"was on this for about a year, completely cleared up my premenstrual acne. normally i would only get a couple pimples before each period but this medication didn&#039;t cause any, great clear skin. normal periods, light to moderate lasting about 5 days. no out of normal weight gain, no headaches or mood swings. i&#039;m only giving it 9 stars because it really dried me out down there, needed lube sometimes. other than that, i&#039;d recommend it if you have a tendency to get premenstrual acne."
