FX or Forma

What is the difference between InMode FX and Forma?

The short answer

FX and Forma are two handpieces on the same InMode radiofrequency platform, and Rewind's device record gives them separate jobs. FX, which the clinic's Korean menu also calls Mini FX, is directed at fat cells beneath the chin and in the cheeks, to reduce the fat stored there. Forma is directed at the skin, where heat promotes collagen and elastin so the surface firms. Neither uses needles. Both pass current between electrodes held against the skin, the arrangement known as bipolar.

Source: Rewind's own device documentation. Session length, comfort measures and session counts are not published for either handpiece and are confirmed at consultation.

Put plainly, choosing between them means deciding what is making the lower face look heavy. If it is a pad of fat, FX is the handpiece the record points to. If it is skin that has lost its spring, Forma is. If it is both, the two can be run in one appointment, and Rewind lists that pairing as a line of its own.

What neither handpiece does is lift tissue that has descended, or reach fat lying deep beneath the neck muscle. Those findings change the conversation entirely, and the examination exists to catch them before a handpiece is chosen.

Side by side

InMode FX and Forma compared on four points

The clinic's record and price sheet are enough to set the two handpieces next to each other. Where the record is silent, the card says so.

point 01
Target layer
FX: the fat layer beneath the skin. Forma: the dermis, the skin's own structural layer.
point 02
Named areas
FX: under the chin and the cheeks. Forma: described by its effect on facial skin, with no narrower area named in the record.
point 03
Intended change
FX: less fat in the treated area. Forma: more collagen and elastin, read as firmer skin as the dermis rebuilds.
point 04
Body use
FX has a body line on Rewind's sheet, priced per area. No body line is listed for Forma.

Mechanism

How FX and Forma use the same bipolar current differently

Both handpieces send radiofrequency current from one electrode to another across a small patch of tissue. What differs is the tissue each is designed to heat, and so the change each one is meant to produce.

01Shared

Bipolar and needle-free

Current stays between the electrodes on the handpiece, so no return pad is needed on the body and nothing pierces the skin. It is the basis for the same-day return to ordinary activity that the clinic's record describes.

02FX

Heat directed into fat

The record describes FX as destroying fat cells beneath the chin and in the cheeks. Laboratory work on selectively heating subcutaneous fat with radiofrequency has shown fat cells to be vulnerable to sustained heat, the principle a fat-directed handpiece relies on.

03Forma

Heat directed into the dermis

Forma is described as promoting collagen and elastin. Published work on bipolar radiofrequency in the dermis has recorded new collagen and new elastin forming in treated skin, the tissue response a skin-directed handpiece aims for.

04Together

Why the pair can share one appointment

Fat reduction and firming answer two halves of one complaint: a lower face that is both fuller and looser than it was. Running both in one visit treats the two findings together, and the clinic lists that visit as a single item.

The deciding step

Choosing between FX and Forma is a diagnosis

Patients often arrive asking for one InMode handpiece by name. The examination sometimes confirms that choice, sometimes swaps it, and sometimes rules out both.

01Fat

Pinchable fullness points to FX

Fat close to the surface can be gathered between the fingers and moves with the skin. That is the finding the FX handpiece suits, and the doctor checks for it under the chin and along the lower cheek.

02Skin

Loose texture points to Forma

Skin that creases easily and is slow to settle back reads as laxity. Forma's heat is aimed at that layer, so in a face with little fat it is usually the handpiece under discussion.

03Neither

Deep fat or dropped tissue points to a different plan

Fat beneath the neck muscle and tissue that has slid below the jaw line are out of reach of both handpieces. Dr. Choi, a board-certified plastic surgeon, sets out the surgical options in those cases and leaves the decision with you.

Tell the team which handpiece you have read about, and expect the plan to be settled only once the face has been examined. Session length and comfort measures are not published and can be confirmed when booking.

Cost

Pricing

FX and Forma prices at Rewind, single and combined

Each InMode handpiece has its own face line, and the pairing has a third. Knowing which of the three your plan uses answers most of the price question.

