As most of the panel members agreed, Restylane is the product of choice in our practice for the tear trough area. We like the fact that it does not migrate as easily as Juvederm, that it may be resolved with hyaluronidase if needed, comes in 1/2 syringe for those that require less product in this area (which is not uncommon), and is much, much safer than a semi-permanenent or permanent filler.
We recommend that you don't trade safety for longevity as the tear trough area is very unforgiving and requires meticulous technique and the correct dermal filler.
