs a real history before a prescription, not a checkbox.
Lasers: the part many clinics leave out
In darker skin, lasers are not first-line for melasma. A review in the Journal of Cutaneous and Aesthetic Surgery concluded that they cannot be recommended as first-line therapy in darkly pigmented skin, citing rebound hyperpigmentation after fractional treatment and post-inflammatory pigmentation that took a mean of 3.2 months to settle (PMC).
Results also tend to be temporary, and pigment commonly returns, sometimes darker. Intense pulsed light carries particular risk in Fitzpatrick IV to VI because it targets pigment broadly rather than selectively.
That does not make energy devices useless. It means they come after photoprotection and topicals, at conservative settings, from someone who treats your skin type routinely. The same logic applies to microneedling, where depth and post-procedure inflammation matter more in deeper skin.
Red flags: see a clinician, not a shop
- A single dark patch that is growing, changing shape, asymmetric, itching or bleeding. That is not melasma and needs assessment.
- Blue-grey or speckled discolouration developing after months of a lightening cream.
- Blistering, crusting or a burn after any device, peel or treatment.
- Any lightening product bought overseas, unlabelled, or with an ingredient list you cannot read. The FDA warns that some contain mercury, and that over-the-counter hydroquinone products are unapproved new drugs that should not be on the US market (FDA, FDA).
- New pigment alongside fatigue, unexplained weight loss, dizziness or salt craving, which can point to an adrenal cause.
What a realistic plan looks like
Judge progress at eight to twelve weeks, not at two. Expect maintenance rather than a finish line, and some darkening each summer however well the winter went. The people who do best treat photoprotection as a daily habit and the actives as supervised courses.
At MetaHealth we see melasma across the full range of skin tones in Deerfield Beach, in English, Portuguese and Spanish, and we would rather slow a plan down than trade a few weeks of speed for a year of post-inflammatory pigment. There is more on our aesthetics page. Topical plans and follow-up work by telehealth anywhere in Florida, and anything involving a device needs an in-person visit.
