Laser Hair Removal and the Laser Process

Laser hair removal treatment involves targeting intense light at a specified wavelength into the skin. Laser hair removal damages dark matter by selectively heating hair follicles, which are dark pigments in the skin. Laser hair removal does not damage lighter skin.

Laser hair removal materials used:

· Carbon – Before laser hair removal, a carbon-based lotion is rubbed into the skin. When irradiated by an Nd:YAG laser, the carbon causes a shock wave that damages nearby cells.
· Hemoglobin - occurs naturally in blood and absorbs wavelengths during laser hair removal from argons, ruby, alexandrite and diode lasers. It minimally absorbs the Nd:YAG laser. · Melanin - occurs naturally in the skin and gives color to skin and hair. Eumelanin melanin makes hair brown or black and pheomelanin melanin makes hair blonde or red.

Different materials create different lasers for laser hair removal and include:

· Argon
· Ruby
· Alexandrite
· Pulsed diode array
· Nd:YAG
