Blisters
A blister or bulla is a defense mechanism of the human body. When the outer (epidermis) layer of the skin separates from the fibre layer (dermis), a pool of lymph and other bodily fluids collect between these layers while the skin re-grows from underneath. If a blister is associated with sub-dermal bleeding it will partially fill with blood, forming a blood blister.
Blisters can be caused by chemical or physical injury. An example of chemical injury would be an allergic reaction. Physical injury can be caused by heat, frostbite, or friction.
Blisters typically develop when there is friction and irritation to the surface layer of the skin that cause it to separate from the second layer. Fluid fills in the space between these two layers. Blisters most often appear on the soles of the feet and palms of the hands. The hands and feet often rub against shoes, socks, or sports and music equipment and create friction under moist, warm conditions that are perfect for blisters.
Spyroflex Blister Dressings are specifically designed to absorb wound fluid and to cushion the blister from further painful contact and rubbing.
