The lastest wonder ingredient making the rounds in the skin-care community, coffee cherry, is being touted as the ultimate antioxidant. The extract from the berry has been clinically proven to have "one and a half times more antioxidants than green tea," says Ranella Hirsch, M.D., a dermatologist in Boston. This means it can more effectively ward off free radicals responsible for accelerating DNA damage that leads to skin's premature aging. In addition, it improves roughness and dryness. Find the extract in the RevaléSkin line (facial cleanser, day cream with SPF 15, and night cream, $40 to $110; available from your dermatologist).
