Botox in masseter muscle top-up? (Photo)

Thank you for your question and photos. There is no reason to get more Botox injections until you feel like you are ready for them, but I am starting to see a slight bulge in the masseter area, especially on the left. You are correct in the assumption that additional treatment will slim the lower face more, but a lower dose may be just the right solution. You may want to wait another 4 – 8 weeks until you can feel the hard bulge of the muscle and then try 7 – 10 units per side. This quantity should knock the muscle back down without excessive narrowing. It won’t last as long with a small dose, but why risk looking like an alien? An experienced dermatologist should be able to assess you an administer just the right dose. 

If you are still happy with the results of your treatment I would wait until you feel you need further treatment.  Typically the Botox effects wear off around 3 to 4 months, so you have gotten a lot of longevity out of your original treatment.

I usually inject botox to masseters people have overdeveloped masseters due to genetics but mainly due to jaw clinching or grinding. When getting botox to jawline for slimming you are actually weakening and thinning the masseter muscle which slims the face but can actually hinder chewing function. Unless you had overdeveloped masseters or jaw clinching/grinding teeth to begin with I would leave your jawline alone. Just looking at the photo I would not do anything at all.  Adding more will give you a thinner face which seems like you are trying to avoid. Sometimes people like a heart shaped face rather than a squared off jaw but its more of a personal preference. Its also hard to determine of chin filler is needed because you need a side profile to look at symmetry and do not want an over injected chin. I would let the provider determine if chin filler is needed.

Good Luck...

Hello and thanks for your question. Thats great to hear you had a good result from a relatively small number of units in the masseter. The best approach if you're worried about having an exaggerated effect would be to start with a lower number and work up- You can always add more botox but you cannot take it away. Always go to a qualified and experienced practitioner for any injectable treatment, best wishes
