Will my skin tighten up again after masseter Botox?

Thank you for sharing your question. Once Botox wears off you should return to your pre-Botox appearance assuming your clenching returns. I would still expect some additional slimming if it has only been two weeks since treatment.

The results from masseter botox appear pretty quickly after injection. The face does look slimmer but one trade off is as you flatten the lower cheek, there will be some loosening of the jawline skin and soft tissues. It’s like the opposite of fillers which tend to volumize and hence lift the tissues. Depending on your age, you may get some contraction of the overlying skin but not very significant tightening like a mid face or jawline lift would do. Usually the slimming effect creates more of a “V” shaped face and looks better despite the slight descent of skin.
