A blister is
a bubble of fluid under the skin. Blisters are the result of your body
detecting damage and building up fluids that help repair your body and fight
infection. Once the blister has done its job and rupture on its own, l know it's
hard not to do it yourself though!
Types of Blister:
Friction Blister: A blister occurs when the outer layer of the skin
separates from the fiber layer. The skin will re grow from underneath. The
loose skin is dead. Blisters can occur from heat, frostbite, chemical injury,
Blood Blister: A blood blister usually develops following a smashing or pinching injury.
There's a small skin injury that pumps blood between the skin layers, rising up
a blister of blood. Blood blisters can usually be treated at home.
