If you really want to exfoliate, you'll travel to Turkey to have your dead skin nibbled on by doctor fish (that's a species of fish, not the name of a dermatologist).
Lucy Atkins reports in today's Guardian that the so-called "psoriasis fish cure" is quickly becoming popular among Europeans and Japanese, who are willing to travel to a remote, saltwater lake in Anatolia and offer their epidermises up as a feast for the local fishes. One brave soul described the treatment this way:
"I stayed in the pool for about 15 minutes, as long as I could bear, and the fish - about 500 minnow-sized feeders - continued to flock to my feet. It felt like a cross between tweezers and suction cups pecking at me and tickled to the point where I had to pull them out several times."
A rigorous Google search turned up no spas in Los Angeles or New York which offer the treatment. And you know it'll hit L.A. before it hits anywhere else in the country.
