Hyperpigmentation after laser treatment is a common problem and occurs more frequently in patients who get tanned easily. Fortunately, hyperpigmentation is not permanent in most cases. This happens because the laser gets attracted to any pigment on the skin, as a result of your skin producing more melanin in response to the heat from the laser. Your body will work to restore homeostasis and the pigmentation will fade in seven to ten days after the treatment. Protect yourself from the sun to prevent the dark areas from getting worse.
