Jaw Hyaluronic Acid Frequently Asked Questions

A chin hyaluronic acid treatment is a procedure in which hyaluronic acid is injected into the chin to refine the shape of the chin and the jawline.

It is used to address concerns such as a small jaw, a jaw that appears receded, a desire to refine the jawline, or a desire to improve the E-line of the profile.

Hyaluronic acid injections into the chin are used to create a design that emphasizes the "E-line" of the profile by adjusting the relationship between the nose and the chin. However, the most suitable method varies depending on factors such as bone structure and the shape of the nose.

The amount of hyaluronic acid injected into the chin varies depending on the patient’s bone structure and desired results; at YAYOI CLINIC, we generally recommend approximately 1 to 3 cc. The required amount is not fixed; it is determined after assessing not only the shape of the chin but also the overall balance of the face.

When receiving hyaluronic acid injections in the jaw area, you may feel a slight prick or a sensation of pressure. At YAYOI CLINIC, we use devices such as a "vibrating pen" for patients who request it, taking care to minimize discomfort during the procedure. We also offer local anesthesia as needed.

Hyaluronic acid injections in the jaw may cause swelling, redness, bruising, pain, and other side effects. The severity of these symptoms varies from person to person.

This treatment is ideal for those who wish to refine the shape of their jawline or change the appearance of their profile. It is particularly popular among individuals with a small or receding jaw, those seeking to improve their E-line, and those looking to adjust the overall balance of their face. At YAYOI CLINIC, we assess the balance of the entire face—including not only the jaw but also the nose and mouth—and propose injection volumes and designs tailored to each individual.

Hyaluronic acid injections for the jaw are a procedure that adds volume to refine the shape and contour of the jaw, while Botox for the jaw is a procedure that targets the movement of the jaw muscles. Therefore, the appropriate treatment depends on whether you want to refine the shape of your jaw or address concerns caused by muscle movement. Depending on the condition of your bone structure and muscles, we may recommend a combination of both treatments.

After the procedure, it is important to avoid applying strong pressure, massage, or friction to your jaw. You may wash your face and take a shower on the same day, but please refrain from taking long baths or engaging in strenuous exercise.

As long as there are no issues with the treated area, you may apply makeup after receiving hyaluronic acid injections.
