Thermage FLX is the newest generation of the original Thermage system, built by Solta Medical. It uses monopolar radiofrequency energy to heat the collagen-rich layers of skin beneath the surface. That heat does two things at once: it immediately contracts existing collagen fibers for a subtle tightening effect, and it stimulates new collagen production over the following months for progressively firmer, smoother skin.
Unlike lasers that target pigment or surface texture, Thermage FLX works on skin structure which is why it’s often called a “non-surgical facelift.” Built-in cooling and vibration (ComfortPulse Technology) keep the treatment comfortable while the RF energy does the work underneath.
Most clients need just one session a rarity in aesthetic medicine, where most RF and laser skin tightening treatments call for a series.
Thermage FLX is one of the most versatile skin tightening treatments available, and it’s the only FDA-cleared non-invasive option for the delicate eyelid area. Popular treatment areas include:
If your primary concern is a specific injectable or filler need instead, our dermal filler treatments or wrinkle relaxer services may be a better fit many clients actually combine both for a fuller rejuvenation plan.
Compared to surgical facelifts, Thermage FLX requires no incisions, no anesthesia, and no recovery time, you can return to normal activities the same day.
During treatment, you’ll feel alternating cooling and brief heating sensations as the device passes over your skin, most clients describe it as warm rather than painful. Afterward, mild redness or a sunburn-like feeling is common and usually resolves within a day or two. There’s no peeling, no bruising, and no need to plan around downtime.
Results timeline:
Most clients tolerate it well thanks to ComfortPulse cooling and vibration technology. It's typically described as a deep warming sensation, not sharp pain.
Sessions usually run 45–90 minutes depending on the treatment area size.
Thermage FLX works best for mild to moderate skin laxity. It's safe across all skin tones since it targets heat, not pigment. A consultation with our team will confirm if it's right for your goals.
Thermage FLX focuses on skin tightening and collagen renewal, while our body sculpting services target fat reduction and muscle tone. Many clients pair the two for a more complete result.
