Double chin injections: How many sessions before you see a change?

Some people may notice a partial change after just one session, but for a noticeable improvement in the jawline, multiple sessions are generally needed. The amount of fat that the injection ingredient can break down in a single session is limited, so a gradual approach with repeated treatments is recommended to achieve the desired reduction.

In particular, if there is a large amount of fat, the change after one session may feel relatively small. Conversely, if the fat is small in amount and located superficially, a high level of satisfaction may be achieved with fewer sessions. Therefore, the actual number of sessions needed depends on the amount of fat and the condition of the jawline.

Because the broken-down fat goes through a metabolic process, changes are often noticed gradually over several weeks rather than immediately after the procedure. In the early stages after treatment, swelling may actually make the area appear puffier. As the swelling subsides and the fat is cleared, the jawline gradually becomes more defined. You may not notice as much change as expected after the first 1 to 2 sessions.

The degree of change tends to increase as sessions accumulate, so it is more reasonable to compare before and after completing the planned number of sessions rather than making a hasty judgment after just one or two sessions. The speed and degree of noticeable change can vary depending on individual metabolism and fat characteristics.

Swelling may occur in the treated area, which is a natural reaction as the ingredient works. The degree and duration of swelling vary from person to person; it often subsides within a few days, but for some people it may feel like it lasts longer.

Because the area under the chin is a visible part of the face, it is advisable to schedule the procedure with enough time before important events. If swelling or discomfort lasts longer than usual or feels severe, it is recommended to contact the clinic where you received the treatment to have the condition checked, rather than judging it on your own.

After completing the planned sessions, maintaining a stable weight and lifestyle is key to preserving the results for a long time. Even in areas where fat has been cleared, a significant overall weight gain can cause the volume under the chin to increase again, so managing your diet and physical activity is fundamental to maintenance.

If sagging of the jawline is also present, fat reduction alone may not be sufficient, and combining it with a lifting procedure to improve skin elasticity can be helpful. The appropriate combination and maintenance schedule vary depending on an individual's fat and skin elasticity status, so it is recommended to consult with a dermatologist to establish a plan tailored to you.
