Laser hair removal reaction on legs. What is this? (Photo)

Hi, I had my third session of laser hair removal a few months back and have had an awful reaction which the clinic don’t seem to know what it is. Originally it was pigmented reg patches, then I started to peel/ crust, now it’s turned to painful cracks in red showing all up my legs (up to my knees). The clinic (well-known) don’t seem to have a clue and I really would love some help.
