One of the latest fads in skin care involves tanks of live fish, and it's stirring up quite a controversy. Garra rufa, or doctor fish as they're known to most of the world, have been used in spas across Europe and Asia for quite some time, but they weren't introduced to the United States until 2008. That's when a Virginia salon owner brought the fish home from a China spa and started offering doctor fish pedicures . The fish originate in Turkey, where they've been used for more than 100 years to treat serious skin conditions such as psoriasis. The water temperatures there are high, which prevents many nutrients from surviving. As a result, doctor fish are basically starving and seem to have an insatiable appetite for dead skin . The popularity of doctor fish pedicures in the United States probably has as much to do with novelty as anything else. At the very least it's a creative way to exfoliate, and it seems to work. Long before doctor fish were giving people pedicures in the United States, they were being used around the world to treat serious skin conditions, such as psoriasis and eczema. A spa in Turkey has been offering this service for more than 100 years, and in 1988 it became an official treatment center for people who have psoriasis. It now treats about 3,000 patients every year from all over the world . Psoriasis and other similar skin conditions cause a buildup of dead skin cells that form scaly patches on the skin, which can be uncomfortable and unsightly. Doctor fish help treat these conditions exactly the same way they help prepare feet for a pedicure, by eating away at dead skin. Soaking in water helps soften the scaly patches, and that in turn allows the fish to dig in. Completely clear skin, however, will take a commitment, since doctor fish can offer only temporary relief . A recent study backed up these claims. Not only can doctor fish be an effective treatment for psoriasis when combined with controlled ultraviolet therapy, but they can also help make symptoms less severe when they return. Patients involved in the study averaged more than eight months of psoriasis-free skin, and few had adverse affects. Nearly 90 percent said they preferred doctor fish treatment to other forms of therapy . To say the least, the results of the study are promising for those who suffer from psoriasis.
