10 Almost Unbelievable Secrets To Eternal Youth

One of the biggest culprits of skin aging is dryness — when your skin lacks moisture, it doesn't look as plump. Besides the "no duh" advice of drinking more water, make sure to also hydrate your skin on the outside with hyper-moisturizing ingredients. Hyaluronic acid occurs naturally in the body, but levels decrease as we age, which hinders the skin’s ability to retain moisture and leads to wrinkles. Products containing this super-hydrating ingredient boost skin’s elasticity and hydration, as well as helps the skin’s surface appear smoother.

Many impressive foods, besides being delicious, can also keep you healthy for the long haul. "Blueberries are a great place to start," says Dr. Frank Lipman, integrative and functional medicine physician and founder of Eleven Eleven Wellness Center. "They provide one of the most concentrated sources of flavonoids, a class of polyphenols, which may help improve vision, memory, and concentration, and also slow down aging. They also contain other polyphenols that have been shown to have anti-bacterial qualities and tannins, which reduce inflammation in the digestive system. Blueberries also have a high fiber content, and much of that fiber is pectin, which is soluble and helps lower cholesterol levels." Another great anti-aging ingredient? Antioxidants, which you can get through a wide variety of fruits and vegetables. Of course, there are heavy-hitters like dark, leafy greens, but according to nutritionist Lauren Schmitt, those aren't your only option for adding a free-radical fighter into your diet. “I always tell people not to worry so much about a specific color, but be concerned about getting a rainbow of colors. Even light-colored cauliflower has antioxidants that are different from what you’ll get in other vegetables," she says. (Ammiel Mendoza)

It seems like a no-brainer, but so many women still don't protect their skin from the sun. UVA stands for aging rays, people — you can't get any more obvious than that. “You have to use a sunscreen that protects against UVA and UVB rays every day, and the more you use, the better,” says Dr. Jay Kulkin. While this won’t help your preexisting problems, it will prevent further premature signs of aging — and you know what they say about the best offense. Try: Cetaphil Daily Facial Moisturizer UVA/UVB Defense SPF 50, Yes to Cucumbers Daily Calming Moisturizer with SPF 30, Clinique Sun Broad Spectrum SPF 45 Sunscreen Targeted Protection Stick.
