How Does it Work? A laser light is passed over the pigmented skin, microscopically shattering the pigment into tiny particles which are more easily processed and eliminated by the body. Most patients undergo a 10-20 minute treatment. A mild to moderate irritation of the overlying skin is to be expected for a few days to a week, depending on the depth and amount of pigment to be removed. Does it Hurt? The Nd:YAG laser treatment causes a slight sting. Anesthetics are not needed for most patients; however those with very sensitive skin may apply a numbing cream 30-45 minutes before the procedure if desired Health News
