The included two mask sizes allow this product to serve the dual purposes of hot steam inhalation therapy and facial beauty treatments. Steam inhalation therapy is a natural means for helping to relieve the congestion of bronchitis, the common cold, allergies and a variety of other respiratory and sinus ailments. Steam inhalation opens up congested sinuses and lung passages, allowing you to discharge mucus, breathe more easily and heal faster. Steam facials open the pores of the skin, helping to naturally remove dirt and residue build-up without the use of harsh soaps and chemicals.
