Melasma is a chronic condition, and unfortunately, there is no permanent cure, including laser therapy. In fact, lasers can sometimes worsen melasma due to heat-induced inflammation.For long-term management, the gold standard is a topical 'triple combination cream' (containing hydroquinone, a retinoid, and a mild steroid) used in cycles under medical supervision. Oral tranexamic acid may also be recommended for resistant cases. However, the absolute key to preventing relapses is strict, daily sun protection. You must use a tinted, broad-spectrum sunscreen (SPF 50+) containing iron oxides daily, as even minimal exposure to sunlight or visible light will trigger its return.
