Can Juvederm Cause Permanent Damage? How to Remove from an Area That Was Not Supposed to Be Applied?

Juvederm will not cause permanent damage. It is a temporary filler, and lasts 6-7 months on average. What area were you trying to improve, and how long ago did you have the injections? Swelling will be present right after the injections, and you should give it a little time before coming to any conclusions about the result. If necessary, the enzyme hyaluronidase can be used to dissolve the filler, and you will look the same as you did before the injections. I would recommend visiting the physician who performed your injections, as he/she will be able to examine you and answer any questions you have. Thank you, and best of luck.

It sounds like you are very swollen.  It is unlikely that you could have received enough Juvederm to change your whole face. Juvederm is not permanent nor does it cause permanent damage.  It is temporary as well as reversable with Hyaluronidase but I would recommend waiting another week for all the swelling to go down before deciding your final results.
