Will Botox results in my face be ruined by a deep tissue massage in my neck and throat 4 days after?

Hello, and thanks for your question. Any injectable filler such as Botox that is administered to the face should not have any effect on other parts of your body. It is actually absorbed by your body fairly quickly, so you would certainly not have any issues from it after 4 days.
If you are concerned about tingling sensations or any discomfort, let your doctor or a specialist know what you are feeling. They will be able to give you an examination in order to let you know for sure.

A deep tissue massage to your neck would not affect results from a Botox treatment to your face 4 days earlier.  

Hi there, The results of your botox treatment will not be affected by a massage done 4 days post injection. The botox would be absorbed by the muscles at the time of your massage, in fact, it is unlikely that botox would migrate as soon as 4 hours post injection.
