Masseter BTX in Singapore

Masseter treatment slims the lower face and relieves clenching — but the muscle behaves differently in year three than in month three.

1. Reduction is gradual and cumulative

Visible slimming appears over four to eight weeks as the muscle atrophies from disuse. With repeated treatment the interval lengthens and the dose required falls, because sustained reduction in bulk persists between sessions.

2. Bruxism relief often arrives before the cosmetic change

Patients who grind report reduced morning jaw tension and headache within one to two weeks — well before any visible narrowing. For many this is the more valuable outcome.

3. Over-reduction has a cost

The masseter contributes to lower-face support. Excessive or overly frequent reduction can produce hollowing at the angle of the jaw and, in some patients, a paradoxical sagging of overlying tissue.

4. Chewing function is preserved at appropriate dosing

Correctly dosed treatment weakens rather than paralyses. Difficulty chewing firm food indicates the dose was too high, not that the treatment is working.
