Botox
Botox is a medicine that weakens muscle contraction. It is effective for five to six months.
Feature :
The masseteric fascia is located on both sides of the face. When Botox is injected to this muscle, contraction is weakened and the muscle volume shrinks to correct the square jaw.
Self Diagnosis :
Bite tightly just as you crush something between your molars until the jaw has humps on its sides. They are the masseteric fascia. When Botox is injected to this muscle, it shrinks to reduce the side volume of the face.
