Age spots, freckles, brown spots and birthmarks (Nevus of Ota or café-au-lait marks) can be treated with the Revlite Q-switched Nd:YAG laser. The Revlite laser effectively targets abnormally high concentrations of melanin (or pigment) in the skin, leaving normal colored skin behind. Melanin is what gives skin its color and the amount of melanin in one's skin determines if you have a light or dark complexion. High concentrations of melanin can be present at birth as pigmented lesions, but most are the result of over exposure to the sun's damaging ultraviolet rays.
The Revlite is most commonly used for removing brown age spots, or "liver spots". The Revlite laser has a specially designed wavelength of light energy, which is absorbed by the pigmented lesion, destroying it. Because of this special wavelength, most pigmented lesions are removed within one to two treatments. Some deeper lesions will require more treatments.
