A hand scrub is a treatment in which the hands 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 gripping and holding all day long, and soothe tired muscles. One of the main benefits of receiving a hand scrub is the built-in massage. Allow Zen Den Therapists to scrub your hands 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 hands and muscles.
