Masseter Botox (jaw slimming / square jaw reduction)

₩69,000from 14,109 reviews470 clinics
Botulinum toxin type A is injected into the masseter muscle at the mandibular angle so the muscle contracts less and gradually loses bulk, which narrows the outline of the lower face. The change comes from muscle atrophy, not from any change to the jawbone.
