Scholl Blister Shield Plasters are an advanced Blister protection plaster utilising a revolutionary dual layer Hydra-GelTM Technology. The hard outer shield protects and guards the formed blister from friction and rubbing. The soft gel island provides advanced cushioning and keeps the blister hydrated and flexible. They offer instant relief, invisible cushioning and stay firmly in place, whilst also being waterproof. Scholl Blister Shield Plasters can also be used to prevent blisters. Directions: Ensure skin is clean, dry and free from creams and oils. Remove backing film 1 and place plaster (adhesive side down) centrally over the blister. Remove backing film 2 using the blue tab & gently smooth down adhesive edge to skin. Leave plaster on until it falls off naturally. To remove, slowly stretch the plaster along the skin.
