Jaw Botox (Masseter & Mentalis Toxin Treatment)

 

671. Jaw Botox (Masseter & Mentalis Toxin Treatment)

Jaw Botox involves injecting botulinum toxin into the masseter or mentalis muscles to reduce overdeveloped or hyperactive jaw muscles. In Korea, this is often called “square jaw Botox” (masseter) or “chin tip Botox” (mentalis).

▶ Indications for Masseter Botox:

• Enlarged jaw from chewing hard foods

• Bruxism or jaw clenching habits

• Overdeveloped salivary glands from long chewing habits or chronic stimulation (e.g. spicy/salty food, gum, jerky, alcohol)

Masseter overuse leads to muscular-type square jaws. If prolonged from childhood, it may also affect bone growth, resulting in skeletal square jaws. Long-term chewing can enlarge the parotid gland, while alcohol stimulates the parasympathetic system, further enlarging salivary glands and potentially causing alcoholic parotitis.

▶ Therapeutic effects:

• Jawline contouring

• Bruxism prevention

• Relieves TMJ pressure

• Reduces gummy smile (via mentalis Botox)

• Smooths "orange peel" chin wrinkles caused by mentalis overuse (e.g. frequent pouting, retruded chin, or lip-sealing effort)

▶ Treatment details:

• 3-point injections on the lower masseter

• Dosage varies: low (first-timers), medium (bruxism), high (jaw slimming)

• Adjust dosage for asymmetry; evaluate chewing side habit

• Lasts ~3–6 months depending on muscle activity

• Chewing gum or tough food shortens effect duration

• Softer foods help maintain results

• Repeated early injections may cause antibody resistance, so spacing out sessions is key for long-term use

✨ Jaw Botox reduces overworked facial muscles, reshapes the lower face, and corrects habits like clenching or pouting.
