Restylane in the upper eyelid stays longer than in pretty much any other place on the face. I routinely see patients back after longer than a year and the upper eyelid filler is still looking good with hardly any need for a touch up.
Because of the fact that filler lasts such a long time in the upper eyelids, combined with the precision and accuracy of the fillers, I believe it should be the treatment of choice in restoring upper eyelid volume over the use of fat. I think fat injections are more useful when it comes to total face rejuvination and are not worth the investment when only one small area such as the upper eyelids is to be treated. Fat injections are also not as predictable as the fillers thus necessitating possible touch ups and tweaks in the future.
Below is an example of a patient before and 3 YEARS AFTER Restylane injections into the upper eyelids to restore volume and correct an asymmetry caused by a previous eyelid lift by another surgeon.
