acne
"I'm a 28 year old woman who switched from oral birth control to the Mirena IUD.  That is the only change I can associate with a horrible bought of hormonal acne that started about 6 months after I made the switch.  I had embarrassing, painful acne along my jawline down onto my neck.  My skin was greasier than normal and products that would typically keep my breakouts at bay didn't touch the cysts on my jawline and neck.  I've been taking 100mg of Sprio for about 6 weeks now and I've already seen great improvement.  My skin isn't 100% yet but it's obviously improving and I assume it will get even better with time.  I haven't experienced any side effects, no weight gain, dizziness, or breakout period."
