What to Do About Redness at Botox Injection Site?

I would report this to the injecting physician to rule out possible infection. An allergic reaction is possible but highly unlikely.

What do to about redness at Botox injection sites depends on how long ago your treatment was.  If it was an hour ago or even yesterday, I would not worry yet.  If it is several days or a week and getting red, inflamed or tender then it's possible that you have something more serious going on.  Call your physician and set up an appointment to review if it's the latter.

It is very common, and expected, to have a very tiny red bump for several hours to even a day after the botox injection, but if it persists thereafter, it probably is a small bruise that will go away in two weeks. Infections are extraordinarily rare after botox injections, and should they occur, they would not be present immediately after the injection but there would probably be a delay of a few days before its onset. If there is pain, especially without touching the area, and redness then infection may be present and you should call your doctor. Bruises are red or purple and some will hurt when touched.
