Anyone tried Mederma ? A friend gave me a tube of it the other day. I recently acquired a new scar on my chin, thats why she gave it to me. I burned my chin on a hot piece of 1.5" HREW tube that had just been welded I also have a scar between my eyes from a rifle scope biting me. Also have a sizeable scar on my wrist from an air grinder. Also have the brand on my wrist. I'm trying it on all of thse to see how it works out. So thats 2 recent scars and 2 old ones. Anyone had luck with this stuff? She gave it to me cause she says it works, forget what she used it on though.
