Blisters

A blister is a soft area of skin filled with a clear fluid. Blisters resulting from injury or friction typically manifest as localized bubbles filled with either clear or bloody fluid. These blisters are often specific to the affected area and are characterized by their response to physical stress or irritation. On the other hand, blisters associated with underlying conditions may appear in isolated regions or affect the entire body.

Dermatology Affiliates' dermatologists approach blister treatment based on the underlying cause and severity of the blisters. Explore more details on blisters below. If you’re suffering from painful skin irritants, schedule a skin consultation. Our skin experts can advise on proper care and monitoring to ensure your blisters heal effectively without complications.
 

What are the Symptoms of Blisters?

  • Blisters appear as a fluid-filled sac or bubble on the skin.
  • Pain or tenderness at the blister site.
  • Redness or inflammation around the blister
  • Possible swelling or warmth around the blister.
  • Sensitive or tingling sensation before the blister appears.
     

Causes of Blisters

  • Blisters often result from friction, especially when fabric repeatedly rubs against the skin.
  • They can form in response to a chemical or allergic irritant, a condition known as contact dermatitis.

How to Prevent Blisters

Preventing blisters is achievable by eliminating the irritant and adopting simple preventive measures. Ensure comfort and minimize the risk of blisters by following these practical tips:

  • Avoid Tight Clothing: Opt for well-fitting clothing to prevent unnecessary friction. Choose breathable fabrics that reduce moisture and heat, decreasing the likelihood of blister formation.
  • Properly Fitting Footwear: Wear shoes that fit correctly, providing ample space for your toes. Opt for moisture-wicking socks to keep your feet dry during physical activities.
  • Use Work Gloves: When engaging in heavy manual work, wear appropriate work gloves. Gloves protect your hands from friction, pressure, and irritants, reducing the risk of blisters
  • Identifying & Avoiding Irritants: This is crucial in preventing the occurrence of contact dermatitis-induced blisters.

By incorporating these practices into your daily routine, you can minimize the potential for blisters and enhance overall comfort.

FAQs for Blisters

It’s advised not to pop a blister because it acts as a natural protective barrier against infection. If you pop a blister, you can expose the skin underneath to bacteria, raising the risk of infection. If a blister is causing significant pain or discomfort, or if there are signs of infection, it's advisable to consult a dermatologist for proper evaluation and care.

You should schedule an appointment with your dermatologist if your blister:


  • Is sizable or affects a large area of the body.
  • Shows signs of infection, such as heat, redness, increased pain, or filled with puss
  • Occurs alongside a severe burn, allergic reaction, or an underlying medical condition.
  • Reoccur or do not heal.

If you're worried about the blister’s appearance, symptoms, or potential complications, it's advisable to consult your dermatologist or healthcare provider for a thorough evaluation and appropriate care.





Caring for a blister properly can help it heal faster and prevent infection. Here are some common tips:

  • Do not pop the blister.
  • Softly wash the blister gently with mild soap and water.
  • Use antibiotic ointment.
  • Keep blister clean and covered. 

If the blister is large, painful, or shows signs of infection, see your dermatologist.

Blisters commonly form from friction or burns. They can be managed at home by cleaning the area, protecting it with a sterile bandage, and avoiding popping it. If you commonly get blisters, have large, painful, or infected ones, or if a blister appears without a known cause or in sensitive areas, schedule an appointment with your dermatologist. They can evaluate the blister, offer specialized treatment, and identify any underlying skin conditions that may be causing the problem.

Blister Treatments

Dermatologists employ effective treatments for blisters, addressing the cause and promoting rapid healing. From specialized topicals to expert drainage techniques, they ensure personalized care.

Although medical intervention is not always needed to treat blisters, we recommend you do not pop your blisters at home as that can cause infection. If a blister does open on its own, be sure to leave the covering in place to support further healing. Simply wash the area gently with mild soap and water, pat it dry and apply an antibacterial ointment. Cover the blister with bandage to keep it clean. Replace the dressing at least once a day.


If your blisters are recurring, don't endure discomfort—schedule a dermatology appointment promptly for relief and optimal recovery.
