You appear to have two issues with your lower eyelids. The filler that you are having injected, when done well, will significantly improve the hollowness of your lower eyelids. The bunching of the skin, and the crepey appearance of your lower eyelid skin may not respond to under eye filler. The crepey appearance of the skin is due to laxity of the skin itself, not loss or herniation of fat in the lower eyelids which causes the hollowness and bulging. I would ask about specific treatments such as, laser resurfacing, or even a medium depth chemical peel to the lower eyelid skin which will specifically and effectively address the lower eyelid skin quality.
