Dr. Mehmet Oz, MD, Cardiology (Cardiovascular Disease), 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.
Dr 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.
