TRIA Beauty helps every woman find her inner esthetician. The company's two medical devices, used to zap unwanted hair and clear up acne, are designed for at-home use, so no more costly trips to the medical spa. Its TRIA Hair Removal Laser is a handheld device that uses laser light to stunt hair growth, while its Skin Perfecting Blue Light device treats acne by using blue light therapy to kill underlying bacteria. TRIA Beauty's devices are sold online, on television via QVC and infomercials, and at high-end retailer Bloomingdale's. A third device, the Skin Rejuvenating Laser, used to reduce the appearance of facial wrinkles, is under development. TRIA Beauty filed and withdrew an initial public offering in 2012.
