Hi London2011,
Injecting Restylane or any other injectable filler to the upper eyelid hollow is considered "off-label." This means that the filler is not approved for this usage. I firsted started treating upper eyelid hollowing in 2006 with fat grafting. I began doing this as part of my upper eyelid surgery. In addition, to removing a conservative amount of skin, I was also adding back fat into the upper eyelid hollow. In 2008, I had a patient who did not want to have an upper eyelid surgery for fear of keloids. Her main issue was really the hollowing. However, I did not have a way to place the fat into the upper eyelid hollow.
I thought was possible to use Restylane in the same manner as I was surgically placing the fat, so I did a test session using Injectable saline. This filled the area nicely. A couple of weeks later, I followed that up with Restylane injections.
Most patients will upper eyelid hollowing, have too much eyelid showing, in particular in the inner corner of the eye. This can also be worsened with a doll's eye deformity, where there is so much hollowing of the upper eyelid, that it causes the upper eyelid skin to vacuum inside of the eye socket. This can result in an older looking eye, especially when the person's eyes are closed.
The main risks, are lumpiness and overcorrection. I believe there is a correct way to inject the upper eyelid filler, to simulate the configuration of the upper eyelid brow complex of youth. The upper eyelid complex is 3 dimensional, but since the upper eyelid opens and closes, it is really 4 dimensional. It should not only look normal when the eyelids are open, but it also needs to look normal when the eyes are closed. If the injection is performed in the wrong pocket, it will look very lumpy when the eyes are closed, and you can see where the filler injection ends.
I get emails from people all over the world. I have seen photos of patients with improperly injected in the upper eyelid area. They usually show a photo of their eyelids when they are closed, and the filler can be clearly seen.
If there is not enough filler injected, it is easy enough to add more.
