ABSTRACT:
Skin treatment solutions are applied to the face, for example, by use of a flexible opaque mask 10. On a timed basis, one or more treatment solutions from vials 24-26 are provided to various facial areas via flexible tubes 20. In order to enable use of active treatment solutions including vitamin formulations subject to oxidation degradation in the presence of air, for example, a neutral atmosphere is provided. This is accomplished by supplying a neutral gas, such as nitrogen, from a cylinder 50 to mask 10 via flexible tubes 48. The neutral gas is infused between the mask 10 and the underlying skin at a low over pressure sufficient to drive air out from under the mask. Single treatment quantities of treatment solutions can be intermittently applied on a timed basis by the action of pump 36 operating under the control of programmable timers 30 and 40.
