Volume loss under the eyes can make you look tired. Restylane L is a great product to fill that area to give a refreshed look. On average 1 - 2 syringes usually does the trick. We always underfill slightly, as to not overfill as the product settles and improves over a 2 week period. The example in the picture, I would have the patient come back at two weeks to see if an additional amount of filler is needed.
