I just got back from Thailand where I tried a fish spa for the first time. Basically you put your feet in a tank full of little fish which then gently suck/nibble off all the dead, flakey skin leaving your feet silky smooth. My feet are hyper ticklish so the first couple of minutes were almost unbearable but it was OK after 20 mins. More like pins and needles really. Anyway, if you get the chance to try it I can highly recommend. The fish like it too!
