Carrots are good for the skin because of their high vitamin A and beta-carotene concentrations, which have several benefits for the skin including acting as natural sun protection. Here's how it works:
The Benefits of Vitamin A and Beta-Carotene
Beta-carotene is a form of provitamin A that’s converted into vitamin A by the body as a product of metabolism. Because beta-carotene is water soluble, the body converts what it needs from plant sources and excretes any excess. Numerous studies have shown that dietary beta-carotene is effective against ultraviolet radiation damage. The journal Photochemistry and Photobiology reports that 10 weeks of beta-carotene supplementation provides an SPF of 4 and that every additional month of supplementation increases protection.
Additionally, numerous studies have concluded that dietary and vitamin A supplementation is effective as a treatment against chronic hand eczema. The British Journal of Dermatology reports that a medication made from condensed vitamin A named alitretinoin, which is normally used to treat skin lesions, also cures chronic hand eczema. Dermatologic Surgery reports that vitamin A supplementation is effective in reducing tumors in patients with nonmelanoma skin cancer.
Too Much of a Good Thing?
But before you go crazy for carrots, know that it's possible to have too much a good thing. There are popular stories about people’s skin turning orange from eating too many carrots and many people wonder if the stories are true. They are, and the International Journal of Food Sciences and Nutrition reports that overindulgence can turn your skin and the whites of your eyes to tints of orange and yellow, a condition called hypercarotenemia. Researchers determined that ingesting 20 milligrams of beta-carotene per day, which is the equivalent of three 8-inch carrots, is sufficient to pose a risk.
