Abnormal healing/scarring from Picosure on body? (Photo)

Hello, I had one session of Picosure laser done on my lower body (buttocks area) to remove stubborn post inflammatory hyperpigmentation. I was told I would only be mildly red for a few hours, and that the settings were safe for my olive skin tone (Fitzpatrick 4). However, it looks like my skin has been damaged after a week and a half. Is this normal healing, or could it be permanent damage or lead to hypopigmentation?
