InMode FX is a radiofrequency (RF)-based medical device referring to a handpiece that targets the fat layer and contours of the face or body. In domestic dermatology clinics, 'InMode FX' often refers to the MiniFX treatment aimed at small areas of the face, such as a double chin, jawline, and deep cheek fat.
The working principle can be summarized in one line. It is a non-surgical method that pulls up the skin using negative pressure, warms the fat layer with radiofrequency heat, and induces collagen regeneration. This is a completely different approach from liposuction, which directly suctions out fat, so it is important to understand the expectations and limitations in advance.
🔍 What exactly is InMode FX?
InMode is a multifunctional platform where multiple handpieces can be plugged into a single device. Therefore, even with the same 'InMode', the purpose of the treatment changes entirely depending on which handpiece is used. The most representative ones are InMode FX and Forma modes.
MiniFX: A small handpiece exclusively for small facial fat areas (double chin, jawline, deep cheek fat).
Body FX: A body-exclusive handpiece targeting body contours such as the abdomen and thighs.
Forma: A handpiece focusing on elasticity and skin texture improvement rather than fat.
📌 Key Summary: InMode FX is a handpiece targeting fat and contouring, and in Korea, it mainly refers to MiniFX for the face.
⚙️ How does it work?
The core of InMode FX is the combination of three elements.
Radiofrequency (RF): It heats the dermis and fat layer to induce collagen remodeling and provide heat stimulation to fat cells.
Negative Pressure/Vacuum Suction (Vacuum): It gently pulls up the skin to help the RF energy reach the fat layer precisely. This is also the main reason bruises occur after the procedure.
High Voltage Pulse (HVP): It is explained as a method that instantly releases a 2,000V pulse to damage fat cell membranes and induce apoptosis.
The temperature favorable for fat cell destruction is known to be 45-47°C, and it is introduced that a temperature sensor detects the temperature in real-time to prevent epidermal burns. Destroyed fat cells are naturally expected to be slowly discharged through natural metabolism like sweat and urine over 2 to 4 weeks after the procedure. Therefore, the effect does not appear overnight.
📌 Key Summary: The principle is to reduce fat and stimulate collagen with a combination of RF heating + negative pressure suction + high voltage pulse.
💫 When and how much do the effects appear?
InMode FX is not a one-time treatment. It is usually conducted with 3 to 6 sessions at intervals of 1 to 2 weeks. The duration of 1 treatment session is about 10 minutes targeted for small facial areas.
Feeling the effect is linked to the speed of collagen regeneration. Usually, changes begin to be felt 2 to 4 weeks after the treatment, and become most distinct around 1 to 3 months. The maintenance period varies greatly by individual and needs management according to aging or weight change.
To address one misconception, it is not true that a severe bruise means a greater effect, nor does no bruise mean no effect. Bruising is just a side effect that occurs during the negative pressure suction process.
📌 Key Summary: 3 to 6 repetitions are basic, the effect starts appearing after 2 to 4 weeks and is most distinct at 1 to 3 months, and the presence of bruising does not prove the effectiveness.
🆚 How is it different from Forma, HIFU, Thermage, and liposuction?
Energy treatments can be confusing because their names are similar. It is easy to organize them by dividing by purpose and depth of action.
Classification | Method | Main Target | Main Purpose |
|---|---|---|---|
InMode FX | Radiofrequency (RF) + Negative Pressure + HVP | Fat Layer/Contour | Fat reduction, jawline tightening |
InMode Forma | Radiofrequency (RF), maintaining 40-43℃ | Dermis Layer | Improvement of elasticity and skin texture |
HIFU (Ultrasound Lifting) | Focused Ultrasound | SMAS Fascia Layer | Deep layer lifting |
Thermage Family | Monopolar RF | Dermis | Skin tightening |
Liposuction | Surgical Removal | Fat Layer | Direct removal of fat |
In particular, InMode FX and Forma are closer to sharing roles rather than competing. FX has strengths in fat and contouring, while Forma is strong in elasticity and skin texture, so they are often done together. If you have relatively lots of fat, you focus on FX, and if you have thin skin and are worried about fine wrinkles, you focus on Forma.
