Topical composition testing method and apparatus

Abstract

There is described a method of testing a topical composition, wherein the method comprises: providing an ex vivo tissue comprising a skin tissue layer and a muscle tissue layer, wherein at least one temperature probe is positioned on the surface of the skin tissue layer; adjusting the temperature of the ex vivo tissue such that the temperature at the surface of the skin tissue layer is 32-37° C.; applying the topical composition to the surface of the skin tissue layer, wherein the topical composition effects a decrease in temperature at the surface of the skin tissue layer; measuring the decrease in temperature at the surface of the skin tissue layer over time effected by the topical composition using the at least one temperature probe; and measuring a subsequent increase in temperature at the surface of the skin tissue layer over time using the at least one temperature probe.
