Which vitamin helps to maintain healthy skin and mucous membranes?

Vitamin A plays a crucial role in maintaining healthy skin and mucous membranes. It is essential for the growth and repair of epithelial tissues, which are the thin layers of cells that make up the outer surface of the skin and line various cavities and organs. This vitamin contributes to the integrity of these tissues by promoting cellular differentiation and growth, helping to prevent dryness and maintain optimal skin health.

Additionally, Vitamin A is involved in the production of sebum, which is the oil that keeps skin moisturized. Its antioxidant properties also help protect skin cells from damage caused by free radicals, supporting overall skin health.

While other vitamins, such as Vitamin C, Vitamin K, and Vitamin B3, also contribute to skin health in various ways, it is Vitamin A that is specifically recognized for its critical function in the health and maintenance of skin and mucosal membranes.
