acne
"Having been on Estelle-35 for nearly a year (which gave me the worst acne of my life, 10 x worse than it already was), I decided to change to Yaz. I'm in my third month of taking it and I think I've broken out (4-6 spots at the same time) twice, whereas before I was getting 4-6 new spots per day. No initial breakouts. Only had one cyst in nearly three months.

The only side effect was my fault - I didn't wait until my period to start taking them and had breakthrough bleeding for around three weeks. 

I haven't experienced any weight gain, headaches etc.

If you're deciding whether to try the pill for your acne, just do it. Seriously. It's done wonders for my confidence and anxiety, and I can actually look people in the eye now!"
