Why does melasma keep coming back after laser treatment?

Because melasma is not a pigment problem that sits still. It is a hormonally driven, heat sensitive condition where the pigment producing cells are overactive and stay that way. A laser can clear what is visible today. It does nothing to the underlying signal telling those cells to keep producing.
Heat itself is a melasma trigger
There is a second problem that most people are never told. Heat itself is a melasma trigger. Aggressive resurfacing and especially IPL (intense pulsed light, which is light energy rather than a true laser) can clear the face for three weeks and then bring it back darker than the starting point, because the inflammation from the treatment stimulates the exact cells you were trying to quiet. This is why melasma patients often report their skin got worse at a place that was perfectly competent with everything else.
The approaches that hold are low and slow
The approaches that hold tend to be low and slow. Conservative settings, longer intervals, and a daily home routine doing most of the work. Tinted mineral sunscreen with iron oxide matters more here than untinted, because visible light drives melasma and standard SPF does not block it. Some cases also have a vascular component, where the redness underneath feeds the pigment, and that has to be treated separately or the pigment keeps returning.
Managed, not cured
Realistic framing: melasma is managed, not cured. A good year looks like eighty percent clearance held through summer with maintenance. Anyone promising permanent removal is either being careless or has not treated much of it.
Common questions
Can melasma be cured permanently?
No. Melasma is managed, not cured, because the hormonal signal driving the overactive pigment producing cells persists after any device clears the visible pigment. A good year looks like eighty percent clearance held through summer with maintenance. Anyone promising permanent removal is either being careless or has not treated much of it.
Why did IPL make my melasma worse?
Heat itself is a melasma trigger. Aggressive resurfacing and especially IPL can clear the face for three weeks and then bring the pigment back darker than the starting point, because the inflammation from the treatment stimulates the exact cells the treatment was trying to quiet. This is why melasma patients often report their skin got worse at a practice that was perfectly competent with everything else.
What sunscreen works for melasma?
Tinted mineral sunscreen with iron oxide matters more here than untinted, because visible light drives melasma and standard SPF does not block it. Daily use is part of the home routine that does most of the work between conservative in-office treatments.
LovMedSpa evaluates melasma against skin type and trigger history before selecting an approach, since the wrong device does more damage here than doing nothing. That evaluation happens under the clinical oversight of medical director Dr. Ahmed Elsoury, MD (New York and Connecticut) and Mark Ennett, PhD, CRNA (South Florida), across our Brooklyn, Manhattan, Staten Island, Aventura, and West Farms locations. A consultation is the best way to determine which approach fits your skin type and trigger history.
