Technologically advanced healing means your blister cushion stays on better and your injury improves faster. That’s optimal healing. So for the ultimate in blister protection, try these bandages that stay on for several days, even through handwashing and showers. You're welcome to wear them until they begin to come off on their own. And while they’re on, they’ll show you they’re working: within 24 hours of application, the product will begin to swell and a white bubble will form to indicate the healing process has begun.
