birth control
"I used Aubra for two functions: as a contraceptive, and as a way to reduce acne. I would call it a positive experience since its main function was to reduce risk of pregnancy, and I did not become pregnant while using it. 
However, there are side effects (as with any oral contraceptive). Different pills use different kinds of synthetic hormones, each of which may or may not have a different effect on the user's skin.
Aubra is partly comprised of levonorgestrel, which is one of the most androgenic (acne causing) synthetic hormones used in oral contraceptives. 
I have been continually breaking out in cystic acne since I started Aubra half a year ago. I am currently in the process of switching to Ortho Tri-Cyclen (lower androgenicity)."
