Square Jaw Botox

Square jaw Botox 50U that reduces an enlarged masseter for a slimmer jawline

Procedure Description

Square jaw Botox involves injecting botulinum toxin into the masseter, the muscle used for chewing, to reduce its activity so that its bulk gradually decreases over time. It suits those whose jaw looks angular because of a well-developed muscle rather than bone, and many people with clenching or teeth-grinding habits also choose it. At Sia Clinic Daejeon, square jaw Botox is based on a 50U dose, with products available in Korean-made, Coretox, The Toxin, Xeomin or Allergan. We palpate the muscle to check thickness and left-right differences before planning injection position and depth, aiming to reduce the risk of side effects such as a hollow look when smiling.

Precautions

For 4–6 hours afterward, avoid lying down and do not rub or press the area.

Avoid saunas, alcohol and strenuous exercise on the day of treatment.

Tell us in advance if you are pregnant or breastfeeding, have a neuromuscular condition or take any medication.

For 2–4 weeks, cutting down on tough or hard foods and gum may help; chewing may temporarily feel weaker.

FAQ

When will I see results?

Muscle strength starts to decrease after 1–2 weeks, while the change in bulk usually appears gradually from 2–4 weeks and is easiest to see around 1–2 months. The degree and duration of results vary by individual.

Is 50U enough?

50U falls within the commonly used dose range for both masseters. However, very thick muscles or marked asymmetry may require a different amount, so we advise you after palpation.

Does it work if my jaw is angular because of bone?

Square jaw Botox reduces muscle bulk, so it does not change the shape of the jawbone itself. We assess whether muscle or bone plays the larger role and explain realistically what change to expect.

How do I choose a product?

You can choose Korean-made, Coretox, The Toxin, Xeomin or Allergan. Coretox and Xeomin have reduced or no complexing proteins, which some people consider when concerned about resistance with repeated treatment. Share your history and goals at consultation and we will suggest a suitable product. Results and duration vary by individual.
