Facial slimming is a popular treatment using anti-wrinkle injections to create a slimmer-looking face.

The treatment can contour the jawline and make the face appear slimmer.

The treatment can also reduce jaw clenching which can also enlarge the masseter muscles of your jaw and cause serious dental problems if not treated properly.

Marjan will strategically place the injections in the masseter muscle of your face to force the thicker facial muscles around the jawline to relax and thin out.

It takes 3 days to 2 weeks to fully take effect, and a second treatment is recommended around 3-4 months.

Aftercare:

Some patients may find the treated area tender and experience slight bruising and swelling but that will soon disappear.

We recommend that you avoid lying down for 4 hours and avoid applying makeup to the treated area.

Avoid active face products such as retinol, vitamin C and AHA’s, and avoid strenuous exercise and massages for at least 24 hours.

Facial slimming is a non-surgical treatment that involves the use of anti-wrinkle injections to contour the jawline. The procedure targets the masseter muscles—the large muscles responsible for chewing. By strategically administering the injectable solution, these muscles are encouraged to relax, which gradually reduces their bulk and creates a softer, slimmer appearance to the lower face.

Yes. Beyond the aesthetic benefits of a slimmer jawline, these injections are frequently used to address medical concerns such as bruxism (teeth grinding) and jaw clenching. Relaxing the masseter muscles can alleviate the tension associated with these habits, potentially reducing related issues such as tension headaches and dental wear.

The effects of facial slimming are not immediate. You may begin to notice a softening of the muscle tension within 3 days, but the visible slimming effect of the jawline typically takes between 2 to 4 weeks to become fully apparent. This timeframe allows the masseter muscle to gradually decrease in size following relaxation.

The results generally last for approximately 3 to 4 months. For those looking to maintain a slimmer facial profile, a second treatment is usually recommended around this time. With consistent maintenance, some patients find that the masseter muscle remains relaxed for longer periods between sessions.

To ensure the best outcome, we recommend that you remain upright and avoid lying down for at least 4 hours after treatment. You should also avoid applying makeup, using active skincare products (such as Retinol, Vitamin C, or AHAs), and engaging in strenuous exercise or facial massages for at least 24 hours to prevent the solution from migrating.

While the procedure is minimally invasive, it is a medical treatment and carries potential risks. Common side effects include temporary tenderness, slight bruising, or mild swelling at the injection site. In rare cases, there may be a temporary change in the strength of your bite or a slight asymmetry in your smile. A full clinical consultation is mandatory to discuss your suitability and individual risks.
