Can Repeated Use of Botox Jaw Reduction Lead to the Sagging of the Masseter Muscles Overtime? (photo)

At Boris Cosmetic we have seen excellent results from Botox for the masseter muscles. Enlarged masseters are often seen in people who grind their teeth, and can cause a square, heavy look to the face. Regular use of Botox can cause the muscles to be smaller and less prominant, which makes the face appear slimmer. It does not cause the skin to sag. The dose must be calculated by your doctor when he or she examines you. 20 units is a reasonable dose to begin with. It takes time for the treatment to show, and must be maintained every 4-6 months to continue working. Good luck.

    Botox can be administered in doses of 25 units to each side.  The masseteric bulk will be reduced over about a year's period.  The skin sagging and jowling is not an effect of masseteric debulking.

Twenty units per side is less than our recommended dose, however you'd need to have a consult and assessment first to determine your goals. It takes regular treatment to those muscles, and we would want to see you after 90 days. No, it won't make your skin stretch out.
