yeah i wouldnt get cautery done for raised scars. it can leave indents in the skin and make them look a lot worse. i would definitely massage them with vitamin e daily and see what happens. i'vae heard when the scars are newer that is the best thing to do. i think it takes a few years for them to fully mature.
i wish i would have done that with my raised scars but i am trying that now before i book my appointment for dermabrasion. i figure at this point it cant hurt.
