Beta Carotene & Healthy Skin

Beta-carotene is a provitamin A carotenoid, one of two sources of vitamin A. Vitamin A is not only important to your overall health and immunity, but also to the integrity of your organs, including your skin. In the body, beta-carotene converts to retinol and other forms of vitamin A. Retinols work actively within the body and have been used in topical skin treatments since the 1970s.
