The mandible contour plays a very important role in the beauty and youthfulness of the face. Repeated contraction of the depressor muscles of the lower third of the face and neck is one of the important causes leading to loss of contour in the jawline area. By relaxing these muscles, botulinum toxin A (BoNT-A) injections on the lower face can help postpone plastic surgery to improve the area and also bring a rejuvenated aspect for those patients who are not willing to undergo surgical procedures. It is most likely that repeated treatments starting early in the aging process will avoid muscle shortening and therefore have a very beneficial impact in preventing the changes that lead to loss of contour. The masseter muscle defines the posterior jawline, and its hypertrophy is an undesired feature especially for Asian females. BoNT-A has successfully been used to reduce masseter muscle mass and change the contour of the posterior mandible. Physicians have to be educated on the importance and potential benefits of treating the lower face with BoNT-A.
