Masseter injections and facial slimming injections are the same treatment. The masseter muscle is the muscle responsible primarily for chewing and is shown in the picture below.
We treat facial slimming and tooth grinding by injecting anti-wrinkle product into the masseter muscle. This causes the relaxation of the muscle and slims it down. Imagine going to the gym and doing weights for months then stopping gym for 6 months.
That is the way the treatment works – by reducing the ability of the masseter muscle to contract it reduces the size of the muscle and causes a slimming effect.
