Hi I am experiencing a similar issue. I have dark skin so I do not get burnt but I do get very dark even though i wear sunblock and don't spend much time in the sun. I do get more rashes now that it is summer. I have decided to go off the pill so I hope the damage is reversible. I have been on the pill for about a year as well.
I've been on Yasmin for 2 years now. I have very fair skin which I know burns so I use sunscreen. This past week I went to the beach in Florida and was out in the sun not more than 3 hours and got burned even though I was wearing SPF 50! My face got burnt and for the first time my forehead and eye area is all swollen up because of it. I've had worse sunburns on my face before and have never had this happen. After reading your post I'm wondering if this is a side effect of Yasmin also. I didn't gain weight on it until this year but that's probably because of other reasons. It does really kill your sex drive! Although I can't complain about the now acne free skin and super short periods.
