Thermage FLX is a noninvasive skin rejuvenation treatment that’s FDA cleared to treat fine lines and wrinkles, and to improve the appearance of cellulite. The device is also commonly used for skin tightening on the face and body. 

The Thermage FLX system works by using radiofrequency (RF) energy to heat the skin’s dermis, under the surface layer. This contracts existing collagen fibers, providing subtle skin firming right away. It also stimulates collagen growth, a cellular process that doctors call collagen synthesis. This makes skin firmer, tighter, and more youthful-looking over three to six months, as the new collagen forms.

Most Thermage FLX treatments focus on the upper and lower eyelids, crow’s feet, along the jawline, and the neck. This versatile treatment can also treat mild skin laxity on the stomach, arms, backs of the hands, thighs, knees, and butt.

Used as a cellulite treatment, it boosts circulation and stimulates collagen synthesis, which makes skin look smoother and less dimpled.
