and thir not so much anymore since i've been using a bleaching creme.I just bought bio oil and im balck and wanted to know if it works for acne marks.?
I don't know how it works on black skin, but I've been using it for about a month and a half on acne scars and it's made a huge improvement!! I used to have acne on my lower back, and they left scars when it cleared, so I've been using bio oil there and now they're totally gone, seriously. My mum couldn't believe it when I showed her, especially as they'd been there for such a long time and took only a month to clear up! :D
