Laser & light technology is being used for an increasing number of cosmetictreatments. Examples include hair reduction, skin rejuvenation wrinkle reduction, treatment of acne, removal of pigmented blemishes, & treatment of vascularlesions. The new Xlase, combined Nd:YAG & Calibrated Pulsed Light is develo-ped according to newest scientific research results. LIGHT ABSORPTION PRODUCES HEATThe concept behind the use of light to treat skin tissue is that light that is absorbedby tissue generates heat. By using specific colors (or wavelengths) of light to treatspecific parts of the skin we can target & therefore treat a distinct part of theskin & spare surrounding tissue. Light can pass completely through non-absorbing tissue & effect subsequent tissue that absorbs its energy & therebyproduces heat.
