About facial slimming

We all have areas we want to improve and insecurities we want to change. For many, a wide jawline or lower face area is an area of insecurity. However, achieving a slimmer face can be difficult.

Face slimming is a treatment that visibly narrows the face by injecting the masseter muscles with muscle relaxants. The masseter muscle is a large facial muscle located at behind the jaw that aids us in eating. The treatment works to reduce the contraction of the jaw muscle, preventing it from clenching and bulging, reducing volume in the lower jaw area and creating a narrower shape.

The treatment is not only beneficial for those who want to slim their face, but can also help alleviate certain medical conditions such as bruxism (overactive masseter muscle due to grinding of the teeth) and migraines.

Jawline slimming treatment takes about 30 minutes. After a quick consultation to determine that you are a good candidate, our M1 doctor will inject muscle relaxants into the muscle through the skin. With this, the muscle will no longer contract, preventing the masseter muscle from bulging.

The effects from non-surgical jaw reduction are not immediately visible, as it takes a few days for the muscle relaxants to take effect. The effects typically last between 3 and 4 months after which the relaxant will begin to fade.

Masseter reduction - FAQ & prices

If you are considering this treatment, please read our guidelines for aesthetic treatments.

Face slimming is a treatment that reduces volume in the lower jaw area of the face. Muscle relaxants are injected through the skin into the masseter muscle, which works to stop the contraction of the muscle and visually slimming the face.

Along with visually slimming the face, reducing the masseter can have a number of benefits. It can help reduce the effects of teeth-grinding, bruxism and migraines.

Results are not immediate after jaw slimming. Muscle relaxing injections take a number of days to take full effect. The full effect of reducing the masseter with anti-wrinkle product is visible approx. 10-14 days after treatment.

The durability of a jaw reduction treatment is between three to four months. After this period the injected product begins to fade and the muscle will begin to contract and bulge again. Jawline slimming can be refreshed, in order to maintain the narrowing effect in the long term.

In order for the material to take effect where desired, you should keep your head in an upright position for 4 hours after treatment. We recommend to avoid any sportive activities for 48 hours.
