What Exactly Is Blisterata?


Ever get those annoying little bumps that pop up out of nowhere? You know, the clear ones filled with fluid that hurt when you walk or put on shoes. Chances are you’ve experienced blisterata at some point. Blisterata refers to a common skin condition where fluid-filled blisters form, typically on your feet, hands, or other areas that experience friction or pressure.

While blisterata sounds like some rare tropical disease, it’s really just the medical term for blisters. Blisterata forms as a result of excess friction or other minor skin damage that separates the outer layer of skin from the lower layers. Fluid fills the space between, creating the familiar bump you know and loathe.

The good news is blisterata is usually not serious and will clear up on its own in a few days as new skin forms underneath. However, blisterata can be painful, and in some cases, may require treatment to avoid infection or promote healing.

What Is Blisterata? Defining This Mysterious Skin Condition

So what exactly is blisterata? This mysterious skin condition causes fluid-filled blisters to form, usually on the hands and feet. ###

Blisterata, also known as dyshidrotic eczema, typically causes itchy blisters on the palms of your hands and sides of your fingers and toes. The blisters start as small red bumps, then fill with clear fluid before crusting over and peeling. An flare-up can last for weeks and the blisters may come and go.

The underlying cause of blisterata is unknown, though it’s believed to be an allergic reaction to something you’ve touched. Common triggers include:

  1. Nickel or cobalt – Found in jewelry, coins, tools, etc.
  2. Chromates – Used in cement, leather, and carpentry.
  3. Plants such as primrose or tulips.
  4. Stress and sweating – Can irritate the skin and trigger a flare-up.

To ease symptoms, avoid potential triggers, keep your hands and feet well moisturized, use cold compresses, and take an oral antihistamine. Corticosteroid creams may help reduce inflammation and itching. In severe cases, light therapy or oral medications are options to discuss with your dermatologist.

The good news is blisterata is not contagious and typically clears up once you eliminate the underlying cause. By learning to recognize your triggers and following preventive measures, you can keep flare-ups under control and your hands and feet as blister-free as possible.

Common Causes and Triggers of Blisterata

So, your skin is suddenly erupting in little blisters and you have no idea why. Don’t panic – blisterata, while annoying, is rarely serious and often caused by common triggers.

Exposure to heat or sunlight

Extended sun exposure can cause blisterata, especially at the beginning of summer when your skin isn’t used to the intense UV radiation yet. Wear sunscreen with an SPF of at least 30, limit time in the sun during the peak hours of 10 AM to 4 PM, and wear sunglasses and a hat.

An allergic reaction

Have you started using any new skin care products, makeup, laundry detergent, or medications recently? An allergic reaction could be to blame. Stop using anything new and see if your symptoms clear up. If they persist for more than a week, consult your doctor. They may prescribe oral antihistamines or hydrocortisone cream to reduce inflammation.


In some cases, a bacterial infection like impetigo or a viral infection such as herpes or chickenpox may cause blisterata. You’ll need oral or topical antibiotics to treat infection. See your doctor if blisters are severe, painful, or accompanied by other symptoms like fever or chills.

Irritant contact dermatitis

Exposure to harsh chemicals, fragrances, metals like nickel, or other irritating substances may irritate your skin and cause blisterata. Avoid the irritating substance and apply a cortisone cream to help with inflammation and itching. The blisters should clear up within a week.

With care and by avoiding triggers, most cases of blisterata will disappear on their own. But see a dermatologist if symptoms worsen or last more than two weeks.

Treating Blisterata: Relief Options and When to See a Doctor

Treating blisterata typically involves relieving symptoms and allowing the infection to clear. Here are some options for finding relief:

  • Apply a warm compress. Place a warm, wet washcloth over the blisters for 10-15 minutes, a few times per day. The heat will help reduce pain and may speed up draining and healing.
  • Take an over-the-counter pain reliever. Use acetaminophen, ibuprofen, naproxen or aspirin to reduce pain from blisters. Follow the dosage instructions on the packaging.
  • Use an antibiotic ointment. Apply an ointment like bacitracin, neomycin, or polymyxin B 4 times a day to help prevent infection while the blisters heal. Make sure to wash hands first and dry blister area thoroughly.
  • Allow blisters to drain on their own. Do not pop blisters unless they are very large, as this can lead to infection. If a blister pops on its own, wash the area thoroughly with soap and water and apply an antibiotic ointment. Cover it with a sterile bandage or gauze.
  • See a doctor if:

• Blisters are severe or widespread, especially if they involve the eyes or genitals

• You have signs of infection like swelling, redness, increased pain, or pus

• New blisters continue to appear after a week of home treatment

• Blisters are accompanied by a high fever or body aches

• You have a condition like diabetes or a weakened immune system

A doctor may need to drain, culture and test the fluid. Oral antibiotics or steroid creams may also be required in some cases to help clear the infection and reduce inflammation. Be sure to get medical help right away if blisterata is severe or does not start to improve within 7-10 days using home treatments.
