InMode FX Double-Chin Effect: Will It Really Change the Jawline?

“Does a double chin only improve if you lose weight?”

“Is there a way to tidy up only the area under the chin?”

It may not have bothered you much before, but at some point, the jawline in photos can start to catch your eye first.

The face may look fine from the front, but from the side, the boundary between the chin and neck can appear blurred, and when you slightly lower your head, the area under the chin may look folded.

A double chin is not simply a problem caused by weight gain.

When submental fat, skin elasticity, and sagging that extends below the jawline overlap, even a small amount of fat under the chin can look much more noticeable.

That is why, when considering InMode FX, it is important to first examine why the double chin has developed.

1. Why Does a Double Chin Develop?

A double chin is more noticeable when fat gathers under the chin and the boundary between the chin and neck becomes blurred as skin elasticity decreases.

It is especially easy for the area under the chin to look heavy when these factors overlap.

• Soft fat that can be pinched under the chin

• A jawline that has descended due to reduced skin elasticity

• A lower face that looks rounded as the mid-cheek area connects to the jawline

• A structure in which the boundary between the chin and neck becomes blurred

The reason a double chin is bothersome is not simply because fat is visible under the chin.

If the jawline does not flow naturally into the neck, the side profile can look less defined, and the entire face may appear larger.

Therefore, managing a double chin should involve not only reducing submental fat but also lightly refining the line below the jawline.

2. What Kind of Lifting Treatment Is InMode FX?

InMode FX is a lifting treatment that delivers radiofrequency energy to the submental fat layer and lower dermal layer after lifting the tissue while the skin is suctioned.

Rather than simply tightening the skin’s surface, it is designed to address both the fat that can be pinched under the chin and the sagging line.

The areas primarily considered with InMode FX include:

• The fat layer that can be pinched under the chin

• The line that looks heavy below the jawline

• The area where the mid-cheek area connects to the jawline

• The lower facial line that looks less defined

• The jawline that has become blurred due to reduced elasticity

For this reason, InMode FX is often considered when looking into double-chin lifting, management of fat under the chin, and refinement of the lower facial line.

3. How Can It Help With a Double Chin?

The key is to reduce the volume under the chin and refine the area so that the boundary between the chin and neck appears more defined.

The expected direction of change is as follows.

• The volume under the chin looks less prominent

• A reduced sense of folding when lowering the head

• A more defined boundary between the chin and neck

• A less rounded and heavy-looking impression in the lower face

A double chin is an area where changes are often felt more clearly from the side than from the front.

Even a slight reduction in the weight under the chin can make the side profile look more defined and make the overall facial impression look less heavy.

4. When Do InMode Effects Become Visible?

The effects of InMode FX should be evaluated over time rather than on the day of treatment.

The progression after treatment can be understood as follows.

• Around 1 week

Swelling, bruising, warmth, and suction marks may be visible.

Cold compresses, sufficient rest, and avoiding saunas, alcohol, and vigorous massage may help reduce downtime.

• Around 2–4 weeks

The area under the chin may look less heavy, and the jawline may feel slightly lighter from the side.

• 1–3 months

As the skin’s elasticity response gradually continues, the jawline may appear more naturally refined.

The effects of InMode do not appear in a single day. Gradual improvement becomes visible as swelling subsides and the elasticity response continues.

5. Why Should You Be Careful About Hollowing in the Cheeks?

Because InMode FX is a mode that also addresses the fat layer, applying it excessively to areas with little facial fat can make cheek hollowing more noticeable.

The center of the cheeks and the area below the cheekbones, in particular, are areas where facial volume is needed.

If treatment is performed by broadly reducing these areas as well, the face may appear sunken.

Therefore, if the goal is to improve a double chin, the FX treatment area should be centered on the area under the chin and the jawline.

The important point is not to simply lower the intensity, but to distinguish between the areas to reduce and the areas to preserve.

Q&A

Q. What is the InMode Forma mode?

Forma is not a mode that suctions the skin and intensely addresses the fat layer like FX.

It is more focused on gently managing the feeling of elasticity, fine lines, and skin texture on the skin’s surface using radiofrequency energy.

If the concern is submental fat and the jawline, as with a double chin, FX is generally considered the primary option. If the skin also appears loose, Forma may be considered as a complementary option.

Q. When is a good time to have the treatment if I have an important event coming up?

Because bruising or suction marks may occur, it is generally better to avoid having the treatment immediately before an important event.

Mild redness or swelling usually subsides within a few days, but if your skin bruises easily, it is advisable to allow about 1–2 weeks.

For an event where the jawline is a particular concern, such as a photo shoot, planning the treatment 2–4 weeks in advance is a more reliable approach.

In Summary

The key to InMode FX is refining the fat gathered under the chin and the blurred jawline as much as needed.

However, if cheek hollowing is a concern, the area under the chin, the mid-cheek area, and the center of the cheeks should not all be treated in the same way.

If you are considering InMode FX for a double chin, rather than looking only at the intensity or number of treatments, it is advisable to check whether the provider considers both the amount of submental fat and facial volume and can adjust the treatment area accordingly.
