Lumenis sheds new light on skin problems. The firm makes medical devices that use intense pulsed light (IPL), lasers, and radiofrequency technology to treat aesthetic problems (lesions, wrinkles, acne, etc.) and a wide range of other conditions. Its proprietary IPL technology converts the light source into thermal energy. Aesthetic systems include LightSheer to remove hair and rejuvenate skin and M-22 used to treat fine lines, wrinkles, scars, and discoloration. The UltraPulse and VersaPulse systems are used for urology, neurology, and ENT (ear, nose, and throat) surgical procedures. The firm also makes ophthalmic laser products for vision correction. Lumenis was acquired by XIO Group for $510 million in 2015.
