Lasers can be used to remove tattoos and birthmarks from the skin by destroying cells with a particular colour, such as cells in red birthmarks. A laser beam can also be used to reduce the severity of scars and the effects of aging, such as wrinkles, by removing the top layer of cells to smooth the skin. The beam of high-intensity light is precise and does not cause damage to surrounding cells.
