From your photos, it appears as if 1 cc of Restylane would be enough to get the improvement you are looking for. A 3-D in person consultation is always best. Good luck to you.
I would recommend using a single 1cc syringe and placing 0.5cc under each eye. This should give a nice natural look. A product such as Restylane Silk would do very nicely. Be well, Dr. M
