Sheet-like face pack and kits for face packs

A kit for a face pack comprising an exothermic structure that comprises a pouched part having an air-permeable side and an air-impermeable side, a substrate layer for gel that is set on the outer surface of the air-impermeable side, and an exothermic composition that is put into the pouched part, and gel that is separate from the exothermic structure, wherein a moisture permeability of the air-permeable side is within the range of 300 to 2,300 g/m2·24 hours by the Lyssy method (JIS K 7129, at 40 degrees by Celsius temperature scale and relative humidity of 90%), and wherein within 10 minutes after preparing a gel layer by using the gel on the outer surface of the substrate layer, the temperature of the gel layer reaches 38 degrees by Celsius temperature scale (° C.) and is then maintained between 38° C. and 45° C. for 20 minutes or more, wherein the temperature of the gel layer is determined according to the method for determining a temperature based on JIS S 4100.
