InMode FX Korea, Lower-Face Contour in Gangnam

InMode FX is a bipolar radiofrequency mode aimed at the fat layer of the lower face. The current runs at 1 MHz between two electrodes on the handpiece, heating the dermis and the subcutaneous fat beneath it, roughly 2 to 6 mm down, while an impedance sensor keeps the tissue at 42-45°C. That controlled heat softens a fat pocket under the chin over the following weeks. At RE:BERRY Gangnam it is usually run with Forma, the tightening mode, so the skin firms as the pocket shrinks. The entry rate and package options are on the ₩190,000 (about $136) pricing section.

FX and Forma are two modes of the same InMode platform, tuned to different jobs. FX concentrates heat to reduce a fat pocket; Forma delivers a steady dermal warmth to stimulate collagen and firm loose skin. On a lower face where a soft double chin sits under slightly lax skin, treating only the fat can leave the surface a touch slack, and treating only the skin ignores the pocket. Running both in one appointment addresses the two at once, and the physician sets how many zones go to each after the pinch test.

It does both, by design, which is the point of pairing FX with Forma. FX heats the subcutaneous fat directly at 2-6 mm, so the treated pocket softens gradually over weeks rather than all at once. The same warmth stimulates the dermis above, so the skin contracts as the fat reduces. If a physician finds the fullness is almost entirely loose skin with little fat, they will lean the plan toward Forma; if it is a firm fat pad, FX carries more of the work.

An impedance sensor built into the platform reads the tissue and adjusts the current every 100 milliseconds, holding the treated area in a 42-45°C window and stopping it from climbing past. Manufacturer registry data on the InMode platform reports a thermal burn rate of 0.09% across 2,150 treatments, and the registry describes it as several times safer than monopolar RF on this measure. At RE:BERRY Gangnam the physician also reads your feedback zone by zone as an added check.

Most lower-face plans run as a short series, often four to six sessions, because fat-layer heating works gradually and stacks over repeat visits. A single visit can still make a visible difference for a small pocket, but a course gives a cleaner, more durable contour. After a completed course, a single maintenance session around 12 to 18 months out sustains most of the gain. Your physician confirms the number after mapping your zones, not before.

Most guests describe a deep, moving warmth, not a sharp pain. The average score reported on the platform sits around a 2 out of 10. There are no injections for the RF passes, the vacuum-free Forma glide feels massage-like, and the impedance sensor trims energy ten times a second so no single spot spikes. The physician can dial the power down at any point; the platform runs from 1 to 50 watts, so there is plenty of room to keep a sensitive zone comfortable.

Downtime is minimal. Faint redness in the treated zones usually clears in under two hours, and because the skin is never broken there is no wound to protect. Guests routinely fly out the same evening or the next morning. Skip strong heat, saunas, very hot showers, for the first day or two and keep up sun protection, and you can otherwise return to normal life, makeup included, right away.

Early firmness tends to show within the first two weeks as the skin begins to contract. The main change builds toward a peak between days 60 and 90, when new type I collagen matures; dermal thickness measured on the platform rises in the range of 18-25% at 90 days. A completed course generally holds 12 to 18 months, and a single maintenance session in that window sustains the majority of the gain.
