The best course of action is to protect the blister in order to keep it from tearing and allow the skin under it to heal on its own. Eliminating or reducing the source of friction is necessary for a blister to heal properly. Using a Compeed® Blister plaster will help you by relieving pain instantly, providing deep cushioning, reducing pressure and creating a moist environment, thus optimizing the time for the blister to heal under this protective second skin.
