Dr. Scholl's™ Blister Shield Plasters provide immediate relief from blister pain and help facilitate the healing process. Developed with best in class hydrocolloid technology, these large heel plasters seal the blistered area to protect it from bacteria and dirt, and stay in place for up to 7 days. They create a moist environment that supports healing, while the cushioning gel and strong adhesive keep the plaster securely on your heel. Waterproof and breathable, they are suitable for use in the shower and while swimming, making them ideal to prevent heel blisters or to cover blisters that have already formed. A handy pack that is perfect to keep in a first aid kit. Pack Contents 5 large heel plasters. Safety Warning For external use only. Avoid contact with eyes. Do not use if you are allergic to the dressing or its components. Do not use on broken skin, open or infected wounds. If you have a blister and have diabetes, poor blood circulation or loss of feeling in the feet, always seek guidance from a healthcare professional before self-treating, as you may be at risk of developing an ulcer. In case of any doubt consult a healthcare professional.
