birth control
"In high school I took Loestrin 24 FE and never had any skin problems, my skin was always clear. I was switched to Lo Loestrin which has lower hormones and I guess it messed up all my hormones because I started breaking out in the worst cystic acne. A new pimple would come up every day. Now it is out of control and I'm starting to develop dark spots (scarring) from the cystic acne. "
