Masseter Botox for Jaw Slimming

Masseter Botox relaxes the large chewing muscles at the angle of the jaw. As the muscle is used less it shrinks over several weeks, narrowing a square lower face and easing teeth grinding and jaw clenching.

It is one of the most effective non-surgical ways to change face shape, provided the width comes from muscle. It does nothing for a wide jawbone or for fat.

What Masseter Botox for Jaw Slimming involves

You clench your teeth so the doctor can feel and mark the bulk of the muscle. Botulinum toxin is injected at three to five points on each side, deep and within a safe zone in the lower back part of the muscle, away from the muscles that move the smile.

Who is a good candidate for Masseter Botox for Jaw Slimming?

A simple test: if the angle of your jaw bulges firmly when you clench, muscle is contributing.

• A square or wide lower face caused by enlarged masseter muscles
• Teeth grinding, clenching, morning jaw ache or tension headaches
• Wants a slimmer, more oval face without surgery
• Firm skin that will retract as the muscle reduces

It is usually not the right choice if:

• Width caused by the jawbone, which needs surgical contouring
• Lax skin or early jowls, which can look worse when the supporting muscle shrinks
• Pregnancy, breastfeeding or a neuromuscular disorder
• Professional reliance on strong chewing or certain wind instruments

Technique options

• Standard dosing: typically 20 to 30 units of Botox per side, more for very strong muscles
• Staged first year: two or three sessions to bring the muscle down, then maintenance
• With chin or jawline filler: to refine the contour once the width has reduced

What happens during your treatment

The injections take 10 to 15 minutes and need no numbing. There is no visible change on the day.

Preparing for your trip

One visit is enough, but the slimming appears after you are home and the treatment needs repeating, so it suits people who travel to Türkiye regularly or can continue with a doctor at home.

• Tell the doctor about medication, allergies, pregnancy or breastfeeding, and any history of cold sores, keloid scars or autoimmune disease
• Avoid alcohol, aspirin and anti-inflammatory painkillers for a few days beforehand if your own doctor agrees, to reduce bruising
• Arrive without make-up on the treatment area and avoid sunbeds and strong sun for two weeks before

Recovery and results

No downtime. Chewing tough food may feel tiring for the first weeks. Clenching eases within one to two weeks; visible slimming takes four to eight weeks.

• Back to everyday activity: None
• When results show: 4 to 8 weeks for slimming
• How long they last: 4 to 6 months, longer with repetition

Safety, risks and revision policy

Side effects are temporary because the medicine wears off:

• An uneven or restricted smile if the toxin reaches neighbouring muscles
• Chewing fatigue
• Bulging of part of the muscle when clenching, usually corrected with a small top-up
• A hollow look under the cheekbone or more noticeable jowls in people with lax skin
• Bruising or headache

Every written proposal arranged through Clinic-Y states what the clinic covers if a correction is needed. Ask for it before you book, not after.
