ABSTRACT:
A mixture of air and steam is provided for facial treatment through a flexible hose at a temperature range controlled by the effective size of air vents. The interior of the apparatus as well as that of a boiler located in the housing is pressurized when a fan is activated. A one-way valve associated with the boiler permits fluid communication to the interior of the boiler only when the pressure or steam in the boiler is not sufficient to block incoming fluid.
