Just about everyone has a few obvious brown spots on their skin. Freckles, age spots, liver spots, and various birthmarks are jut a few of the commonly known marks, generally referred to as pigmented lesions.
Dark or light complexioned, we all have varying amounts of melanin. Pigmented lesions are dark in color simply because melanin is abnormally concentrated in one area of the skin. High concentrations of melanin can be due to various factors. Some types are present at birth, but most occur with age or as a result of overexposure to the sun’s damaging rays. Pigmented lesions can be successfully lightened or removed with modern laser technology. A laser removes pigmented lesions with the energy of light.
A laser is designed to produce one or more specific light wavelengths which are absorbed by the pigment. Pigmented lesions are either lightened or removed when the laser passes through the skin but is absorbed by abnormal concentrations of melanin. The rapid absorption of light energy causes the melanin to destruct to a point where the melanin concentration is reduced, leaving the treated skin looking uniform in color and texture.
The YAG laser is one of the most advanced lasers available today for the removal of pigmented lesions. This laser provides the appropriate wavelength of light for absorption by abnormal melanin concentrations. The Nd:YAG also delivers the light in very short, high intensity pulses for maximum melanin destruction. The use of this specific combination of wavelength and rapidly pulsed light results in minimal damage to normal skin while providing maximum abnormal melanin removal.
