Dear Doctor
Please can you tell me somthing about botox as it is used in the platysma bands of the neck:
1. Is it true that the lower down in the face it is used, the longer and stronger the effect? If so, why?
2. Is it also true that after several uses the muscle eventually stops contracting (and can you then avoid neck surgery)?
3. Is it necessary for this injecting to be done by a surgeon as I have read somewhere due to proximity to the vocal chords etc?
Thanks for your good advice.
Yours sincerely
SF
