I am on Deppo, and I am 25, and I feel like a pre-teen all over again. Different b.c. act in different ways. Yasmin and Ortho Evra did not cause me to break out. I believe it has to do with hormones. Specifically the control of the male hormone. It is called androgen. Some b.c., I beleive contain this hormone, or do not control it. I beleive I read that the hormones higher in progestrine and estrogen do that. Desogen, Demulen, Brevicon, Ortho Tri-Cyclen, Ovcon 35, Ortho Novum 7/7/7 and Nelova are likely reducers or acne and are often perscrided for it. You can do an internet search for 'birth control and acne', Hope it helps!
