For aesthetic treatments with oxygen means the method of supplementation of oxygen to the body through the skin. This is a technique that enhances the transdermal delivery, in temporary way, the content of oxygen available at the epidermal level. The oxygen is delivered through special devices and handpieces: they generate a pressurized jet which, in contact with the skin, creates a depression skin. Such curvature surface results in a mechanical action of distension which widens the pores, increasing the permeability: it is thus possible the delivery, not only oxygen, but also of mixtures of active principles.
