High Maintenance Salt Scrub is the best yet! Our special blend of sea salt, essential and carrier oils will leave those rough areas smooth and silky. Benefits: Salt scrubs are used for exfoliation and detoxification. The use of sea salts are a must. Our skin is comprised of many layers, and the top layer or dead layer is a combination of debris from days gone by. Even though showers and baths wash away some of it, the remainder of the layer must be removed with an abrasive material such as a scrub.
