I had diode laser hair removal treatment 2 weeks ago and 2 days earlier, got burn marks. Please advise. (photos)

I had diode laser treatment (2nd session) 2 weeks earlier. 2 days ago, I shaved normally, but overnight I got burn marks and it was burning. After a warm bath, the burning was not there, but burn marks are present. Can you please look at the attached images and advise if these scars would be permanent and what should I do to get rid of these?
