Lumps on forehead after Botox injections? When will they go away? (Photo)

I have seen this 3 times in the past.  They go away but take 6-8 weeks.  Massage and warm compresses help.  I think it is an allergic reaction from the injection not necessarily from the Botox or the saline itself.  I would avoid more injections, steroid or otherwise.  Best, Dr. Emer.

My best guess is that these are a reaction to being stuck not to the products. In response to some of the above about preservatives in saline; I think that most injectors use saline WITH PRESERVATIVE to reconstitute Botox. The benzyl alcohol(the preservative) is the reason why Botox injections do not sting.

The saline used to reconstitute botox should be preservative free saline.  There is nothing in it to be allergic to.  The botox may have been contaminated, or your skin may have had a bit of soap or other substance that was introduced into your skin with the needle puncture.  In any case, I would use massage and warm compresses now and let your body heal.  It may take a week or two for the lumps to disappear, but they should.
