Reverse fat grafting - Will there be a direct scar? (Photos)

How does one reverse fat grafting? I understand it will be encased in scar tissue, so normal liposuction does not work. Steroid injections are unpredictable. I have a pocket of fat grafting in my forehead and my cheeks I need removed. I think it's above the muscles. Will there be a direct scar? Should I get forehead fat removed at the same time, before, or after as my hairline brow lift that will help raise brows and decrease wrinkles, caused by fat grafting?
