Whatever you do don't do what I did
My complexion is olive too, and my stretch marks aren't silver, but just a lighter shade than the rest of me. Soooo..... I decided that I would tan them That just made it 100x worse. My healthy skin got way darker and the marks (scars) didn't tan (dahhh scars don't tan). So what I do is use a bleaching cream, and cocoa butter. The bleach lights the surrounding skin and the cocoa butter plumps everything up. Plus I use an outragous amount of lotion. My skin looks pretty good stretch marks and all.
