Depressed/Indented scars on the forehead. Any suggestions? (photos)

Hello, I just had a motorbike accident and of course a new small scar on my face (forehead/see pictures). Knowing that I have 4 scars in total (upper face), I would like to do smthing about that. They are all depressed/indented , and the last one looks like a wrinkle, I read many articles on the net and I still don’t know what is the best solution in my case: "Fill in" this scar? Make it smooth with laser/peeling? Any suggestion on the method to follow is welcome. Many thanks, JB
