What do you recommend as skin care?

I recently noticed that my skin got worse (as in before it was really nice, and now I have blackheads and enlarged pores... interesting facts about me :P), so I'm considering skin care. At the moment it's just sunscreen because I heard that prevents aging and also I've been to lazy to really get it in my routine... well, as you can tell, I have very small knowledge of the topic, so what (if possible cheap!) brands would you recommend for a cleaning lotion and skin cream? (If possible "world-wide" brands such as Bodyshop etc. as I'm in Europe... )
