When the area under the jaw looks swollen or the area below the ears feels wider, many people simply think they have gained weight. However, in reality, it may be a change caused not by fat, but by enlarged salivary glands.

In particular, when repeated stimulation occurs depending on eating habits or lifestyle patterns, the area can gradually become more prominent, and the face line may appear less defined.

In this article, we’ll organize everything from the causes of enlarged salivary glands to the principle of Seongnae-dong Botox, one of the methods used to help reduce it, as well as when changes appear and how long the effects last.

Cheonho-dong Botox: Causes of Swollen Salivary Glands,

Why does it happen?

There are various causes of enlarged salivary glands.

✔️ If you have a habit of repeatedly vomiting after overeating

The salivary glands can be continuously stimulated and gradually become hypertrophic.

✔️ When the inside of the mouth remains dry

The area may appear swollen as a compensatory response.

✔️ When overwork and stress accumulate

The area may react sensitively.

✔️ When binge eating is repeated after extreme weight loss

Pressure may be placed on this area, leading to a change that makes the area under the jaw look swollen.

In this way, it can occur for a variety of reasons. This solution works by injecting botulinum toxin into the overly developed area to reduce its size.

When changes appear after care

Hypertrophy can appear in different forms depending on the location. When the area under the jaw becomes larger, it may look like sagging jaw fat, and when the area below the ears widens, the face may look larger or feel more square-shaped.

At this time, if this method is applied, changes tend to appear naturally over time.

In general, many people notice changes after about 2 to 4 weeks, and the volume may gradually decrease.

The duration of the effect is about 4 to 6 months, after which it returns to its original state.

Therefore, if you want continued changes, it may be helpful to receive it repeatedly at 4- to 6-month intervals. However, since the content above may vary depending on the individual’s condition, it should be understood as a general reference.

Precautions after care

Finally, I’ll explain the things you should be careful about after receiving care.

First, after the medication is injected, it is important not to stimulate the area. Avoid rubbing or pressing hard, and it is better to reduce external stimulation.

Also, for about a week, high-temperature environments that raise body temperature can have a negative effect, so it is better to take a break from saunas, bathhouses, and strenuous exercise for a while.

Temporary swelling, redness, or bruising may occur, but these usually improve over time, so there is no need to worry too much.

If you follow the precautions above in your daily life, you may be able to expect better results.

Many people think that enlarged salivary glands are simply due to weight gain. Surprisingly, in many cases, hypertrophy occurs because of lifestyle habits rather than fat.

Therefore, even if you have not gained weight but the areas below the ears or under the jaw look puffy, it may be worth considering this care.

Since this is performed via injection, it is also relatively simple, so please keep that in mind.

Thank you for reading this long post.
