Not all products that are skin-care musts are found in bathroom drawers; some pop up in the kitchen. Although more extensive research needs to be done on the subject, many foods are strongly suspected of helping skin stay young and healthy looking.
It's a good idea to eat foods that are fresh and not overly processed -- try shopping around the edges of the grocery store and avoiding the aisles -- that's where the less healthy food typically lurks. A balanced mix of nutrients, vitamins, minerals and antioxidants should keep your skin vibrant. Biotin, a type of vitamin B, helps replenish skin, along with your hair and nails. Vitamin A is big when it comes to repairing damaged tissue and maintaining healthy skin. Vitamins C and E are examples of antioxidant powerhouses that box out free radicals and work to protect skin from the sun's fierce rays.
These sorts of good guys can be found in loads of fruits and veggies, as well as many other foods. The right kinds of protein are also important -- they help cells fix themselves when damaged. One study suggests that people who eat things like legumes, vegetables and olive oil, coupled with less sugary foods and dairy products, had less wrinkly skin in old age [source: Purba]. So find a good diet that makes your skin happy and stick to it.
