Carotenes and lycopene

When beta-carotene is ingested, it is transformed into vitamin A to suit the needs of the body, which is why hypervitaminosis is never caused by its consumption. Beta-carotene circulates in the blood without undergoing changes and is then stored in the fatty and cutaneous tissues of the body, where it acts as a skin pigment. Beta-carotene is essential to achieve a faster and more intense tan. 
Lycopene, as an antioxidant, synergizes the properties of carotene; therefore, both contribute to maintaining healthy skin, avoiding erythema (redness) and the harmful effects of ultraviolet rays.
