I had a treatment for laser hair removal yesterday and now have a burn. Is this permanent?

I had a treatment for laser hair removal a yesterday and am very worried i may be permanently scared or discoloured. I guess the Alexandrite laser was set at too high! I have attached a picture and would love to get some advice on how bad the damage is and what i can do to get back to normal if possible. Unfortunately it seems anyone with or without training can perform the treatment. I wish i knew this before and hope I am not damaged for life.
