There are many causes of skin discoloration, and while most are temporary, there are still a few causes for permanent skin discoloration. While some causes can be avoided, such as not picking at pimples to prevent acne marks or wearing sunscreen to prevent sun spots, there are still many conditions that leave the skin discolored and irregular. Pregnancy, for example, will often cause brown spots and hyperpigmentation on the face, while burns or skin trauma will also leave scars behind.
Skin discoloration happens after damage to the skin cells where melanin is held. A person’s natural skin color is determined by the amount of melanin found in their skin cells, and when trauma occurs, the damaged skin cells will either increase or decrease the amount of melanin that shows through the skin’s surface. Fortunately, even permanent skin discoloration can be treated.
Laser skin rejuvenation is one of the leading treatments to get rid of discolorations caused by the sun, aging, scars, freckles, and more. It works by getting rid of damaged cells through the process of creating microscopic wounds within the layers of the skin. The surrounding healthy skin cells will then begin healing these wounds by producing healthy skin cells—ones that don’t have discolored melanin. The results are the elimination of the targeted skin imperfections.
