It is common to have swelling after Restylane injections. When that happens, it seems like too much was injected, the lids may seem bumpy or blue. This swelling tends to go away over one to two weeks.
If more than a few weeks have passed then the issues is probably not swelling and the problem is probably being caused by the Restylane. In addition Restylane under the eyes tends to last a long time, often a year or more. The good news is that you can get rid of Restylane almost immediately.
The best choice is an injection of Hyaluronidase that will dissolve the Restylane completely in less than one day. The Hyaluronidase injection is an easy process that is much less to go through than the original injection because it involves many fewer injections and a very small amount of medication injected.
You should have no permanent changes from the Restylane if you let it dissolve on its own or if you speed things up with a Hyaluronidase injection.
Hope this helps.
