Gangnam InMode: What Is the Difference Between FX and Forma? image 1

Hello,

This is Mikay Clinic, where we care about your skin together.

When you tie your hair up on a hot day,

sagging skin under the chin

or a double-chin line can look particularly noticeable.

That is why many people look into InMode

as a non-surgical way to manage skin firmness,

but many are often confused about the difference between FX and Forma.

InMode is a non-surgical lifting device

that stimulates the skin with radiofrequency (RF) energy.

It is divided into the FX mode, mainly used for fat and contour management,

and the Forma mode, used for firmness and tightening,

so the modes can be combined according to your concerns.

If you are looking into Gangnam InMode,

it is best to start by distinguishing the roles of the two modes.

Q1. What is the difference between InMode FX and Forma?

FX focuses on managing fat and contours in deeper layers,

while Forma focuses on firmness and tightening in shallower layers.

Even with the same InMode treatment,

the target layer and purpose differ depending on which mode is used.

Non-surgical tightening based on radiofrequency

has been increasing worldwide,

with approximately 1.24 million non-surgical skin-tightening procedures

performed in 2024, a 38.9% increase over the past four years.

(ISAPS 2024)

Q2. When do the effects begin to appear?

You may feel some tightening immediately after the procedure,

but more significant changes appear gradually over several weeks

as collagen builds up.

It may be helpful to receive multiple treatments rather than just one.

The effects and how long they last

vary considerably from person to person depending on skin condition.

Therefore, it is better to approach the treatment

as consistent care rather than expecting immediate changes.

Q3. Is there pain or downtime?

As radiofrequency thermal energy is delivered,

you may feel warmth or a prickling sensation.

Temporary redness or swelling may occur after the procedure,

and although it usually subsides over time,

reactions vary from person to person.

The intensity is adjusted according to your skin condition.

A setting suited to your skin is more important

than using an excessively high intensity.

Q4. How is it different from Shurink and Ulthera?

InMode uses radiofrequency (RF),

while Shurink and Ulthera use ultrasound (HIFU),

so the energy methods themselves are different.

The depth of action and sensation also differ,

so the more suitable method depends on the area of concern.

It is not a matter of one being better than the other;

the choice depends on the purpose.

Whether Gangnam InMode is right for you

is best determined by examining your skin condition.

It may be considered if you are concerned about

a double chin, lower-cheek fullness, or subtle sagging along the jawline.

Points to know before the procedure

Caution is needed if you have an implant in the treatment area,

are pregnant,

or have an electric device related to the heart in your body.

If you are taking medication or have a skin condition,

it is best to inform the medical staff in advance.

Moisturizing, sun protection, and regular lifestyle habits

also help maintain an environment supportive of collagen.

Continuing basic care even after Gangnam InMode

can help maintain the treated firmness for longer.

In closing

Gangnam InMode: What Is the Difference Between FX and Forma? image 7

InMode is a treatment in which the FX and Forma modes

are combined according to your concerns;

the same approach is not suitable for everyone.

This is because the necessary mode and intensity differ

depending on the area of concern and skin condition.

The most accurate way to determine which mode and intensity suit your concerns

is to have them decided based on a medical professional’s assessment

during a Gangnam InMode consultation.

At this time of year, when the feeling of heat-related laxity is bothersome,

we recommend seeking an accurate diagnosis first

rather than making an overly hasty personal judgment.

※ Treatment effects and reactions may vary from person to person,

and side effects may occur.
