Are my burns from laser hair removal permanent? (Photo)

I had a laser session yesterday for my arms and was badly burned. This is my second session- I did not burn after my first session, probably because my skin was lighter. What should I expect? Will it heal normally? I am using silver sulfadiazine cream (1%) several times a day, and avoiding sun exposure at all costs!! But I'm worried that it will leave permanent scarring...what do you think?
