Treating the hollow area under the eyes requires a great deal of skill. However, many patients get excellent results with the correct treatment.
Any filler will add volume under the eyes. The issue is which type of volume enhancement is the best option. In my opinion the best option for under the eyes is Restylane.
Juvederm is any excellent filler. However, in some patients Juvederm tends to swell. This can happen with Restylane as well, but that is much more uncommon.
The big advantage of Restylane (and Juvederm) is that it can easily be dissolved. No matter how skilled the cosmetic surgeon, some patients need a touch up and that is easy to do with Restylane and Juvederm.
Evolence is collagen based. For that reason it can not be dissolved. If there is anything that you don't like about the treatment, you would need to wait for the product to dissolve on its own.
Hope this is helpful.
