A body wrap is a relaxing spa and beauty treatment where your skin is cleansed and then coated with a therapeutic mask, such as seaweed, algae, clay, mud, herbal or mineral-based products, before you are wrapped snugly in film, bandages, towels or a warmed thermal blanket. You rest for around 20 to 40 minutes while the ingredients work on the skin and the warmth encourages you to relax. Wraps are offered for different reasons: hydrating and softening the skin, cleansing, easing tired muscles, or as a firming and toning treatment.
