Help! I have a raised keloid scar that I want to flatten?

I have several keloid scars on my stomach from having gallbladder surgery, they did it laparoscopically so I have 4 little-less than an inch keloid scars. I used plain vitamin E oil for months ir seemed, maybe even longer. They are completely unnoticeable now. I can still feel them but they can't be seen by my husband. He laughs because I don't have to look to point them out but he has to look really close to see them, I wouldn't use the silicone at all. Good luck, I hate keloid scarring!!
