Antioxidant-packed green tea holds promise in treating inflammatory skin conditions such dandruff, lupus-induced lesions and psoriasis, according to a new study.

In a study to be published in the Aug. 18 edition of Experimental Dermatology, scientists divided mice with a genetic predisposition for psoriasis into two groups — one was bathed routinely in warm water and one in a green tea extract mixed with water, according to a report in British Columbia's CDC News.

The mice bathed in the green tea extract developed skin lesions much later than the mice cleaned simply with warm water. The green tea group also had lesions that were smaller and less inflamed.

Scientists said the tea slowed the production of skin cells by regulating the activity of caspase 14 which is involved regulating in a skin cell's life cycle.

The study is important especially for dandruff sufferers, said the scientists, because many dandruff-fighting shampoos contain carcinogens and long-term use may be unhealthy.
