Thermage FLX

How it works

Thermage FLX, made by Solta Medical, delivers monopolar radiofrequency through a treatment tip pressed against the skin. Current passes through the tissue and creates heat from resistance, warming the dermis and the tissue beneath it. The device cools the surface while this happens. The heat is intended to tighten existing collagen at once and to stimulate remodeling over the following months, which is why changes are described as gradual.

Good to know

• The catalog lists it as monopolar RF, where current travels through the body to a return pad.
• Different tips are used for the face, eye area and body, which changes the energy and pattern.
• It is considered for mild to moderate laxity, skin texture and contour on the face, neck and body.
• Heat is felt during treatment and mild redness can follow; results vary by person.

Where Thermage FLX sits among similar devices

In this concern map, Thermage FLX is the reference point for monopolar RF. Its heating is broad and fairly deep but continuous, unlike focused ultrasound, which concentrates heat in small points. People with general looseness and some surface texture concern often see it listed beside ultrasound lifting for that reason.

Among other radiofrequency devices, differences come from frequency, tip design, cooling method and how treatment is delivered. Monopolar units like this one are not the same as microneedle RF, which breaks the skin surface with fine needles and is aimed more at scars and pores. Skin thickness, goals and tolerance for heat all shape the choice.
