Have you heard of jaw Botox? Concerns such as “My face looks a little big” or “I’m self-conscious about my jawline in photos” may actually be caused by a “square jaw” resulting from the development of the masseter muscle—the muscle used for chewing.
This article is intended for those who are concerned about their prominent jawline and are considering cosmetic procedures in Bangkok, Thailand. For those who have almost given up, thinking, “I can’t change my facial bone structure…,” we’ll explain how jawline Botox works and cover some key points to keep in mind.
What results can I expect from jaw Botox?

First, let’s take a look at the basics and how jaw Botox works.
What is a jawline Botox treatment?
Jaw Botox is a procedure involving the injection of a type A botulinum toxin preparation (commonly referred to as “Botox”) into the masseter muscle, which is located in the jaw area. The masseter muscle is involved in actions such as clenching and grinding the teeth.
Botox injections into the jawline help relax the masseter muscle, reducing the prominence of the jaw and creating a sleeker-looking jawline. Since this procedure does not involve any incisions, it is convenient and places minimal strain on the body.
How Botox Injections into the Jaws Affect the Jawline
The masseter muscle is the muscle on the side of the cheek that is used when chewing. When it is constantly used intensely, it becomes more developed, making the face appear wider and causing the jawline to stand out. Injecting Botox into this muscle weakens its contraction, thereby reducing the prominence of the jawline.
What results can I expect from Botox injections?
The main benefits you can expect from jaw Botox are as follows.
- A Slimming Effect on the Face Through Reduction of the Masseter Muscle
- Reducing clenching and teeth grinding
- It makes your jawline look soft and beautiful
However, since the muscle itself is not removed, the results are not permanent. Regular maintenance is required.

Everything You Need to Know About Botox Injections for the Jawline

Some people are interested in jaw Botox injections but are hesitating because they have “some concerns.” For those individuals, we’ve compiled a list of frequently asked questions.
What do the changes look like after the injection?
After the first session, most people notice a change subtle enough that they simply think to themselves, “I wonder if my facial contours have become a little softer than before.” By the second or third session and beyond, some people start hearing comments from those around them, such as, “Your face looks smaller.”
For people who clench their teeth, this may be accompanied by changes such as “my jaw doesn’t get as tired at night” or “the sound of my teeth grinding has decreased.”
When do the changes start to appear, and how long do they last?
If you’re going to get jawline Botox, you naturally want to see results as soon as possible. Some of you may be wondering, “When will I start to notice the effects?”
Generally speaking, it is said that you will begin to notice changes around two weeks after the injection, with the effects peaking around that time. Some people may notice changes as early as two to three days after the injection.
The effects typically last about 3 to 6 months. The duration varies depending on the development of the masseter muscle, daily habits, and the type of formulation used. With regular maintenance, muscle growth may slow down, and in some cases, the duration of the effects may gradually increase.
What are the side effects and risks to watch out for?
The main side effects and risks associated with jaw Botox include swelling, redness, and bruising at the injection site, but these symptoms usually subside within a few days.
In addition, you may find it difficult to chew hard foods or clench your teeth. Most people usually get used to it within a few days to a week.
In addition, in rare cases, if the treatment is too strong or too much fat is injected, it may cause discomfort when smiling or eating. Depending on the amount of fat and the degree of skin laxity, a reduction in muscle mass may cause the cheeks to become sunken or saggy.
This is especially important for people whose skin has lost elasticity due to aging. If you’re worried that “jawline Botox injections might make me look older,” please consult your doctor.
