The Q-switched laser is used to remove unwanted brown spots, sun freckles, or tattoos from your skin. The laser energy pulse, which is in billionths of a second, releases the pigment into the skin so it can be naturally reabsorbed and disposed of by the body.The laser energy feels like many tiny hot dots on your skin. The discomfort is greatly reduced (but not eliminated) by a stream of cold air directed at the spots during treatment. Tattoo removal without anesthetic is very painful, so we always attempt to anesthetize the area before performing tattoo removal.
