20-Second Answer
The 3 established, editor-vetted options for this concern:
Melasma is not just a dark spot that needs a stronger brightening serum. It behaves more like a pigment system that has become oversensitive. Melanocytes, the cells that make pigment, start reacting too strongly to light, heat, hormonal signalling, and inflammation. That is why melasma can fade, then come back after one sunny week, one heat-heavy holiday, or one overconfident peel. It often shows up in broad, soft-edged patches rather than isolated dots. The pattern is usually symmetrical, which is one clue that it is not the same as PIH. PIH often follows a known injury or breakout; melasma has more of a background-driver pattern, where the skin keeps receiving signals to make pigment even without a visible wound. The main misunderstanding is that melasma can be blasted away. Aggressive lasers and harsh peels can make it worse, especially on medium, pigment-prone skin. The stronger strategy is less dramatic: high UVA protection, visible light protection when needed, heat awareness, steady pigment-regulating ingredients, and professional guidance for stronger options. Melasma rewards consistency and punishes chaos.
Find Your Cause
Not every cause is treated the same way — find the one that matches you.
UV and visible light
Light exposure signals melanocytes to produce more pigment; visible light can be relevant in medium, pigment-prone skin.
Heat exposure
Heat can worsen pigment signalling even without a classic sunburn.
This one's more about routine than a specific product — gentler handling helps more than any ingredient.
Hormonal shifts
Pregnancy, contraceptives, and hormonal changes can be associated with melasma patterns.

Inflammation
Irritated skin is more likely to produce uneven pigment, especially after harsh treatments.
Genetic tendency
Some people have melanocytes that are simply more reactive; that is unfair, but useful to know."
