This complicaation is immediate (and rare!). So please cut yourself some slack and stop worrying! I hope you are enjoying your results!
There is no need to worry after 10 days about vascular occlusion from Juvederm. It would happen immediately and would present as very pale skin. Later it can appear mottled, bluish, and the late stages (a couple days) it will be black (dead skin). It's cause is either the filler filling the vessel or pressing on the side of the vessel to crimp it. It is rare but does occur. An experienced injector should be able to recognize the early signs and reverse the problem right away. Steven Weiner, MD, Facial Plastic Surgeon, Destin, Florida.
I have not seen any reports of vascular occlusion with juvederm. There was a case reported years ago of collagen causing an occlusion. Unlikely move on
Vascular occlusion is immediate. The filler has to be actually injected directly into the vein or artery, causing the blockage. It cannot move in there by itself after the fact. You can stop worrying about this for this procedure.

Vascular occlusion is something that you would see very rapidly following your injections. Given that fact it is virtually impossible for this to happen 10 days after your injections.
