Do I really have to sit up for 4 hours after Botox? Do I need to make the required facial gestures continuously for 4 hours?

The theory of not lying flat or bending over for a few hours after Botox or Dysport was mentioned by some of the pioneering doctors who developed the clinical uses of botox.  It was thought that the positional changes might induce diffusion of the Botox to unwanted nearby regions and cause unwanted relaxation of other muscles. 

It was also mentioned that purposeful contraction of the muscles that cause the overlying unwanted wrinkles, could help bring the neuromodulator into the muscle-nerve junction which is how Botox blocks the signal from being transmitted and the muscle then doesn't contract.

Neither of the above recommendations have been proven to be necessary but many doctors still recommend them.

After Botox treatment there is no specific after care required. Obviously we ask our patients not to massage or manipulate the areas for the first day but no facial exercises or physical restrictions are required
