Masseter botox injects botulinum toxin into the masseter (chewing) muscles at the angle of the jaw. As the muscle relaxes and reduces in size over weeks, the lower face looks slimmer and softer. It can also help clenching. At Louave in Cheongdam, Gangnam, Seoul, the dose is adjusted to muscle size.
