Mehmet Oz, MD, Cardiology, answeredIn nature, vitamin A (retinol) protects plants from UV-induced free-radical damage. In skin products, vitamin A is described as an antioxidant that protects the skin against photoaging by fortifying each cell against damage by exposure to free-radicals. In higher concentrations, vitamin A can act as a humectant, drawing water to the surface of the skin. Moreover, vitamin A (topical retinol) is described as improving fine wrinkles associated with aging. Thus, vitamin A actually treats the signs of aging or photoaging.
Consuming adequate amounts of vitamin A may improve the texture, moisture and elasticity of your skin. Vitamin A has an essential role in the development and maintenance of the skin. This vitamin has a pivotal role in the development and maintenance of the epithelial tissue -- the lining of eyes and skin. One of the main functions of the epithelial tissue is to serve as a barrier to bacteria. Low levels of Vitamin A can lead to a dry, flaky complexion. Vitamin A can be found in colorful fruits and vegetables. Therefore, increase your intake of carrots, spinach, kale, apricots and papaya.
Ways to increase your vitamin A by simply adding grated carrots to spaghetti sauce and salad greens or replace tomatoes with papaya in a homemade salsa.
Ellen Marmur, MD, Dermatology, answeredVitamin A is found in fish oil, salmon, carrots, dairy products, spinach, and broccoli. Since it promotes normal keratinization (the turnover of skin cells), it helps with conditions such as acne, eczema, and psoriasis. Without it, skin becomes extremely dry and dull. It's important to note that if you use a synthetic retinoid (a derivative of vitamin A) on your skin, you may need to stop vitamin A supplementation, since too much of this vitamin can lead to hair loss and liver dysfunction.
