radio frequency / skin tightening Skin Tightening for ALL Skin Types Our Liftron TherMatrix is the only device to use Mono & Bi-polar coupled radiofrequency (RF) energy that enables deep, uniform, volumetric heating that other systems simply can’t deliver. Liftron TherMatrix can reach deep into the under layer of the skin called the dermis. This heat causes new collagen creation, which makes the skin look firmer and tighter and improves the overall texture of the skin. This treatment is fast and painless with no downtime and is safe for all skin types.
