When it comes to having flawless skin, these common nutrients pack a powerful punch, and although more research needs to be done, there is some evidence the following nutrients benefit the skin:

Vitamin E
Best for healing sunburns and minimizing scars:
Whole grains, such as wheat and oats, have an abundance of this hard-working vitamin that maintains a lot of your body's tissues, like the ones found in your skin. Other foods rich in Vitamin E include wheat germ, leafy green vegetables, oily fish such as sardines or mackerel, and nuts. 

Olive Oil
Best for fighting blemishes and getting even tones:  Olive oil is an antioxidant rich food. The polyphenols and phytonutrients found in olive oil are especially valuable as antioxidants, which help to keep skin looking even-toned and blemish free.

Selenium

Best for protecting the skin from UV rays:
An antioxidant mineral responsible for tissue elasticity, selenium also helps prevent cell damage caused by free radicals. It may also play an important role in preventing skin cancer, as it can protect the skin from damage due to excessive ultraviolet light. Dietary sources of selenium include seafood such as tuna and salmon, garlic, Brazil nuts, eggs, and brown rice.

Vitamin A
Best for skin repair:
Rich sources of Vitamin A include eggs, milk, carrots, apricots, nectarines, sweet potatoes and spinach. It's best to consume Vitamin A from natural food sources as it can be harmful if taken in excessive amounts in supplement form.

Vitamin C
Best for preventing wrinkles:
Acting as a powerful antioxidant, Vitamin C has a proven ability to neutralize damage to skin cells caused by free radicals. Foods rich in Vitamin C include citrus fruits like oranges, strawberries, broccoli and cabbage.
