What are strange remedies that you have tried on acne and acne scars?

So far I found that a scrub made from cod liver oil and garlic powder work amazing! I've never seen such fast results for acne. The scars kind of jist fade on their own. So, what strange remedies have you tried that have tried?

Oh yeah, my reasons for using cod liver oil is for the vitamin A and the reason for the garlic powder is because it is anti fungal.
