  • Facial patch
    Patent number: 11311423
    Abstract: Provided is a facial patch including a support, a pressure-sensitive adhesive layer, and a release layer in this order, in which (a) the pressure-sensitive adhesive layer satisfies the following conditions (a-1) to (a-3): (a-1) the pressure-sensitive adhesive layer contains a styrene-isoprene-styrene block copolymer, a tackifier resin, and a softening agent; (a-2) the ratio (mass ratio) of the styrene-isoprene-styrene block copolymer and the tackifier resin is 1:2 to 1:4; and (a-3) the content of the softening agent is 40% to 60% by mass; and (b) the support has elastic moduli with a Young's modulus of 0.01 GPa to 0.5 GPa, and also provided is a method for producing the facial patch, the method including a step of forming a pressure-sensitive adhesive layer on the upper surface of the release layer.
