A Hi Nikki, thank you for your question. Botox in the masseters can be highly effective in achieving a more slim or tapered face. Because the masseter is a larger muscle than say the muscles in the forehead or around the eyes, it usually requires higher doses than what is typically used for cosmetic injections elsewhere in the face. That being said, 6 units to each masseter seems pretty low considering how large the masseter muscle can be in some individuals. While everyone will require different dosing, it's more common to inject between 15-40 units of Botox per side. I often recommend patients start with a conservative treatment, 15-20 units per side and then follow-up in about 6 weeks. At that point, more product may be needed. I recommend a follow-up again in 3 months to see if additional treatment is needed and then at that point most patients can return every 6 months for treatment. Keep in mind because masseters are larger than facial muscles, the result can take longer to set in and appreciate (around 6 weeks) than in the forehead or eyes (5-7 days). Regardless, make sure you consult with someone who is comfortable and familiar with masseter injections. Good luck!
