The laser beam precisely and evenly scans a thin layer of skin. Removing the surface layer of skin removes some of the cells damaged by the elements and the sun. The dead cells that are removed are replaced by new cells. The result is younger-looking skin and a more even skin tone.
Since only the top layer of your skin is treated, most patients will see a noticeable improvement in texture and evenness of skin tone as soon as the skin heals, which is about 3 to 4 days.