InMode FXChin and lower cheek, one session
₩250,000
InMode FormaFacial skin firmness, one session
₩300,000
InMode FX + FormaBoth handpieces, one face appointment
₩550,000

List rates before value-added tax. On the current list the combined line equals FX and Forma added together, so pairing them is a clinical choice with no price incentive either way. Body FX is a separate line quoted per area, and the number of sessions is set after examination.

Fit

Fit

Who suits FX, who suits Forma, and who suits both

Profiles that match a handpiece

  • FX: a soft, pinchable pad under the chin with skin that still has good recoil
  • Forma: a lean face where the complaint is looser, thinner-feeling skin
  • Both: fullness and looseness appearing together along the jaw
  • Any of the three: someone who needs to return to plans the same day

Profiles the doctor will question

  • A lean face asking for FX, where reducing fat risks a hollower look
  • Fullness from fat below the platysma muscle or from the submandibular gland
  • Jowls from descended tissue, which firming alone will not reposition
  • A pacemaker or other implanted device, metal in the area, pregnancy, or active skin infection
After

Aftercare

Aftercare is the same for InMode FX and Forma

Rewind gives one set of InMode instructions whichever handpiece is used, so the choice between them does not change the days that follow.

Day of treatment
A normal day, minus heat
You leave and carry on. Sauna, heavy exercise and alcohol are avoided until the following day.
First one to two days
No rubbing
The area is not scrubbed, pressed or massaged, and harsh cleansers and exfoliants are set aside.
While it settles
Passing effects
Swelling, bruising or itching may appear. The clinic's notes describe them as temporary and resolving on their own.
Afterwards
Durability
The clinic records six months to over a year for its device treatments, depending on skin and plan, with no separate figure for either handpiece.

Radiofrequency literature reports burns, blistering, prolonged redness, altered sensation and, occasionally, unwanted fat loss beneath the treated skin. An analysis of injuries in energy-device practice supports having the examining doctor set the plan. Declare earlier fillers, threads and device sessions before treatment.

Questions

InMode FX or Forma: the questions asked before choosing

Which InMode handpiece targets fat and which targets skin?
FX is the fat handpiece: Rewind's record aims it at fat cells under the chin and in the cheeks. Forma is the skin handpiece, aimed at collagen and elastin in the dermis. Both use bipolar radiofrequency without needles.
Should I have FX, Forma, or both?
It depends on what the examination finds. Surface fat with firm skin points to FX, loose skin with little fat points to Forma, and both findings together point to the combined session. Some faces need neither handpiece.
Is Mini FX the same as FX?
At Rewind, yes. The clinic's Korean device description names the fat mode Mini FX, while the price list shows it as FX. Both refer to the fat-directed handpiece used under the chin and in the cheeks.
Does Forma reduce fat?
Rewind's record describes Forma by its effect on skin, increasing collagen and elastin, and names no fat reduction for it. If fat is part of the concern, FX is the handpiece the record assigns to that job.
Can FX be used on the body?
Yes. Rewind lists body FX as its own item at ₩300,000 per area. There is no body line for Forma. Which body area suits FX is agreed at the consultation.
Is the combined FX and Forma session cheaper?
On the current list the combined line, ₩550,000, equals the FX and Forma face lines added together. There is no discount for pairing and no premium, so the decision rests on your examination alone.
Does the aftercare differ between FX and Forma?
No. Rewind issues one InMode aftercare sheet: avoid saunas and bathhouses, do not rub the area hard, skip harsh cleansers and exfoliants, and expect any swelling, bruising or itching to pass on its own.
Can FX make a thin face look hollow?
Reducing fat where there is little to spare can flatten the lower face. Dr. Jonghwan Choi, a board-certified plastic surgeon, checks how much fat is actually present before recommending FX, and may suggest Forma alone for a lean face.

Scientific evidence

Studies relevant to FX and Forma: heating fat and dermis

One paper tests selective heating of fat cells with a radiofrequency device, one records collagen and elastin changes after bipolar radiofrequency, one reviews radiofrequency for skin laxity, and one examines how injuries arise in energy-device practice. None studies the handpieces or the patients at Rewind.
