Non-Surgical · Radiofrequency · Device Comparison
Two radiofrequency devices held at one clinic, aimed at different problems
Gangnam, Seoul | Board-certified plastic surgeon, Dr. Jonghwan Choi

InMode or Thermage
The short answer
Both are radiofrequency devices held at Rewind Plastic Surgery, and the clinic's records describe them doing different work. InMode delivers bipolar current through two handpieces: FX, aimed at fat under the chin and in the cheeks, and Forma, aimed at skin firmness. Thermage FLX is a monopolar device that heats the dermis to contract collagen and stimulate new collagen, with lifting and skin texture among its recorded effects. A face with surface fat to reduce points toward InMode FX. A face whose complaint is skin laxity alone can be a case for Forma or for Thermage, decided at the examination.
Sources: Rewind's Korean device documentation and published price list. Session length and comfort protocols are published for neither device and are not estimated here.
The quickest way to read the comparison is to ask whether fat is part of the problem. Thermage's record lists firmer, smoother skin and softer fine lines, and it names no fat reduction. InMode's record names fat reduction first, through FX, and firmness second, through Forma.
The two are also sold differently. Thermage FLX is listed as one face plan at a fixed shot count. InMode is listed per handpiece and per session, so its total depends on how many visits the doctor recommends.
Four differences
Each card draws on the clinic's own device record, price list or written aftercare. Where the record says nothing, nothing is claimed.
Mechanism
Radiofrequency devices differ mainly in the path the current takes. That path decides how deep the heat goes and which tissue absorbs it.
Current runs between two electrodes on the InMode handpiece, so the heated zone sits in the tissue directly beneath them. That is what allows one handpiece to be built for fat and another for the dermis.
In a monopolar system the current leaves the treatment tip and travels toward a return pad placed on the body, spreading heat through the dermis beneath the tip. Rewind's record describes collagen contracting and fibroblasts being stimulated to form new collagen.
Forma and Thermage both aim at collagen in the dermis. Early multicentre work on monopolar radiofrequency around the eyes, and later studies of low-energy, multiple-pass technique on the lower face, describe the tightening response Thermage is associated with.
Only InMode, through FX, carries a fat-reduction purpose in the clinic's record. A patient whose fullness is fat, treated with Thermage alone, is working on the skin over the problem and leaving the problem in place.

Choosing
Both devices are on the same floor at Rewind, so the recommendation has no reason to favour either one. It follows the face in the chair.
Where the cheeks or the area under the chin carry fat close to the surface, InMode FX is the device the record assigns to it, often paired with Forma when the skin is also loose.
Reducing fat in a face that has little of it can leave it looking drawn. Here the conversation turns to skin-directed options, and Thermage FLX or Forma alone is weighed against the examination findings.
When the jaw line has softened because tissue has descended, neither device lifts it back. As a board-certified plastic surgeon, Dr. Choi explains what a surgical lift would involve and leaves the choice with you.

Rewind occupies the fourth and fifth floors of the Richro Building in Apgujeong, Gangnam, Seoul, and both devices are used there by appointment. The clinic opens Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and Saturday from 10:00 to 16:00, and is closed on Thursday and Sunday.
If you are unsure which device you want, say so when booking. The consultation covers both, and the plan is written for one, the other, or neither.
Pricing
The two devices are priced on different units, so compare the plan you would actually have: an InMode course of the recommended length against a single Thermage face plan.
List rates before value-added tax. InMode lines are per session, multiplied by the count the doctor recommends; the Thermage line is one plan at the shot count shown. Rewind also offers an elasticity package built around Thermage at a higher shot count, quoted at the consultation.
Fit
After treatment
Rewind issues separate written instructions for each device, and the Thermage sheet asks for more patience.
For both devices the clinic's record gives a durability of six months to more than a year, varying with skin and plan, so longevity is no reason to prefer one. Reported radiofrequency risks include burns, blistering and altered sensation. Declare implanted electronic devices, pregnancy and earlier treatments in the area.
At Rewind, one board-certified plastic surgeon carries every case — from the first consultation to the final follow-up. Because a face is a story, and a story deserves a single author.

Scientific evidence
Two papers study monopolar radiofrequency tightening, around the eyes and on the lower face; one tests selective radiofrequency heating of fat; and one reviews radiofrequency for skin laxity. They describe other devices, settings and patients, and none compares the two devices as used at Rewind.
