Botox to massters a month before chin/neck liposuction?

In my experience injecting Botox or other neurotoxins into the masseters causes a small amount laxity, sagging on the lateral [ outer ] jaw line.  The effect is temporary and last about 2 to 3 months. The injection will not really change what can be treated with the chin liposuction but it can slightly alter the jaw line appearance.  I would recommend you discuss this with your liposuction surgeon.  Good luck.

You are having surgery in a month to reduce lower face/neck contour.  The botox to the masseter will reduce the lateral jaw line volume.  Why complicate your surgeon's work. I for one would be pretty annoyed with you if you did this as my patient.  Contact your surgeon before you do this.  My vote is to wait on this until after the surgery.  Perhaps you won't need this service.  I would be very cautious about aggressive botox treatment around the mouth.  Some injectors think this is great until there is a problem.  Correctly done, masseter botox is useful service in the right individual but not just ahead a surgery with the goal of sculpting this area.

It is not a good idea to change the landmarks that your surgeon is going to need to perform the best results from your liposuction so i would suggest you not have it done
