What can I do to treat skin atrophy and depigmentation following two rounds of triamcinolone injections? (Photo)

Last month I received treatment for a delayed inflammatory reaction to HA fillers in the tear trough/ cheek area. Over the course of about six weeks, the dr used vitrase in the cheek area to dissolve any remaining filler product. he also administered two rounds of diluted triamcinolone to reduce lymphedema. The kenalog injections were administered about 3.5 weeks apart. A few weeks later, I've got discolored divots and hypopigmentation all across the cheek region. What is my recourse?
