I am a 24 yr old female with really bad acne. What can I do or take to clear it up? I have pcos

Talk to your doc. Pcos can cause abn elevation in testosterone which can lead to acne. I would talk to your doctor or endocrinologist to see if the pcos can be treated. In the meantime i would see a dermatologist because as long as the testosterone is high, the acne may be hard to control and not respond to otc agents.
Tough one. The acne is caused from the over production of hormone (androgens) with your pcos. Oral contraceptives or birth control will help with both acne and pcos.
