Your diet is an essential part of how you look (inside and outside), so it should be no surprise that what you eat has incredible power over your skin! For example, eating too little protein could result in fine lines and wrinkles because this nutrient helps maintain elasticity, while not getting enough zinc could lead to dark under-eye circles! Eating foods with antioxidants is also great because they help combat free radicals that can damage your skin, leading to wrinkles and age spots.
