Beta-carotene is a provitamin A, whose main sources are red, yellow, orange and dark green vegetables and fruits. The absorption of beta-carotene from food is about 5%, while the absorption from dietary supplements may reach up to 70%. This ingredient neutralizes free radicals and protects skin from the harmful effects of UVA radiation.
There is a relation with the decrease in cancer cases in people who used the diet rich in carotenoids. Beta-carotene shows also an ability to be stored in the skin and thanks to that it improves its colour as well as deepens tan and enhances its longevity.
