Green Tea Compounds Protect Against Sunburn, Long-Term UV Damage

January 28, 2013: 12:00 AM EST
Compounds known as catechins, found in green tea and also available in supplements, are absorbed by the skin when taken orally and protect the skin from the damage caused by ultraviolet rays (UV), according to the British study. The results were based on tests involving 14 healthy human subjects (12 women) with fair skin who were given green tea catechin supplements and then exposed to UV rays. Researchers measured the level of sunburn (erythema) before and after supplementation. Catechin supplements given at doses similar to amounts available in about two cups (500 ml) of green tea protected the skin from sunburn as well as long-term damage.
