Green tea catechins found to benefit skin following UV damage
Scientists from the UK have discovered that green tea compounds called catechins may help protect the skin against sunburn and the long-term effects of UV damage. The study was performed on 14 healthy human subjects with fair skin and involved taking green tea catechin supplements for 12 weeks. The dose was roughly equivalent to two cups of green tea. The effects of the supplements were tested before and after supplementation by exposing buttock skin to UV rays and quantifying the level of sunburn. The results demonstrate that catechins may contribute to skin protection against sunburn inflammation and potentially longer-term damage caused by UV rays, and may therefore be a complement for sunscreen.
