Masseter hypertrophy: Overactive or enlarged chewing muscles (often from clenching/grinding).
Genetics & bite dynamics: Natural lower-face width or dental/occlusal factors.
Compensatory muscle use: Stress and habit can maintain muscle bulk.
A wide, boxy jawline from strong masseters
Desire for a slimmer, more oval or V-shaped lower face
Jaw tension, clenching or teeth grinding and related tension headaches
Medical consultation: Assess jaw width, bite habits and facial balance.
Personalised plan: Clear guidance on doses, expectations and maintenance.
Treatment: Gentle, targeted placement for symmetrical, natural results.
Review: Early check at ~2 weeks (function/comfort), then 6–8 weeks to assess contour and plan top-ups if required.
Stay upright for 4 hours; avoid rubbing or massaging the area.
Skip strenuous exercise, saunas and hot baths for 24 hours.
Avoid hard chewing (e.g., tough steak, chewing gum) for 24–48 hours.
Mild tenderness or tightness can occur and usually settles quickly.
How it works: Precise micro-doses relax the masseter so it works less intensely. Over weeks, the muscle de-bulks, creating a slimmer, more balanced jawline. Many patients also notice relief from clenching-related tension.
At a glance:
Procedure time: 15–20 minutes
Onset: Function relaxes in 3–7 days; visible slimming builds over 4–6 weeks (peak ~8–12 weeks)
Longevity: ~3–6 months (often longer with repeat treatments)
Downtime: Minimal; day-to-day activities are fine
Chin/jawline filler: Subtle structural support or contour refinement if needed.
Skin-quality boosters: Profhilo/skin boosters/PRF/polynucleotides to improve skin tone and elasticity over the lower face.
Combination approach: Slimming the muscle plus strategic contouring can give the most natural, harmonious result. We’ll personalise your plan.
Normal eating is fine. You may prefer to avoid very tough foods for a day or two.
Yes—doses are conservative and balanced to your facial proportions.
Many see a clear difference after one session; some benefit from 2–3 sessions spaced a few months apart for optimal contour.
