Definitions for "Laser hair removal"
A hair removal technique in which a specified wavelength of light is delivered from a hand piece into the skin, where it targets dark material (usually the pigment in hair). This is intended to cause thermal and/or mechanical damage to a hair follicle while sparing surrounding tissues. Light skin and dark hair are the best combination for laser hair removal. The more closely your skin tone matches your hair color, the less likely you are to benefit from laser hair removal.
a new treatment design to remove and prevent further growth of hair by using a laser to deactivate hair follicles.
A simple cooling tip comes in contact with the surface of the skin before delivering a high speed of light.
Epilation performed by laser was performed experimentally for about 20 years before it became commercially available in the mid 1990s. Laser and light-based methods are sometimes called phototricholysis or photoepilation.
