I have been using biotin, and I think I have gotten good results. Well, it may be a combination of the vitamins I take(particularly biotin) and the way that I take care of it. My face really doesn't break out, fortunately. Like you, I drink a lot of water. I think the key to taking biotin is to not take it by itself, and to play with your dosage. I don't think that it is good to start taking it in a large dose without seeing how your body--especially your face--will react to it. HTH!!
