Frequently Asked Questions About Facial Slimming and Contouring

There are various reasons why a face may appear larger, including puffiness, fat, the muscles and bone structure of the jawline, and sagging skin. In some cases, puffiness may be temporary due to excessive salt intake, while in others, fat or sagging under the chin may cause the facial contours to appear blurred. At YAYOI CLINIC, we’ll discuss the areas of concern with you and explore treatment options tailored to the underlying cause.

At YAYOI CLINIC, we select treatment methods based on the causes of your facial contour concerns—such as prominent jawlines or sagging skin—and your desired results. Options include treatments such as Thermagen and Super HIFU, as well as injections of botulinum toxin and hyaluronic acid. We also assess your facial features and skin condition to provide personalized recommendations tailored to each individual.

If your prominent jawline is caused by the development of the muscles used for chewing, Botox injections for the jawline may be an option. At YAYOI CLINIC, we offer Botox injections as a treatment to reduce the activity of the masseter muscle and refine the jawline. However, since a prominent jawline can also be caused by other factors, such as bone structure, we recommend determining the cause through a consultation before considering this treatment.

If your double chin is noticeable due to sagging skin, you may want to consider treatment with medical-grade HIFU. YAYOI CLINIC’s Super HIFU offers treatments for the entire face and under the chin, delivering heat deep into the skin to promote tightening. Since fat and bone structure also play a role in the appearance of a double chin, it is important to determine the underlying cause through a medical examination.

A treatment combining HIFU and Thermagen is also an option. At YAYOI CLINIC, we have treated patients using a combination of Super HIFU and Thermagen. Since the mechanisms of the treatments and the layers they target differ, we will assess your facial sagging and skin condition to determine whether this combination is appropriate for you.

With facial slimming and contouring treatments, you may experience some discomfort during injections or when the device is applied. While YAYOI CLINIC’s Super HIFU is designed with patient comfort in mind, you may still feel some discomfort during treatment. Since pain tolerance varies from person to person, please let us know during your consultation if you have any concerns.

After facial slimming treatments, swelling or bruising may occur depending on the method used. For example, jawline Botox carries risks such as pain, swelling, and bruising at the injection site, while Super HIFU carries risks such as redness and puffiness. Since recovery varies from person to person, if you have plans, be sure to review the precautions before your procedure.

The number of sessions required for facial slimming treatments and the interval between visits vary depending on the type of treatment and the condition of your face. At YAYOI CLINIC, we recommend a follow-up treatment with Super HIFU after 6 months to maintain its effects. For jawline Botox, we generally recommend one treatment every 3 to 4 months. We will determine whether follow-up treatments are necessary and when to schedule them during your consultation.

Hyaluronic acid injections into the chin are an option for improving facial contours and the balance of your profile. At YAYOI CLINIC, when performing hyaluronic acid injections into the chin, we assess the harmony not only with the chin but also with the forehead, nose, and mouth area to determine the appropriate injection volume. Even if your chin is small and your facial contours appear blurred, we will determine during your consultation whether this treatment is suitable for you.

There are also treatments available that refine facial contours without removing bone. At YAYOI CLINIC, we offer botulinum toxin injections that target the masseter muscles, as well as Thermagen and HIFU treatments designed to address sagging skin. However, these treatments do not actually reduce the size of the bone structure itself. For more details, please visit our page on facial slimming and contouring procedures.