On the other hand, liposuction is a surgery that directly removes fat, so when the amount of fat itself is large, there is a limit with non-surgical treatments alone. Onlif deals with non-surgical treatments from a dermatological perspective, so in this case, rather than forcing a promise of results, prioritizing checking the individual's condition comes first.
📌 Key Summary: The purposes are different, with FX for fat/contour, Forma for elasticity, and HIFU for deep fascia layer lifting, and if there is a large amount of fat, the limits of non-surgical treatments must be acknowledged.
⚠️ Who is it suitable for, and who should be cautious?
InMode FX is relatively suitable for a double chin/jawline where some fat and sagging exist together. On the contrary, it is not an unconditionally good treatment.
Cases where suitability may be low
Slim skin type with originally little facial fat → Excessive treatment can cause cheek hollows/sunkenness, making you look older instead.
Cases with severe sagging or large amount of fat → Limit of non-surgical treatment alone.
Main Contraindications
Pregnant or breastfeeding
People with pacemakers/electronic devices implanted in the body, or metal implants in the procedure area
People with active dermatitis/infection, those taking anticoagulants, or those with a keloid constitution
Above all, the variation in effects and side effects is large depending on the practitioner's skill. Therefore, Onlif aims for a method where specialized doctors only take charge of the treatments they do best. Nobody can be good at everything.
📌 Key Summary: It fits well with jawlines that have both fat and sagging, but for thin faces, there is a risk of cheek hollows, so determining the condition is key.
🏥 Reasons and Checkpoint for Different Programs by Hospital
As mentioned earlier, the handpiece referred to as 'InMode FX' may differ by hospital. Some places call only MiniFX as such, while others offer a package combined with Forma.
Therefore, it is good to check this during consulting:
Which handpiece is used to target which area of the face in the program
Whether it is FX alone, or in combination with Forma, etc.
As InMode is a device approved by US FDA and Korean MFDS, authenticity
Do not assume it is the same treatment just by looking at the name 'InMode FX'. The habit of checking the contents of the package reduces disappointment.
📌 Key Summary: Since InMode FX is a broad expression and the program contents differ by hospital, make sure to check the handpiece, area, combined use, and authenticity.
🙋 Frequently Asked Questions (FAQ)
What is the difference between InMode FX and Forma? Do I need to get them together?
FX has strengths in fat and contouring, and Forma has strengths in elasticity and skin texture. The two are not in competition but rather share roles, so they are often performed in combination when fears of both fat and elasticity exist. However, the necessity depends on individual conditions.
Does the treatment hurt? Is anesthesia required?
There is discomfort due to negative pressure and heat, but anesthesia is usually not required for small facial areas. Pain sensitivity varies individually, so it is good to let them know in advance during the consultation.
If I don't get bruised, does that mean there is no effect?
No. Bruising is just a side effect that occurs during the negative pressure suction process, and does not directly prove the effectiveness. Even without bruising, collagen regeneration and fat reduction can occur.
How many sessions do I need to receive, and how long does the effect last?
Usually, 3 to 6 sessions are conducted at 1 to 2-week intervals. The effect begins to show 2 to 4 weeks after, is most visible in 1 to 3 months, and the maintenance period varies greatly by individual and needs management.
My face is on the thin side, can I still receive it?
Caution is required. If performed excessively on a face with little fat, it can give an older impression due to cheek hollows/sunkenness, so the amount of fat and degree of sagging must be examined together before the treatment.
Is it possible even after receiving fillers or thread lifting?
It is often possible, but adjustments of the interval are needed depending on the type, area, and elapsed time of the previous treatment. Make sure to report your treatment history and decide after a consultation.
Can I go on with my daily life on the day of the treatment?
Since it is a non-invasive method, makeup or going to work is generally possible from the day of. However, bruising, swelling, and heat sensation may remain for a few days, and it is better to postpone saunas, drinking, and strenuous exercise for a few days.
InMode FX can be a good choice for someone it fits well, but it is not the correct answer for everyone. The approach changes entirely depending on whether it is fat or sagging, and how much fat there is. An accurate decision requires a consultation with medical staff who directly inspects your face. Onlif Clinic Gangnam prioritizes natural removal of the concerns that block your inherent beauty, rather than altering your shape.
