Scar Question/Mederma for Kids

[Coila]

I am feeling a little sick to my stomach right now. Awhile back my son was bitten by a dog right on his face. Here is a picture a day or two after it happened back around Christmas time.



And here is what it looks like now.



Anyway my mother came by tonight and told me that it would probably always be a scar. I thought that since he is small still and has a lot of growing left that it would fade away and be barely noticable. Am I wrong?!

Have any of you used Mederma for Kids and has it worked for you?? I am scared my little man's face is always going to have this scar now!
