InMode FX or Forma: Fat First or Skin First?

Last updated: July 2026

If you've been researching InMode, you've probably run into two names that keep popping up side by side: FX and Forma. It's a little confusing, since they're the same brand and the same general technology, yet clinics talk about them like two completely different treatments. Here's the short answer: InMode isn't one single procedure — it's a platform with several handpieces, and FX and Forma are built to work at different depths in the skin. In this article, we'll cover what InMode actually is, how FX and Forma differ, what each mode is generally used for, and how to think about which one might fit what you're dealing with.

What Is InMode, Exactly?

InMode is a radiofrequency (RF) platform, not a single treatment. Think of it as one system with several handpieces built in, each tuned for a different job. Some are designed to work close to the skin's surface. Others are built to reach deeper, toward the connective tissue and fat layer underneath. Forma and FX are two of the most commonly discussed modes, and the reason clinics name them separately is simple: what your skin actually needs determines which one makes sense.

Radiofrequency itself is fairly simple to explain — it's energy that generates heat inside the skin, which in turn encourages the body to produce more collagen. What changes from mode to mode is how deep that heat goes and how it's delivered, and that's exactly where FX and Forma part ways.

What's the Difference Between FX and Forma?

The short answer? Depth. Forma is designed to heat the upper layers of the dermis, closer to the surface. FX is built to reach further down, closer to where the skin meets the fat layer beneath it. Same underlying RF technology, two different targets.

That difference in depth also tends to line up with a difference in purpose. Forma comes up most often in conversations about skin texture, tone, and everyday firmness — the kind of change you'd actually notice by touching your skin. FX comes up more when the concern is facial contour, like a softer jawline or early jowling, rather than surface texture alone.

Neither mode is simply "stronger" than the other — they're built to answer different questions. If rough or crepey-feeling texture is the main complaint, Forma is usually the first thing that comes up. If it's more about contour looking less defined than it used to, FX tends to be the one clinics mention first.

How Does Forma Work?

Forma uses bipolar radiofrequency delivered through a handpiece that's moved continuously over the skin, holding the tissue at a steady target temperature rather than delivering one quick pulse. That steady, controlled warmth is the point — it's designed to reach the upper dermis and stay there long enough to stimulate collagen and elastic fibers without overheating the surface.

Research on a bipolar radiofrequency facial device found that this kind of temperature-controlled RF reaches its target heat within one to two minutes and delivers it evenly, with increases in collagen and elastic fibers observed in the upper dermis afterward. The same research also reported that discomfort tended to be on the milder side compared with some other RF approaches.

In practice, that's why Forma is discussed mostly in terms of skin quality — tone, texture, a slightly firmer feel — rather than a dramatic lift.

How Does FX Work?

FX is built to send energy further down than Forma, closer to the deeper dermis and the fibrous connective tissue that sits near the fat layer. The general idea behind deeper RF delivery like this is that heating that lower connective layer can encourage it to tighten, which is part of why FX gets discussed more in the context of jawline definition and looser-looking contour.

Because it's working at a different depth than Forma, the two modes aren't really in competition — think of them as addressing different layers of the same general concern. Some people end up considering both, spaced out over time, rather than picking strictly one.

What to Expect: Timeline and Results

Neither mode works like a light switch. Right after a session, you might notice some warmth or mild redness, but that's not the collagen effect yet — that part takes time.

• Right after treatment: Skin may feel warm or slightly flushed, calming down within a few hours.
• First couple of weeks: Any tightness you notice this early is mostly residual warmth or mild swelling, not the actual collagen change yet.
• One to three months: This is typically when gradual firming becomes more noticeable, as new collagen continues forming.
• How long it holds: Results vary by person, but effects are commonly described as lasting several months before a touch-up session is considered.

Individual results vary quite a bit — skin thickness, age, and how your body responds to heat all play into it. That's part of why a series of sessions, rather than a single one, tends to come up in these conversations.

Side Effects & Risks

Both Forma and FX are generally considered well tolerated, but it's worth knowing what's typical and what isn't before you go in.

• Redness and warmth: Common right after treatment and usually settles within a few hours to a day.
• Mild swelling: Can show up in the treated area and typically fades within a few days.
• Temporary tenderness: Skin may feel sensitive to the touch for a short stretch afterward.
• Less common: Small blisters, uneven results, or brief numbness have been reported in some cases.

If you notice spreading redness, fever, or pain that keeps getting worse instead of better, seek medical care right away. It's also worth mentioning any skin conditions or medications you're on during your consultation, since that can change what's recommended for you.

How Much Does It Cost?

Pricing for InMode FX and Forma varies by clinic, the area being treated, and how many sessions your provider recommends, so there isn't one number that applies across the board. Rather than guessing at a figure, a consultation is really the best way to find out what a plan built around your skin would run — you can see current offers at /en/promotion.

The Bottom Line

InMode isn't one treatment — it's a platform, and FX and Forma are two of its modes, built to work at different depths. Forma stays closer to the surface, aimed at skin texture and everyday firmness. FX reaches deeper, aimed at contour and looser-looking tissue along the jawline. Like most RF-based treatments, both come with a gradual timeline and mild, temporary side effects rather than an overnight transformation.

• InMode is a platform with multiple modes, not a single treatment.
• Forma targets the upper dermis for texture and firmness; FX reaches deeper for contour.
• Results build gradually over weeks to months, not overnight.
• Side effects are typically mild, but it's worth knowing the red flags.

Ultimately, the choice depends on what you're actually dealing with — surface texture, deeper contour, or a bit of both. If you're trying to figure out whether FX or Forma fits what you're seeing in the mirror, a consultation is the best way to find out.

Frequently Asked Questions

Q1. Can I get FX and Forma on the same day?

Some providers do combine them in the same visit since they target different depths, but it depends on your skin and what your provider recommends. It's worth bringing up during your consultation rather than assuming either way.

Q2. Does InMode hurt?

Most people describe it as warmth or mild tingling rather than sharp pain. Forma tends to feel milder since the heat builds gradually, while FX can feel a bit more intense as it reaches deeper — but discomfort is usually manageable and settles quickly after the session.

Q3. How long do results last?

Results vary quite a bit from person to person, but effects from either mode are commonly described as lasting several months before a touch-up is considered. Skin thickness, age, and lifestyle all play a role.

Q4. How do I know if I need FX or Forma?

It generally comes down to what's bothering you. If it's more about skin texture and everyday firmness, Forma is usually discussed first. If it's more about a softer jawline or loss of contour, FX tends to come up instead — but a consultation is the most reliable way to figure out which one actually fits.
