How long can polycystic ovarian syndrome last?

I was diagnosed with polycystic ovarian syndrome at the age of 27. I've just turned 33 and still continue to have acne breakouts even though I take the pill, Yasmin on a regular basis. I never had acne until I was 27 and soon found out I had poly cystic ovarian syndrome. How long can this condition last, am I doomed to have acne and poly cystic ovarian syndrome until my cycle ends sometime in my 50's?
