When it comes to your skin, beauty is more than skin-deep. What you eat has a lot to do with the appearance of your complexion, and a number of skin problems, such as acne, can be cleared up simply by altering your diet.
As a general rule, a diet high in fresh vegetables, which are rich in bioflavanoids, and plenty of omega-3 fat will lay the necessary groundwork for a healthy, youthful complexion. Certain nutrients also have protective benefits, helping you ward off the damage caused by exposure to the elements.
Do remember, however, that loading up on certain skin-clearing foods while still eating some of the most damaging will likely not make a significant impact.
Collagen breakdown can leave your skin saggy, and vitamin C can help tighten it back up.
