Good looking skin is healthy skin. No cream, serum or lotion—no matter how high-end and effective—will matter all that much if the stuff you put inside your body is crap. A healthy, nutrient-rich diet is integral to your overall skincare regimen. The foods you should focus on are ones rich in vitamins, protein and essential fatty acids. But note: one salad today isn't going to clear your skin tomorrow. Eating for better skin is more of a lifestyle change, not a one-time fix. But if you put in the right fuel, you're going to start noticing a difference soon.
