If your going on Ortho-Tri for acne make sure it isnt Ortho-LO. I was put on that at the beginning of the year and i've had the worst time clearing up my acne since then. I went to my derm a couple weeks ago and he said that he has had a lot of patients on Ortho-LO and b/c of the horomones being so low, it auctually causes you to have more acne. Im starting Ortho-Novum this week and ready for clear skin again!
