Lasers for pigment and the special problem of melasma

Why pigment lasers help some discoloration and can worsen others.

Lasers can be excellent for certain kinds of unwanted pigment and frustrating or harmful for others, and the distinction matters enormously.

Discrete, stable pigment, like sun-induced age spots, often clears well with pigment-targeting lasers that shatter the excess melanin for the body to clear. Melasma, the diffuse, hormonally influenced brown patches usually on the cheeks and forehead, is the cautionary case: it is reactive, and aggressive laser energy can trigger it to rebound darker, making the problem worse. Melasma is generally managed first with gentle topicals and strict sun protection, with very conservative laser settings used selectively and carefully, if at all.

This is why diagnosis precedes treatment. Treating melasma like an age spot with a strong laser is a classic, regret-inducing mistake. In darker skin tones, the risk of post-inflammatory hyperpigmentation from any pigment laser is higher, demanding an experienced operator and conservative approach. The honest message is that pigment lasers are powerful for the right kind of discoloration in the right skin, and counterproductive for the wrong kind, which is exactly why a proper assessment by someone experienced with pigment is worth more than the device itself.
