Dark spots, explained without the jargon

A dark spot is your skin remembering an injury. A breakout, a scratch, a sunburn, an ingrown hair. In response, pigment cells make extra melanin at that spot, and the mark stays after the injury heals.

On melanin-rich skin, those cells are simply more responsive, so the marks show up faster and stay longer. That is not damage or a flaw. It is how the skin is built. It does mean prevention and patience matter more.

• Post-inflammatory marks. The flat, darker patches left behind by breakouts or irritation. The most common kind, and the most responsive to a good routine.
• Sun spots. Small, defined spots on the areas that see the most light: cheekbones, forehead, backs of hands.
• Melasma. Larger, symmetrical patches, often on the cheeks and upper lip, tied to hormones and heat as much as sun.

Every approach comes down to the same two moves: stop new pigment from forming, and speed up the turnover of skin that already carries it.

Sunscreen, every day. UV is the signal that tells pigment cells to work harder. Without daily SPF, everything else is running uphill.

A brightening serum. Look for ingredients that quiet pigment production, like niacinamide, vitamin C, or licorice root, applied consistently to the whole face rather than dabbed on spots.

Gentle exfoliation. Once or twice a week, not daily. Over-exfoliating causes irritation, and irritation causes more pigment.

Picking. Scrubbing. Switching products every two weeks. Anything that stings on contact. Irritated skin makes more pigment, so the harsh option almost always makes the spot darker.
