Does aloe vera gel, cocoa butter lotion, or vitamin e oil heal mild scars on the face and body?

Possible: There is no proven scar healer out there that I am aware of, keeping the area clean and soft should help with decreasing the amount of scar build up. I have always thought that sunblock for the first year on a scar is important to avoid excessive scarring as sun damage can exacerbate a scar. Most scars overtime though do improve, the body usually does a good job at healing itself.
