Compeed Blister Plasters use Hydrocolloid Technology. This forms a second skin that keeps the blister moist and speeds up healing, while preventing infection from bacteria. The deep cushioning pads for blisters help prevent painful rubbing, common with heel, foot and toe blisters that sit close to shoes or clothes. Unlike regular plasters, tape or medical dressing, Compeed Blister Plasters use special adhesive and tapered edges to help stick tight in place without rubbing off. They are also breathable & waterproof. This mixed pack contains 10 assorted plasters, great for treating blisters on the heel, foot, or other areas. They are also individually wrapped, making them great for use on the go. 95% of users agreed that Compeed provides instant pain relief*
