The lower eyelid lines are commonly caused by skin aging and mid face descent which accentuates a natural groove in this region called the tear trough. This area is the transition between the lower eyelid and the cheek. As the face ages, the cheek fat descends and this hollow area is revealed. It can be corrected with volumetric fillers for mild to moderate aging and a midface lift or cheek lift for moderate to severe lines. I would recommend a hyaluronic acid based filler for this region, and a combination of Juvederm, and Voluma or Perlane would be great. They are smooth and reliable, and they can be dissolved if needed. Sculptra is a biostimulator and activates collagen deposition in the areas of injection. Sculptra is great for the temples, cheeks and chin, but may lead to nodularity and unreliable volume in the lower eyelid.I hope this helps!
