<p>A sheet-like face pack and kits for face packs are provided. The pack 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, a gel layer that is set on the substrate layer, and an exothermic composition that is put into the pouched part, wherein a moisture permeability of the air-permeable side is within the range of 300 to 2,300 g/m 2 . 24hours by the Lyssy method, and wherein the temperature of the gel layer reaches 38 °C within 10 minutes after the exothermic composition starts to contact oxygen 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.</p> |
