Body wraps were originally a treatment where elastic bandages or plastic wrap was tightly wrapped around the body to cause quick weight loss through vasodilatation. You can still find these types of "slimming" body wraps, which result in the temporary loss of weight and inches, at some spas.
But today a body wrap in a spa is more likely to be treatment where – sometimes following an exfoliation through dry brushing or a salt scrub - you’re slathered with a body mask made of algae, seaweed, mud, clay, lotion or cream, then wrapped for 20 minutes to keep you warm. This body wrap treatment is sometimes called a body cocoon or body mask. Then you might either jump in a shower or the therapist will rinse you off with a handheld shower or a special Vichy shower that feels absolutely fabulous. The body wrap usually ends with an application of lotion (technically not a massage).
Body wraps that use algae, seaweed, mud or clay are detoxicating treatments that help rid the body of toxins through metabolic stimulation. Body wraps using shea butter and rich lotions are hydrating treatments geared towards softening the skin.
