I had three vials of Juvederm injected in January. I'm very pleased with the results and I plan to go back for more when I have the money. The past several weeks I’ve had intermittent itching and what looks like burn marks on my chin. Is this normal or is something else and just a coincidence that it happened shortly after my injections? I use Retin A, but I've been extremely careful not to get this anywhere near the problem area. I'm sorry, but I don't have any photos.
