TempSure Envi skin tightening is a pain-free treatment that Dr. Kothandaraman performs in the office. During the Envi therapy, she waves the Envi handheld RF device across your chosen treatment areas. This device gently heats the tissue just under the surface of the skin, triggering your body’s natural collagen production and reducing the appearance of wrinkles. Your Envi treatment should take no more than 45 minutes, which makes it a perfect skin tightening treatment to fit into a busy schedule.
