The Tria Hair Removal Laser claims to be the first DIY machine of its kind & uses light-based laser beams previously only available at salons. The handheld, cordless device, which comes in either green or fuchsia, uses a pulse counter & diode laser technology to disable hair follicles. It only works when applied to the right skin tone. The company recommends it for those with ‘light to medium’ skin tones. Really fair people or medium to dark people should not use as may damage. 375pds.
