yes! in my personal experience, the yaz really does help with oil production and acne. I also have very oily skin that just can't be dried out not matter what topicals i use (although they do help with the acne - differin, benzoyl peroxide, sulfur, etc.) I started Yaz about a year ago for irregular periods and it helped with that and my acne. i have since stopped the yaz and the day i stopped the oil came right back - and the acne. i never got a cystic pimple while i was on Yaz and it reduced my oil production by almost half! i'm actually going to start back on it today and looking forward to better skin!
