9. Dark Leafy Greens
Greens like spinach, kale, collard greens, and rainbow chard are known for carrying all sorts of nutrients — including that oh-so-desirable vitamin C. But the nutrient that makes these veggies green is just as important to keeping your skin healthy. Chlorophyll, the source of the pigment, may increase the amount of procollagen (the precursor to collagen).
10. Chicken
Like beef and fish, chicken has all of the animo acids required to make collagen. In general, if you’re a meat eater who eats a balanced plate of protein and vegetables, you’re probably giving your skin a good dose of what it needs to stay as smooth as possible.
