8 Surprising Habits That Make You Look Older
The habit: Drinking mango-pineapple smoothies.
Why it's making you look older: We know what you're thinking: Fresh fruits and vegetables are supposed to be packed with antioxidants that fight the free radicals that damage skin cells. And they sure are, Bowe says, but juices that contain lots of fruit—and only fruit—tend to have sky-high levels of fructose. Even though fructose is a natural sugar, it can still lead to the glycation process (again!), which makes your skin look weary.
The fix: Throw some kale into your blender. Bowe says that dark green, leafy greens have the highest amounts of those skin-saving antioxidants—including zinc, which helps to break down old collagen, build new collagen and prevent wrinkle formation.
