InMode FX vs. Forma: What's the Difference? Key Factors for Fat Reduction and Skin Tightening

The biggest difference between InMode FX and Forma lies in "what they target." FX refines facial contours by melting subcutaneous fat layers, while Forma delivers heat to the dermal layer to boost skin elasticity. It is easiest to understand it as one reducing fat and the other tightening texture.

However, there is a common misconception. FX and Forma are not two different 'machines.' Both are simply different modes that use different handpieces (applicators) attached to the main 'InMode' body, a radiofrequency (RF)-based multi-platform developed by InMode in Israel. Therefore, deciding "Should I get FX or Forma?" is not a matter of "Should I go to a different clinic?" but rather "Which tip should I use on the same device?"

🔍 InMode FX and Forma: Are they really the same machine?

Yes, they are. InMode is structured as a platform where multiple handpieces can be swapped onto a single main unit. Handpieces like FX (specifically MiniFX) used for the face, Forma for elasticity, and BodyFX for the body are all part of the same family.

What is commonly referred to as 'InMode FX' in Korea indicates MiniFX, the facial version of BodyFX. On the other hand, 'Forma' is a handpiece that gently delivers bipolar and multi-polar RF energy to the skin surface.

To summarize:

• FX (MiniFX): High-frequency RF + Vacuum suction + High Voltage Pulse (HVP, approx. 2,000V) → Targets the fat layer

• Forma: Uses RF only, controls heat via real-time temperature sensors (A.C.E. technology) → Targets the dermal layer

📌 Key Summary: FX and Forma are not separate machines, but different handpieces attached to the same InMode main unit.

⚙️ FX vs. Forma: How do their working principles differ?

FX focuses on 'reducing fat'

The core of FX is a combination of three technologies. It accesses deep layers by drawing up skin and fat through vacuum suction, applies heat via RF, and simultaneously creates electroporation in fat cell membranes using High Voltage Pulses (HVP). Fat cells damaged in this manner naturally undergo apoptosis (programmed cell death).

Destroyed fat cells do not disappear immediately. They are gradually excreted from the body over about 2 to 4 weeks. This is why the results of FX are often felt several weeks later rather than immediately after the procedure. The treatment temperature for FX is about 45–47°C, which is higher than that of Forma.

Forma focuses on 'boosting elasticity'

Forma involves neither suction nor electrical pulses. It uses solely RF heat to stimulate collagen and elastin in the dermal layer to induce regeneration (collagen remodeling). Temperature control is crucial here.

Forma's A.C.E. technology measures temperature 1,000 times per second and uniformly maintains the skin's target temperature at about 40–43°C. The temperature at which collagen immediately denatures is known to be around 60–65°C, but RF lifting takes the approach of 'gradually' prompting the body to produce its own collagen by steadily sustaining a lower temperature.

📌 Key Summary: FX induces apoptosis in fat cells using suction + electrical pulses, while Forma stimulates neocollagenesis by sustaining gentle heat.

📊 FX vs. Forma at a Glance

📌 Key Summary: If excess fat is your concern, start with FX; if sagging and skin texture are your concerns, Forma is the starting point.

💬 Pain and downtime: What are they really like?

Forma is often called a 'lunchtime procedure.' It feels like a warm stone being gently rolled over the skin, so many people return to their daily routines immediately afterward. Having virtually no downtime is a major advantage of Forma.

FX is different. Because it pulls deep tissue using vacuum suction, bruising, suction marks, and swelling can occur after the procedure. This is not due to improper treatment, but rather a natural reaction inherent to its mechanism. Bruising can typically last from 3 days to 1 week, and up to 2 weeks in some cases.

Additionally, if you regularly take anticoagulants, aspirin, omega-3, certain herbal medicines, or consume alcohol frequently, bruising may be more pronounced. If you have an important event coming up, it is safer to schedule FX with at least a 2-week window.

📌 Key Summary: Forma has virtually no downtime, while bruising from FX is a natural physiological reaction to the suction mechanism.

⚠️ Why you should be cautious of cheek hollowing with FX

Since FX is a procedure that reduces fat, if someone with naturally little facial fat or pre-existing sunken cheeks receives excessive treatment, it can actually lead to cheek hollowing (sunken cheeks). Once lost, cheek fat is difficult to restore, requiring extra caution.

This is why Onlif Clinic prioritizes the overall balance of the face and 'youthful contours' rather than taking a blind, fat-melting approach. For those without much facial fat, tightening elasticity with Forma or lifting sagging contours with other lifting methods often yields far more natural results than carving away volume with FX.

This assessment varies from person to person. Even with the same 'jawline concern,' the root cause may be fat for one person and skin laxity for another. Identifying the true cause of your concern first is essential to selecting the right treatment.

📌 Key Summary: If you have low facial fat, over-treating with FX carries a risk of cheek hollowing, so an elasticity-focused approach should be considered first.

🤝 Is it better to get FX and Forma together?

Because they target different layers, combining them can create great synergy. Contouring the deep fat layer with FX while enhancing surface dermal elasticity with Forma aims for a simultaneous 'reducing and tightening' effect. A combined procedure generally takes around 30 to 45 minutes.

