I had this burn after my laser hair removal session, how long it will take to heal? Would it leave scars? (photo)

I had my laser hair removal session less than 24 hrs back, noticed warm feeling after that and then redness which turned brown now. These marks are all over my bik line. Its not painful but but feels uncomfortable. I have had sessions before as well but never experience this. I am applying mebo ointment. Can you please help me with it, would these marks go? How long it will take to go? Any other ointment i can apply? I am not going for another sessions at that place for sure.
