Swelling and redness after Botox (Photo)

Your best course of action is to ask the office what they did differently. If they used a new manufacturer of saline, or different needles, they could have introduced something into the treatment that you're reacting to. It might also be a good idea to have an allergy test and find out exactly what you're sensitive to for the future.

Hi AKF. Although there is some redness and swelling after Botox injections, what I see in your pictures does seem to be a bit excessive. Though true allergy to Botox is rare, you are correct in suspecting that this might be related to whatever was used by your injector to dilute the Botox (especially if you used a different injector than usual). You can use benadryl or hydrocortisone cream to see if it helps, but I would notify your injector in case he/she wants to see you in person. Best of luck.

from your photos it appears as if you might have an allergic contact dermatitis.  This would most likely result from whatever was rubbed on your skin, perhaps prior to your treatment to cleanse it.  Find out what they used and if it was anything other than alcohol you might be allergic to it.
