LED treatments work by using an array of bright light-emitting diodes (originally developed by NASA!) that send low-level light energy into the deeper layers of the skin. Red light LED stimulates cellular activity, including the fibroblasts that produce collagen, which gives young skin its plump look.

Melanin is considered the primary chromophore for all hair removal lasers currently on the market. Melanin occurs naturally in the skin and gives skin and hair their color. There are two types of melanin in hair. Eumelanin gives hair brown or black color, while pheomelanin gives hair blonde or red color. Because of the selective absorption of photons of laser light, only hair with color such as black, brown, or reddish-brown hair or dirty blonde can be removed. White hair, light blonde and strawberry blonde hair does not respond well. Laser works best with dark coarse hair. Light skin and dark hair are an ideal combination, being most effective and producing the best results.
