ABSTRACT:
The present invention provides a method of sustaining the rate of heat felt on the skin as a result of an exothermic reaction between a combination of an unencapsulated and an encapsulated catalase, and peroxide. The catalase component provides a sustained heat release and in combination with other non-catalase heat-generating agents, the rate of heat released and felt on the skin can be further controlled. The compositions of the present invention also soften the skin and contribute to the health of the skin by reducing the presence of oxygen free radicals on the skin surface.
