In most cases, yes — without consistent sun protection and a maintenance protocol, melasma typically recurs over months. This isn't a failure of the treatment; it's the underlying biology. Melasma is driven by pigment-producing cells (melanocytes) that respond aggressively to UV light, visible light, heat, and hormonal triggers. The treatment quiets that response while you use it; the underlying tendency remains.
What sustained results require:
- Daily broad-spectrum SPF 30 or higher — every day, including overcast days and indoor days near windows. Mineral sunscreens (zinc oxide and titanium dioxide) with iron oxides also block visible light, which contributes to melasma in skin of color.
- A maintenance formula after the active treatment phase. A board-certified dermatologist team design a non-hydroquinone maintenance regimen to hold the pattern between active cycles.
- Trigger awareness — heat exposure (saunas, hot yoga, sustained outdoor activity), hormonal changes (pregnancy, oral contraceptives, perimenopause), and certain medications can re-trigger melasma. Not all triggers are avoidable; awareness helps you and your dermatologist plan around predictable flare windows.
Patients who stop both the active formula and consistent sun protection usually see recurrence within 3 to 6 months. Patients who maintain sun protection and a maintenance formula often hold their gains long-term.
