I'm 31 and wear SPF 30 on my face daily - but since I've started on Yasmin the sun spots seem to be getting worse daily (I thought this wasn't supposed to happen until my 40's).

Its not exclusive to Yasmin as it can happen with any hormonal form of birth control. It happens when your body gets an increase in hormones - either pregnancy, hormonal birth control, or hormone replacement therapy http://www.medications.com/effect/view/42117?item=21517
