Reality star Kim Kardashian was on national TV today about TRIA, an at-home laser hair removal device that permanently reduces hair growth with very little pain. Kardashian has often joked that being half Armenian, managing excess hair growth has always been difficult. She tells Rachael that laser hair removal was the best invention for her, and she loves being able to do it in the comfort of home.

The latest TRIA device offers 5 energy settings, allowing users to customize their treatment depending on hair color and thickness. Just as in professional settings where aestheticians have their choice of a wide range of hair removal settings, the TRIA gives you the same choice at home so that you can best remove the unwanted hair.

The TRIA Laser Hair Removal device uses that same laser technology to deliver results like those of professional devices so you never have to worry about shaving or razor burn again. The device costs $495 and can be purchased without a prescription. It's FDA approved for hair reduction but is not for those with medium to dark brown skin tones. It works best on those with lighter skin and dark hair, and won't work on gray, blond or red hair.
