I don't know if you have ever heard of Neosporin® Scar Solution™, Teri, and all I can go by is their own commercials, but they claim to help the appearance of old scars and to prevent scarring with new surgeries. Not meaning to advertise here, but was wondering if anyone had ever used this. I tend to scar moderately easy. I tend to lay that on to being diabetic. I have not had bypass surgery, however. This is a very interesting question. Thanks for asking it.
