After receiving an InMode consultation, many people first wonder, "Will my jawline be defined right after just one session, or does it take multiple sessions?" It can be especially confusing to tell whether a double chin feels like it is losing fat or gaining elasticity.

To give you a quick answer, InMode typically works through multiple spaced-out sessions, gradually slimming down the jawline and double chin over time. You might feel a slight firmness after the first session, but as sessions build up, the contour becomes noticeably clearer. It is more accurate to view it as a "cumulative" progress rather than a "one-shot miracle." Since it targets both the fat layer and skin elasticity, the change happens step-by-step rather than all at once.

Even for the same jawline area, each person's fat volume and degree of sagging are different, meaning the required sessions and the moment you notice a difference will vary. In this guide, we will break down how InMode reshapes the jawline and double chin over multiple sessions, and help you gauge how many sessions you might need based on your concerns.

In this post, you'll learn

• How InMode works on the jawline and double chin

• How results build up over multiple sessions

• How many sessions you should plan for as a baseline

• What to keep in mind regarding session intervals and aftercare

For those new to InMode and the concept of multiple sessions

InMode is a treatment that uses radiofrequency energy combined with vacuum suction to target both the subcutaneous fat layer and the dermis simultaneously. The radiofrequency heat stimulates collagen to firm up the skin, while simultaneously delivering thermal energy to the fat layer to help reduce under-chin volume. Because these two actions accumulate gradually over sessions rather than showing a massive change all at once, it is helpful to understand the concept of multiple treatments from the start.

Radiofrequency (RF)*: An electrical current energy that creates heat inside the skin to stimulate collagen regeneration. This is the mechanism by which InMode treats skin elasticity.

Dermis*: The layer beneath the epidermis where collagen and elastic fibers are concentrated. This is the reason why the elasticity restoration response occurs within this layer.

Clinical reports showing that RF-based devices induce both dermal collagen remodeling and subcutaneous fat layer changes to improve contour and elasticity explain why changes appear gradually in line with tissue healing, rather than finishing all at once. Therefore, it is too early to judge the outcome based on the first session alone.

How do the jawline and double chin change session by session?

Since InMode is a treatment where results build up over time, the expected changes differ slightly by session. Broken down step-by-step, it generally looks like this:

As you can see from the table, InMode benefits become much more noticeable starting around the middle of the treatment process. However, because everyone's fat volume, loose skin, and skin thickness differ, individual experiences can vary even with the same number of sessions. This is why it is often better to adjust your plan as you observe your progress rather than fixing an exact number of sessions from the start.

Who is InMode best suited for?

InMode is ideal for those who want to slim down their jawline and double chin step-by-step without resorting to surgery. It is especially worth considering if you are concerned about both slightly sagging lines and a loss of skin elasticity.

• Those concerned about a fading, soft jawline — Great for addressing both elasticity and definition

• Those with a double chin accompanied by loose skin — Targets both the fat layer and the skin

• Those who want to avoid the burden of surgery — Approaches improvement gradually over spaced-out sessions

• Those who can commit to consistent care — Its cumulative nature pairs well with a structured treatment plan

However, if you have a significant amount of localized fat or advanced sagging, combining InMode with other procedures may be more realistic than doing it alone. Since the required sessions and custom plan vary based on your unique skin condition, it is always best to discuss this during a face-to-face consultation rather than deciding on your own.

Why Hapjeong Beauty stone?

Instead of pressuring you into unnecessary extra sessions, we aim to guide you through just what is necessary for your goals.

What to expect during the InMode procedure

The InMode process begins with a careful consultation to assess the condition of your jawline and double chin. The procedure then applies radiofrequency energy and suction tailored to those areas. A single session usually does not take very long.

• Consultation & Assessment — We first evaluate the fat volume and level of skin laxity

• Custom Session Plan — We determine the number of sessions and intervals to match your goals

• RF & Suction Treatment — Energy is delivered safely to the jawline and under-chin area

• Wrap-up & Aftercare Guide — We check for immediate skin reactions and guide you on your next session date

After the treatment, you may experience mild redness or a slight dull ache for a day or two, but this typically resolves naturally. To allow the changes to stabilize beautifully, it is helpful to stick to the recommended session intervals and maintain basic care like wearing sunscreen and moisturizing. Since this guide contains general educational information, it is safest to consult with a medical professional to determine your suitability and plan your personalized session schedule.

Frequently Asked Questions

Q. How many InMode sessions do I need?

A. It varies by individual, but results typically accumulate over multiple spaced-out sessions. Because the first session offers mild firming, while more defined contouring starts around the midway mark, it is best to plan as part of a series rather than expecting a single session to do it all. The precise number of sessions is safest to decide with a medical professional after analyzing your fat volume and skin elasticity.

Q. Does it reduce double chin fat, or does it tighten skin elasticity?

A. It does both. The radiofrequency heat tightens skin elasticity while also targeting the underlying fat layer to improve under-chin volume. Because of this dual action, many clients feel that their overall jawline becomes much cleaner and more defined, rather than simply losing fat.

Q. If I don't see changes after the first session, does that mean it's not working for me?

A. Not at all. Since InMode results compile over time, it is normal not to see dramatic changes after just one session. The benefits tend to become much clearer as you progress through the middle sessions, so it is too early to judge the overall results on the first treatment alone.

Q. What is the recommended interval between sessions?

A. In most cases, sessions are spaced a few weeks apart. If sessions are too close together, it can put undue stress on your skin's healing process, whereas placing them too far apart makes it harder to build up the cumulative effect. It is ideal to set the timing with your practitioner by checking how your skin recovers.
