The hair is mainly composed of keratinocytes that synthesize keratin, and melanocytes which are responsible for the production of melanin. In photo-depilation, intense pulsed light is absorbed by the melanin (coloured pigment) contained in the hair. This is then channelled to the “root” (hair shaft, hair follicle, epithelium and matrix). When the light meets a chromophore, it is converted into heat; the thermal effect destroys the germ cells responsible for hair growth. These are located approximately 4-6mm under the skin. Hair acts as a conductor of energy to these cells, therefore, the hair must be in the “anagen” phase (phase at which the bulb and the hair shaft are attached to the root). Light skin contains a small amount of melanin but by using a wavelength of 620-1200nm the melanin in the hair absorbs the light. Multipulse is an important parameter that reflects the TRT (thermal relaxation time) of the skin which is relative to the target chromophore which avoids the risk of burns caused by single flashes that are too long.

Excellent results, 60% of hair missing after the third session
Using an Nd-YAG laser for hair removal provides a temporary result contrary to treatment with pulsed light.
Treatment time: 8 to 10 sessions are required at intervals of about 4 to 6 weeks depending on the zone treated. HR: 620 - 1200 nm
