This portable hot-steam and cool-mist facial steamer is lightweight and economical, yet it's loaded with professional features. Hot (steam, with or without ozone) and cold (cool-mist) functions can be used independently, or together; allowing for these five modes: Hot-steam only, hot-steam plus ozone, hot-steam plus cool-mist, hot-steam plus ozone and cool-mist, cool-mist only. The stainless-steel coil and 750-watts of heating power quickly produce muscle-relaxing, steam vapor. Suspended under the hot-steam Nozzle is a small metal cup designed to hold a cotton ball (or other material) scented with liquid aromatics or essential extracts. Steam can pass over the cotton, become infused and create an incredible aromatherapy experience. This machine also houses a long-life, germicidal ultraviolet bulb. This outputs disinfecting rays (commonly referred to as "ozone") that kill most micro-organisms and sterilize the steam as it passes through the unit. In addition, this unit features an internal ultrasonic humidifier which produces a fine fog or cool-mist.
