The 5 Best Anti-Aging Tips We've Ever Heard

You know that refined carbohydrates and added sugars are at the top of every nutritionists don't-eat list, but dermatologists avoid them too. They can lead to wrinkles through a process called glycation—eating refined carbs and sugars creates a quick spike in blood sugar, and when those sugar molecules link up with the collagen in your body (which normally gives skin its elasticity), it leads to stiffness in your skin, says Whitney Bowe, MD, clinical assistant professor of dermatology at Mount Sinai Medical Center in New York City.

Eat more of these instead: Healthy fats like omega-3 fatty acids, and colorful fruits and vegetables. The fats can help lower inflammation, says Bowe, which calms redness-inducing issues like acne and rosacea, while people who ate a lot of colorful produce were judged as looking healthier and more attractive in a PLOS One study.
