Thermage (monopolar radiofrequency)

Monopolar radiofrequency (MRF) · ThermaCool · Thermage FLX

Recovery: 0–2days
Pain: Moderate
Sessions: 1 session
Type: Non-surgical

What it is

A non-invasive device that heats the deeper skin (dermis) with monopolar radiofrequency while protecting the surface, so collagen contracts and remodels. It is used for mild to moderate skin laxity and wrinkles. A 2022 systematic review found measurable improvement in laxity, with mostly minor, short-lived complications.

Who it’s for

Adults with mild to moderate skin laxity. In a survey of Korean dermatologists, people in their 40s were thought to respond most, and skin thickness was the main factor in response.

How it’s done

The skin is cleansed. The treatment tip delivers heat in several passes while the surface is cooled, and your feedback on heat helps set the energy.

Questions people ask

How is Thermage different from Ulthera?

Both are non-surgical heat-based devices. Thermage uses radiofrequency to heat the dermis, while Ulthera uses focused ultrasound at set depths. A doctor chooses based on skin and goals.

When will I see results?

In a 2007 survey of 5,700 treatments using a lower-energy, multiple-pass method, 87% showed immediate tightening and 92% had tightening at six months.

Does it hurt?

Heat is felt. In the same survey, 5% found the multiple-pass, lower-energy method too painful, compared with 45% under the older high-energy method.
