A foot scrub is a treatment in which the feet are exfoliated with soap and rocks. The purpose of this process is to remove dead skin cells, reduce calluses, improve circulation, relieve muscle tension from standing or walking all day long, and soothe tired muscles. One of the main benefits of receiving a foot scrub is the built-in massage. Allow Zen Den Therapists to scrub your feet with a special concoction of moisturizing oils and exfoliants which offers its own kind of massage and helps to relieve stress and relax sore, tired feet and muscles.
