More and more people realize how important it is for healthy skin  to not only protect it externally but to nourish it  with vitamins and minerals internally. Various synthetic vitamin A derivatives have long been used to treat skin diseases, but there’s been a lot of mystery around what vitamin A does exactly.  

American researchers have recently discovered a protein called RELMα, which has strong antibacterial effects in the skin and vitamin A activates it . They successfully proved on animal models that the animals whose diet didn’t include vitamin A produced none of this important protein.  

Skin is our largest organ, and it needs sustained protection against pathogens. If the immune system doesn’t get the nutrients it needs, it cannot serve its functions and various infections may develop . Vitamin A nourishes skin from the inside, so  everybody who wants to reduce the risk of skin problems should take it.
