Hi @hambino! Most facial filler products that are injected into this area should ideally be placed in the tissue plane directly on top of the bone, or at least underneath the eyelid muscle layer. If a facial filler product is placed too superficial in the skin, or on top of the muscle layer, the product may settle in with an abnormal appearance and can look to be lumpy, swollen, or irregular. The filler products that are preferred to treat this area will have some degree of affinity for water molecules so all of these products will exhibit some degree of hydration and swell once injected into the body. Hyaluronic acid facial filler products that were previously injected into an improper tissue plane can be dissolved by hyaluronidase injections. Best of luck, Dr. Nima!
