Melasma may be the most frustrating pigment condition in aesthetics: brown patches, usually across the cheeks, forehead, or upper lip, that resist treatments that work fine on other dark spots, and worsen with treatments that seem like the obvious choice. Understanding why is the difference between clearing it and chasing it.
Why melasma is different
Ordinary sun spots are localized sun damage. Melasma is a condition: pigment cells that have become chronically overactive, driven by a mix of genetics, hormones (it’s often triggered by pregnancy or birth control, hence “the mask of pregnancy”), and light exposure. Crucially, the trigger isn’t just UV. Visible light and heat provoke it too.
That’s the trap. The pigment-destroying tools that erase sun spots, like IPL and aggressive lasers, deliver heat, and heat tells melasma to make more pigment. Patients regularly arrive at good providers after a laser package elsewhere left them darker than they started.
What actually works
The winning approach is low-heat, repeated, and layered:
- Prescription topicals are the true first line: hydroquinone courses, tretinoin, azelaic acid, and increasingly oral or topical tranexamic acid from a prescriber. In-clinic treatments amplify these; they don’t replace them.
- Chemical peels, gentle and repeated, lift pigment without provoking heat. Expect a series with gradual fading.
- Microneedling creates channels that dramatically improve topical penetration and remodels pigment-laden skin with minimal thermal load.
- Cautious, low-energy laser protocols have a role in experienced hands. The emphasis is on experienced, because energy settings that are routine for other conditions rebound melasma.
And underneath everything: daily tinted mineral sunscreen. The iron oxides in tinted formulas block the visible light that clear sunscreens miss. For melasma specifically, this is not optional skincare advice. It’s the treatment’s foundation.
How to choose a provider
Ask one question: “How do you treat melasma differently from sun spots?” A provider who answers with heat caution, topical-first sequencing, and sunscreen requirements treats melasma for real. A provider who quotes you the same IPL package they’d sell for freckles is about to make yours worse.
