I have streak marks on forehead and cheeks after my first IPL Treatment. (photos)

2 weeks ago I had my first IPL treatment. Im left with streak marks on my forehead and cheeks. I was initially told by the RN that I would need multiple sessions to lift the dark spots from pregnancy hormones. I feel that it is quite obvious that they missed numerous places on my face and did not give me an even treatment. They said this is normal and that is why they suggest multiple treatments, that with my next treatment they will go the opposite direction to capture the remaining dark areas
