What the chewing muscle has to do with face shape
The chewing muscle (musculus masseter) sits at the side of the lower jaw and helps shape the lower third of the face. If it is very strong or enlarged — for example through chronic clenching and grinding — the lower face can look optically broader and more angular. This is not unhealthy, but some perceive it as too 'square'.
How Botox softens the jawline
If the muscle is relaxed slightly in a targeted way with botulinum toxin, its activity decreases. Since a less-used muscle can lose volume over time, the jaw area often looks slimmer and more defined after a few weeks — subtle and natural, not 'operated on'.
- Short treatment, usually only 10–15 minutes
- The effect develops over weeks, not overnight
- Temporary — a top-up after a few months is common
- No downtime, normal everyday life right afterwards
Those who grind at night anyway often benefit twice: less pressure on teeth and jaw joint — and, as a side effect, a more harmonious jawline. More on this in the article <a href="/en/blog/masseter-botox-gegen-zaehneknirschen">masseter Botox against teeth grinding</a>.
Who is this useful for?
A visible change in shape is only to be expected if the chewing muscle is actually strong or enlarged. That is why, before every treatment, we clarify in a thorough examination whether masseter Botox is suitable for your goal at all — and advise honestly if a different path makes more sense.
