Undecided Question

Help! I'm 16 and I'm getting fine lines around my eyes! What can I do?

Just like it says in the header, I'm only 16 and I'm already starting to get fine lines around my eyes. I try to take good care of my skin, but I'm VERY fair skinned, so total UV protection can be difficult. Is there anything I can do about these lines? How can I prevent them from getting worse? Thanks!
