Beta-carotene, found in fruits and vegetables, can prevent heart disease, eye problems, arthritis, and skin problems. It can also protect against sunburn and UV light, treat pigmentation disorders, and reduce the risk of some types of skin cancer. It is generally safe, but high doses can cause skin discolorations.
Contained in many fruits and vegetables, beta-carotene can provide many of the dietary requirements for vitamin A. It can prevent conditions such as heart disease, eye problems, arthritis, and even skin problems. The substance is a pigment called a carotenoid and is usually red, yellow, or orange; Yellow-orange and green vegetables are often sources of beta-carotene, while supplements are often available as well. While used for a number of health reasons, beta-carotene in the skin can help protect against sunburn and ultraviolet (UV) light, as well as treat pigmentation-related disorders.
In studies, the effects of beta carotene on the skin have been found to heal it after exposure to UV light. Redness from sunburn can be reduced, and scientists believe the pigment may help repair tissue at the genetic level by reducing damage to deoxyribonucleic acid (DNA). For some people with certain skin disorders, it also helps prevent sunburn. Researchers have found that many sun-sensitive people can often stay outside longer than is possible with the help of beta-carotene; However, large amounts are usually required to have such an effect.
Beta carotene in the skin can be combined with vitamin E, lycopene, and selenium; Researchers have discovered that this blend may offer even more protection against ultraviolet light. Whether the carotenoid is taken alone or with other supplements, studies have found that sunscreens are generally much more effective at protecting skin from sun damage. Researchers often recommend using a suntan lotion in addition to applying beta carotene to the skin. Sometimes the substance is taken orally, but to protect the skin, it usually has to be taken for several weeks.
Pigmentation disorders are often alleviated, such as melasma, a condition that typically results in dark discolorations on the face. Beta-carotene in the skin can fade abnormal pigmentation, studies show, while returning some people to normal coloration. It may also reduce the risk of some types of skin cancer in men, although research has not shown that these problems are prevented. Other skin ailments, such as psoriasis and vitiligo, a pigmentation disorder, are sometimes treated with beta-carotene.
In addition to use on the skin, the pigment can also be used to treat other health problems. It is sometimes used for macular degeneration in the eyes, arthritis, and promotes better health in the elderly. Pregnant women often benefit from taking it as well. Beta-carotene is generally safe, but high doses can cause yellow or orange skin discolorations.
