Masseter Botox - is 5 Units Per Side Enough? (photo)

For masseter treatment, 5 units is small and certainly not likely to harm you.  Generally, I start with 15 units per side.  In looking at your photo, I wonder if you might do well with other approaches.  Before prescribing yourself a treatment which is essentially what you are doing, you might consider having an actual consultation to see what a cosmetic surgeon recommends to help you achieve your goals.

If you really have masseter hypertrophy, and are hoping that reducing it with Botox will make your jaw look less wide, then 5 units is insufficient.  25 units per side works well depending on the size of the muscle, but would be appropriate for most women.
