How Does Jawline Contouring Change with Square Jaw Botox? image 1

Hello, this is Woori Plastic Surgery.

Many people consider square jaw Botox because their jawline looks angular or the lower part of their face appears wider. It is known as a relatively low-burden procedure, but rather than approaching it with the simple expectation that it will just make the jaw smaller, it is important to understand how it works and who it is suitable for.

Today, we will organize how the effects of square jaw Botox appear, how long they last, and which cases it is suitable for.

How Square Jaw Botox Works

Square jaw Botox is not a procedure that reduces the jawbone; it works by easing the movement of enlarged masseter muscles.

As muscle use decreases, the muscle gradually becomes smaller over time, and as a result, the angular jawline can become more softly defined.

Therefore, it can be considered more suitable when muscle development, rather than bone structure, is the main cause.

When Will the Change Be Noticeable?

Square jaw Botox does not produce an immediate change right after the procedure.

Usually, the jawline becomes more refined gradually over 2 to 4 weeks, and at first, many people notice that the firmness felt when clenching the jaw is relieved.

After that, as time passes, the lower face can appear more naturally balanced.

How Long Does It Last?

Square jaw Botox is a procedure whose effects are maintained for a certain period.

Although it varies from person to person, it generally lasts about 4 to 6 months, and muscle function gradually recovers over time.

If you want to maintain a continuous jawline, getting the procedure at regular intervals may be helpful, and repeated treatments may also positively help reduce excessive muscle development.

Is It Applicable to All Square Jaws?

The causes of a square jaw are not all the same.

If the cause is muscle development, Botox can be expected to bring changes, but if the bone structure itself is developed, there may be limits to what Botox alone can achieve.

Therefore, before the procedure, it is important to accurately distinguish whether it is due to muscle type or skeletal type, and an approach suited to the cause can affect satisfaction.

Square jaw Botox is a procedure that softens the developed jaw muscles and makes the facial line look smoother.

The effects appear gradually, and the duration can also vary depending on an individual's muscle-use habits and management methods.

Rather than deciding based only on trends or reviews, it is important to first accurately identify the current jaw structure and cause, then plan the direction that is right for you.
