Why it happens
A square lower face is often due to a strong masseter muscle, but bone shape also matters.
What the doctor checks
We check muscle size when clenching and relaxed.
A quick self-check
Clench and relax: if the jaw angle bulges noticeably, muscle is likely a factor.
Treatments that may be considered
- Botox: Botox is a botulinum toxin injection that relaxes specific muscles to soften expression lines or slim areas such as the jaw muscle.

Common questions
What is the best treatment for a square jaw?
If muscle is the main cause, jaw Botox is often discussed. Bone shape cannot be changed without surgery; the doctor checks which applies.
Can it be treated in one visit?
A Botox session takes minutes, and the slimming effect develops over the following weeks.
