Slim the lower face by relaxing jaw muscles

20–40 units of botulinum toxin injected into each masseter muscle, causing gradual atrophy over 4–8 weeks. Overdeveloped masseters — from jaw clenching, teeth grinding (bruxism), or genetics — widen the lower face and reduce jaw definition. As the muscle reduces in bulk, the lower face narrows and the jawline becomes more tapered and angular. Results last 4–6 months initially; with repeat treatments the muscle atrophies more permanently and intervals extend. An additional benefit for bruxism sufferers is significant reduction in jaw pain, headaches, and tooth wear.

Square lower face to V-shaped jawline in 6 weeks. The transformation in photos is extraordinary and it also stopped my morning headaches from grinding.

3 rounds in and the muscle has significantly reduced. Intervals getting longer. Best injectable I've had by a significant margin.
