It works like this: The infrared heater warms up your body at the core rather than on the skin’s surface. Solocarbon is the only infrared heater shown to lower blood pressure, increase core temperature and aid in weight loss. Traditional saunas use steam to heat things up, which can get pretty uncomfortable for longer periods of time. Plus, you can’t move it – it stays in the same spot every day. The best part about the Solo? It is the ONLY portable sauna to feature built-in chromotherapy lighting. An LED array provides the ancient healing method of light and color therapy to improve health and harmony. Includes a mini facial (cleanse, exfoliate, massage, and a collagen mask).
