"Incorporating sweet potatoes into your diet can help you achieve wrinkle-free skin," says Drayer. The reason: This super-nutritious vegetable is loaded with beauty-enhancing beta-carotene, a powerful antioxidant that may protect skin from the damage caused by sun exposure. Our body also converts beta-carotene to vitamin A, which helps keep skin smooth.
