I started using black soap a couple of days ago and I just want an approximate of how long it will take to remove my acne scars.

I don't think it 'promises' to clear up acne scars; black soap only exfoliates gently, not enough to remove scars. For this you need laser surgery or deep exfoliation over a long period, i.e. skin peels.
