Burn scars after laser hair removal. What can I do? (photo)

I am getting married in 2 months so got a laser hair removal treatment done on my chin as i was very unhappy with the dark spots due to undergrowth. But i think my dermat burnt the area. He says he gave multiple passes for better results. Now I am very scared that the burn will leave scars. I am using Strataderm and Mederma on the marks. They itch sometimes but normally they are ok. Is there a way to get rid of these marks quickly. I am getting sleepless nights because of these
