Blister Bandages Hydrocolloid Waterproof & Invisible Foot & Toe Blister Cure 44x69mm

A blister is an area of raised skin with liquid inside, acting as the body's natural protection against pressure and friction. When high degrees of friction occur, the outer layer of skin (epidermis) separates from the layers beneath, allowing fluid to fill the space. This cushions the wound from further injury and prevents infection.

Blisters on the heels, feet, and fingers are highly common. To prevent them, it is essential to reduce friction. Properly fitting shoes and keeping feet dry are key measures in blister prevention.
