Birth control made my hormonal acne 10x worse than it had ever been, even after taking it for half a year. I take 50mg of spiro every day and now I am finishing my first month - my skin is way noticeably clearer. Less and less breakouts every day, and they go away much faster. The dehydration isn't even enough for it to bother me, and drinking water is good for your skin anyways. Using this as a supplement for Ortho Tri Cyclen, and also using Aczone as a topical which has worked wonders.
