2. Load up on Vitamins A, C & E – A diet rich in vitamins A, C, and E is widely considered to contribute to a younger-looking skin. Vitamin C plays a critical role in collagen production. [2] Vitamin E is a potent antioxidant that scours out free radicals, which cause wrinkles and skin sagging. Vitamin A has been proven to improve skin’s elasticity and encourage the production of skin-building compounds, thus being a popular ingredient in many anti-wrinkle creams nowadays. [3] If you fill your diet with foods that are high in these vitamins, then you skin will surely get the best “internal pampering” out there. Buy grapefruits, oranges and berries, and make it a goal to include oily fishes in your meals at least thrice a week. A healthy diet means a healthy skin – pure and simple.
