What warning signs should I watch for after Juvederm injection?

Thank you for sharing your case.  You are correct, Juvederm is not a good option for treating wrinkles in the glabella.  It sounds like you are ok right now, but there are definitely cases of blindness and skin necrosis in that area.  

Any warning signs typically reveal themselves within the first 24 hours (pain, numbness, skin discoloration), so it sounds as if you are in the clear. In the future, it would probably be best to stick with Botox for that area of the face. Best, Dr. Nazarian

You are correct that the injection of fillers in the region between the eyebrows can be potentially harmful. Fortunately, you are probably safe at one day post injection. It is safer to avoid fillers in this area, but Botox can be used safely. Good luck.

Juvederm in the glabellar area do carry risks of bleeding, pain, and vision loss as it can cause intravascular occlusion of a neurovascular bundle located in this area between the eyebrows.  Not all professionals recommend this due to its risks.

Thank you for your question.  At this point if anything were to happen it would have already happened.  For your education signs of intravascular occlusion with filler would include duskiness to the area, pain, blanching, and/or vision changes.  Regards, Dr. Matt Elias

I have performed filler injections in many regions of the face including the area between the brows. If you have not experienced any issues within 24 hours, it is unlikely that you will have a problem at this point. Often it is immediate pain and blanching of the skin.

You should look out for skin discoloration, bruising, pain and visual symptoms. If something were to occur it is usually almost immediately. 

Sorry for your concern.  You would have had a problem by now if you are concerned about necrosis or worse, blindness but these events are  fortunately very rare. You may have noted blanching ( turning white) or increased pain after the injection.  Take care

The glabella area is a very sensitive area with the vessels and lends itself well to Botox. However, Juvederm is a thicker product and is not advised in the area.  It sounds as if everything is fine with you, however.  Best, Dr. Green

Warning signs after injection of a filler include severe pain or numbers, visual changes, and change in color of the skin around the injection. Usually these signs occur within the first day, if there is problem. If you are already a full day out and not having any problems, you are probably fine.
