Best creams that help treat and prevent sun damage and wrinkles?

I am a 25 year old female who spends allot of time surfing in the strong florida sun, i do everything i can to prevent sun damage including applying a high SPF sunscreen many times a day and wearing a hat and long-sleeve rash guard, but i still find myself squinting allot and the salt dries my face. I have discovered my first wrinkle right between my eyes, and have dark spots starting to appear on my cheeks. Any advice on a good cream or home made recipe? Thanks!
