Donald B. Yoo, MD, FACS · Answer

Botox for masseter reduction works by relaxing the masseter muscle and not allowing it to "work out".  Just like any muscle in the body, during the 3-4 months the Botox is active the muscle will atrophy.  After the muscle regains its movement, it will again be able to grow in size.  Most patients will receive treatments every 4-6 months to maintain the slimming effect.

Lawrence Osman, MD · Answer

Botox reduces masseter size by causing atrophy of this muscle.  As the Botox wears off, portions of the muscle can regain size again as it repeatedly contracts with chewing.
