Aesthetic use
Commercially, treatment by Doctorfish has expanded outside the realm of skin disorders
into the general spa industry, being very popular as a pedicure treatment in the removal of
calluses from feet. Fish pedicures can be found in dozens of countries (section 5), and are in
high demand. Within two years of the first fish pedicure in the United Kingdom, nearly 300
salons across the country were offering the service (Wallop 2012).
