Overview

Masseter Botox or Dysport reduces the strength and size of the jaw muscles. It is ideal for those seeking facial slimming or relief from jaw tension, teeth grinding (bruxism), or TMJ discomfort. The result is a softer, more contoured lower face and less muscle strain.

What to Expect

• Treatment Time: 15–20 minutes
• Sensation: Slight pressure or pinching; minimal discomfort
• Side Effects: Mild tenderness, swelling, or bruising possible
• Visible Results: Functional relief in 7–10 days; facial slimming in 4–6 weeks
• Duration: Relief lasts ~3–4 months; slimming effect may last longer

Pre-Treatment Care

• Avoid alcohol, aspirin, ibuprofen, and fish oil for 48 hours
• Do not chew gum or engage in heavy jaw activity prior to treatment
• Disclose history of jaw issues, dental work, or facial surgeries

Aftercare

• Refrain from applying pressure or massaging the jaw for 24 hours
• Avoid excessive chewing, gum, or clenching for a few days
• Skip workouts, heat, or lying flat for 4–6 hours
• Resume normal activity and skincare the following day

Contraindications

Do not undergo treatment if you:

• Are pregnant or breastfeeding
• Have a history of facial nerve damage or jaw surgery
• Have a known allergy to botulinum toxin
• Have difficulty chewing or swallowing
• Have any neuromuscular disorders

Additional Notes

• Facial slimming results build gradually and are most noticeable after a few weeks
• Often combined with chin or cheek filler for overall balance
• Continued treatments may reduce grinding and tension long term

Masseter toxin should be performed by experienced injectors who understand facial anatomy and function. All clients require a clinical evaluation. Individual outcomes vary. Not all patients are candidates.
