The fish pedicure is a unique beauty treatment that involves submerged feet in a tank filled with tiny fish that nibble away at dead skin cells. While there are benefits, including smooth exfoliation and pain relief, potential risks such as allergic reactions, infections, and accidental injury should be considered. The science behind fish pedicures lies in the evolutionary adaptation of their tiny mouths to eat dead skin cells from other fish, making them effective for human dermal skin care. Ultimately, individuals must weigh these factors to decide if a fish pedicure is right for them.
