What is under-eye light filler?

Under-eye light filler is a filling application made with cross-linked products containing hyaluronic acid in the area where there is sunkenness under the eyes. The area under the lower eyelid, from the point where the nose and the eye meet, which we call the medial canthus, to the corner of the eye extending to the temple area, which we call the lateral canthus, is the under eye area. Under-eye light filler is a name and it sounds nice. The reason why it is called this is because the hyaluronic acid-containing fillers we apply to the under eye reflect the light better and give a bright effect to this area.
