Firm and Bright
You’re probably up to your eyebrows (Botoxed or not) with hearing “eat more fruits and vegetables.” But if you have yet to take that advice to heart, maybe knowing that they prevent wrinkles will do the trick. The colorful pigments that produce bright orange and red also refill antioxidant levels in your skin.

The skin doc’s 3 top picks: SWEET POTATOES, TOMATOES, CANTALOUPE

What they do: Replenish your skin’s supply of antioxidants, so they're ready to scarf up free radicals whenever they make an appearance. Free rads are highly reactive oxygen molecules that damage cells and contribute to just about everything that can go wrong with skin, from dryness to crinkles.

Fresh and Juicy
Your body can’t store much wrinkle-fighting vitamin C, so you need to keep your supplies stocked. The easiest, simplest way: Have some citrus every day.

The skin doc’s 4 top picks: ORANGES, LEMONS, LIMES, GRAPEFRUIT

Actually, ounce for ounce, oranges are the top citrus C source but you can only eat so many, right? For variety, make lemonade, squeeze limes on melon, add grapefruit to salad, and instead of drinking soda, fizz up OJ with sparkling water. It all adds up.

What they do: Keep skin’s vitamin C levels high. While C’s a nifty antioxidant, that’s not the key reason it’s here. It helps keeps collagen -- the supportive protein fibers that stop skin from sagging -- strong and resilient. (Flimsy collagen means lines and wrinkles.) Since collagen breakdown really picks up in your mid-30s, eat citrus early and often to head off aging.
