Uneven pigment can differ in depth, pattern, trigger, and response to light-based or exfoliating treatments.
A brown spot, a broader area of uneven color, and discoloration after a breakout may look similar at first glance. Their pattern and history differ, even when all three are described as “pigmentation.”
Notice whether the color is isolated or spread out, and whether it followed a breakout, irritation, or time in the sun.
