There are several options for filling in your lower eyelid grooves, and smile lines. Hyaluronic Acid products like Juvederm and Restylane are the most popular. Radiesse is another good long-term filler, but it too is temporary and expensive.
You might consider researching doctors skilled in the art of Silikon-1000 injection. This is a permanent filler and would be an "off-label" application of an FDA-approved device. It needs to be administered only by a physician that is experienced with its applications for cosmetic enhancement. You should see many favorable before and after photos, and you should be completely comfortable with your decision since results, good or bad, are permanent.