However, not everyone needs both. If elasticity is your only concern, Forma alone may suffice; conversely, if excess fat is your primary concern, more focus should be placed on FX. The criterion is not 'more,' but 'what fits me.'

📌 Key Summary: Combining FX + Forma addresses contour and elasticity simultaneously, but they should be selectively tailored to your specific concerns.

🆚 How does it differ from Ultherapy, Shurink, and Thermage?

Because these procedures are frequently compared, let's highlight their key differences.

• Ultherapy · Shurink: Based on HIFU (High-Intensity Focused Ultrasound), these target deeper layers, such as the deep SMAS layer of the skin, in focused focal points. They differ from InMode's RF in both energy type and depth of action.

• Thermage: A single-session procedure that delivers monopolar RF at high intensity all at once. InMode takes a different approach by repeating treatments at relatively lower temperatures.

• Fat-Dissolving Injections: They overlap with FX in their goal of reducing double chin fat, but rely on an entirely different injectable method.

There is no single correct answer. Which energy fits your skin depth and individual concerns is what matters most, so consulting a clinic that handles both ultrasound (HIFU) and radiofrequency (RF) will give you a wider range of suitable options.

📌 Key Summary: HIFU addresses deeper layers, while RF addresses the dermal to fat layers. It is important to choose according to the depth of your concern.

📅 Onset, maintenance, and are repeated sessions necessary?

Collagen remodeling takes time. Forma's effects appear gradually over several weeks to months, and fat reduction from FX also becomes noticeable after the cell clearance period (2–4 weeks). Rather than 'dramatic in one session,' it is closer to 'natural through progressive accumulation.'

The same applies to longevity. FX is known to last about 1 year to 1 year and 6 months, while Forma lasts about 6 months to 1 year, so regular maintenance is recommended. Significant weight gain can diminish the effects of FX, making concurrent weight management ideal.

📌 Key Summary: Effects appear gradually, and maintaining them requires repeated sessions alongside weight management.

🚫 Who should avoid this treatment (Contraindications)

While RF treatments have a broad safety margin, there are definite contraindications.

• Individuals with electronic medical implants, such as pacemakers

• Individuals with metallic implants in the body

• Those who are pregnant or may be pregnant

• Individuals prone to keloids or with skin diseases in the treatment area

• Those who have recently undergone other intense procedures, such as ablative lasers or fillers (interval adjustments needed)

After the procedure, adhering to basic post-care—such as sun protection, ample moisturizing, and temporarily avoiding saunas and steam rooms—will aid recovery and optimize results.

📌 Key Summary: Electronic medical implants, metallic implants, and pregnancy are contraindications; sun protection and hydration after treatment are essential.

❓ Frequently Asked Questions (FAQ)

Are FX and Forma different machines?

No. They are different modes that attach distinct handpieces to the same InMode main unit. The difference is that FX targets the fat layer, whereas Forma targets dermal elasticity.

Which is more effective for a double chin, FX or Forma?

If fat is the primary culprit, such as with a double chin or buccal fat, FX is more direct. However, if sagging skin is the greater issue, tightening elasticity must also be considered, making an accurate diagnosis of the underlying cause essential first.

Is Forma truly painless?

Many feel only a comfortable thermal warmth, which is why it is called a 'lunchtime procedure.' However, individual pain thresholds vary, so it cannot be guaranteed as completely painless for everyone.

Why does bruising occur after an FX treatment?

It is a natural response inherent to the mechanism of pulling deep tissue via vacuum suction. Bruising typically lasts from 3 days to 1 week, and up to 2 weeks in some cases.

Can I get FX if I have very little facial fat?

Caution is required. Undergoing aggressive FX treatment with low facial fat carries a risk of cheek hollowing, so exploring an elasticity-focused approach first is safer.

How many sessions are needed to see results?

Generally, 3 or more sessions at 2–4 week intervals are recommended for FX, and 5 or more sessions at 1–2 week intervals for Forma. This may vary depending on individual skin condition.

Can I get it right before an important event?

Forma has virtually no downtime, making scheduling flexible; however, FX can leave bruises, so it is best to allow at least 2 weeks of recovery before any major event.

InMode FX vs. Forma: What to check before choosing a clinic

Even for the same procedure, outcomes and recovery processes differ depending on where, by whom, and how it is performed. Asking the following questions during your consultation will help you make an informed decision.

• Does the clinic perform this procedure frequently? — Every clinic specializes in different treatments. Check whether they regularly perform both InMode FX and Forma treatments.

• Can you verify the products and equipment used? — Ask if you can verify product names and authenticity (whether they are officially approved imports, and if there is an unboxing verification procedure) during the consultation.

• Do they clearly explain the cost breakdown? — Rather than just hearing a total price, you need an explanation of what product is being used, how much, and across what areas to make an informed choice.

• Do they design the treatment around the entire face? — Even with the identical procedure, application sites and energy delivery must adjust depending on facial shape, skin condition, and asymmetry.

• Do they explain adverse reactions and recovery beforehand? — Rather than a consultation that only highlights expected improvements, a clinic that thoroughly explains potential side effects and management steps is far more trustworthy.

• Is there a clear follow-up care process? — Check whether there are scheduled check-ins, a way to reach the clinic if complications arise, and established criteria for follow-up visits.
