Dr Scholl Large Bubble Dressing is ideal for preventing heel blisters or covering already formed blisters for comfort and healing. - PROTECTION: Scholl large blister dressings seal the blistered area, protecting it from bacteria and dirt. They also prevent shoes that may be ill-fitting from causing repetitive friction and pressure. In particular, the delicate layer of skin on top of the blister will be protected until it is ready to drain on its own. - PAIN RELIEF: Sores where shoes may be rubbing or blisters that have already formed due to prolonged walking can be treated with a Scholl dressing to provide immediate pain relief. - EASY TO APPLY: Simply wash the area to be treated and dry well. Remove the back of the dressing without touching the underlying adhesive and center it over the blister. Gently smooth the dressing so that there are no creases and the blister is sealed. The adhesive will keep the gel pad in place. - WATERPROOF: Scholl Blister dressings are 100% waterproof, so you can continue showering or swimming. Each patch is hydrocolloid and can stay securely in place for up to 7 days or until the edges begin to lift. - BREATHABLE: Dressings are designed to let the treated area breathe, in order to promote the healing process.- HEALING: Blister dressings create a moist environment that helps the wound heal faster than if it is not covered. Practical packaging - Each package contains 5 large, lightweight and easy to carry heel pads
