Thermage FLX uses monopolar radiofrequency (RF) to tighten skin and stimulate collagen, reducing laxity for smoother, firmer skin — without surgery
Thermage FLX is a monopolar radiofrequency technology that delivers heat energy evenly into the dermis to trigger collagen contraction and new collagen production, firming and smoothing the skin and reducing laxity on the face, around the eyes, jawline, neck and body. It suits those with early skin laxity who prefer a non-surgical option. Its highlight is a single session with progressive results, plus the AccuREP system that tailors energy to each person's skin.
The treatment tip emits monopolar RF that heats deep into the collagen layer, while surface cooling keeps the skin safe and more comfortable. The heat makes collagen contract immediately and rebuild over the following months, so skin keeps firming.
Duration: 45-90 minutes depending on area
Downtime: Minimal — slight redness/swelling for a few hours
Suitable for: Early laxity, softening jawline, under-eye laxity, wanting non-surgical lifting
Skin can feel firmer right after treatment and continues to improve as new collagen forms over 2-6 months, with results typically lasting 6-12 months depending on skin and age. Results vary by individual.
Thermage uses RF to heat the dermis to tighten skin and texture, whereas Ulthera/Ultraformer use focused ultrasound (HIFU) reaching the SMAS layer to lift the facial framework. Many cases combine both for complete lifting and tightening; the doctor advises based on your skin.
