A method of and apparatus for applying at least one active substance to the skin simultaneously with the production of a cryogenic treatment effect. A liquefied refrigerant gas is released from a pressurized aerosol-type container simultaneously with or in sequence with the application of an active substance. The impregnated absorbent pad is then applied to the skin with the refrigerant gas evaporating slowly to produce the desired cryogenic effect while leaving a film of the active substance on the skin. The absorbent element may be provided on an applicator which itself may be mountable to the pressurized container to act as a control for the container and also to permit the directing of the stream of liquefied gas from a valve at the container outlet to either the active or to the reverse surface of the absorbent pad. The container may be carried by a base which also comprises a reserve of absorbent pads. The applicator can hold the absorbent pad in a required configuration such as a domed configuration.
A method of applying at least one active substance to the cutaneous covering to produce a cryogenic treatment effect, said method comprising storing at least one liquefied refrigerant gas in a pressurised container, impregnating an absorbent element by releasing a jet of liquid refrigerant from said container, said absorbent element also being impregnated with the said at least one active substance, subsequently applying said impregnated absorbent element to the cutaneous covering to be treated, and allowing said at least one refrigerant gas to evaporate slowly to produce the desired cryogenic effect and to leave a film of the said at least one active subtance on said cutaneous covering.
