Oh yeah, use the Mederma when you are all healed up! I have the kind with SPF in it. I didn't use it as much as you were supposed to though and I mostly used it on my wrist when I did but I think it helped! And wearing sunscreen or whatever (I was told SPF 50 or higher so I have Neutrogena SPF 70 and 50, in the radiated areas) will help keep your scars from getting too dark if you spend a lot of time outside.
