Blue lines after Juvederm are usually a result of the product being placed too shallow and so you get the Tyndall effect. It is hard to comment on how long they will last, but it's usually not as long as you have stated. Do you have photos? A bit of hyaluronidase injected correctly by a trained physician could remove the blue areas almost immediately. Otherwise, you will have to just wait for the product to go away on its own.
