Other than using sunscreen every day, what are some other ways to keep my skin from aging anymore than it already will?

Diet ; Lifestyle: I recommend the paleo diet as it is high in veggies, moderate in fruit sugars, high in protein, vitamins, minerals, other nutrients. Has an anti inflammatory effect along with many other health redeming qualities. Drink lots of water. Avoid processed food and drink. Avoid sun bathing, smoking. Exercise and stress reduction as well.
