Do You Know Blisters Can Be Caused By Eczema?

A blister, which is also called a vesicle by medical professionals, is a raised portion of skin that is filled with fluid. You’re probably familiar with blisters if you’ve ever worn ill-fitting shoes for too long.

Blisters can be caused by friction, infection, or, in rare cases, a skin condition. Here are 16 possible causes of blisters.


There are many temporary causes of blisters. Friction occurs when something rubs against your skin for a prolonged period of time. This happens most commonly on hands and feet.

 Contact dermatitis can also cause blisters. This is a skin reaction to allergens, like poison ivy, latex, adhesives, or irritants like chemicals or pesticides. It can cause red, inflamed skin and blistering.

 Burns, if severe enough, can produce blistering. This includes burns from heat, chemicals, and sunburns.

 Allergic eczema is a skin condition that is caused or worsened by allergens and can produce blisters.

Another type of eczema, dyshidrotic eczema, also results in blistering; but its cause is unknown, and it tends to come and go.

 Frostbite is less common, but it can cause blisters on skin that’s exposed to extreme cold for a prolonged period of time.

Blistering can also be a symptom of certain infections, including the following:

  • Impetigo, a bacterial infection of the skin that can occur in both children and adults, may cause blisters.
  • Chickenpox, an infection caused by a virus, produces itchy spots and often blisters on the skin.
  • The same virus that causes chickenpox also causes shingles, or herpes zoster. The virus reappears in some people later in life and produces a skin rash with fluid vesicles that can rupture.
  • Herpes and the resulting cold sores can lead to skin blistering.
  • Stomatitis is a sore inside the mouth that can be caused by herpes simplex 1.
  • Genital herpes can also result in blisters around the genital region.
  • Erysipelas is an infection caused by the Streptococcus group of bacteria, which produces skin blisters as a symptom.

More rarely, blisters are the result of a skin condition.
