Quick answer
What Is Thermage FLX?
Thermage FLX is a non-invasive skin tightening treatment that uses monopolar radiofrequency (RF) to heat the deep dermis and underlying tissue in a uniform layer. The heat contracts existing collagen and stimulates new collagen, so skin gradually becomes firmer and smoother.
Each pulse is paired with cooling spray and vibration to protect the skin surface and improve comfort, and the system adjusts energy shot by shot for consistent heating. Different tips are used for the face, the delicate eyelid area and the body.
Thermage FLX works across the whole skin surface rather than at focused points, so it is well suited to overall firmness, fine crepiness and early laxity. For deeper structural lift, it is often paired with Ultherapy or Titanium.
