Red or yellow bell peppers

While all vegetables are good for your skin, yellow bell peppers are particularly healthy due to their high vitamin C concentration. 569% of your daily value is found in just one yellow bell pepper. Women who ate a lot of yellow vegetables had fewer wrinkles than women who didn't eat them, according to a study published in 2010.

Bell peppers, like sweet potatoes, are high in beta carotene, which your body converts to vitamin A. One cup (149 grams) of chopped red bell pepper provides 156% of the daily value for vitamin A. They're also high in vitamin C, making them one of the greatest sources. This vitamin is required for the production of collagen, a protein that maintains skin firm and strong. A single cup of bell pepper (149 grams) has 211% of the daily value for vitamin C. Vitamin C also has antioxidant properties, which means that consuming it can help you get the most out of your sunscreens, decrease wrinkles, and prevent dry skin. A large observational study of women found that eating a lot of vitamin C reduced the risk of wrinkled and dry skin as they got older.
