Has anyone used Mederma? How did it work out? I've got two scars I'm concerned about... One on my forehead from a fall I took a couple of months ago which is right at the hairline but rather large (I basically took off the top layers of skin so it's not a raised scar from a laceration). The other is on my chest (sternum basically) that is a very raised, very old chicken pox scar. I'm sure the one on my forehead could be covered up with make up if need be, but short of pushing "the girls" up so far that the chicken pox scar is buried in cleavage, I'm not sure what to do. Will Mederma even work at this point?
