Blisters: What Are They and How to Treat Them

Blisters are small, fluid-filled pockets that form on the top layer of the skin. Often painful and uncomfortable, they result from friction, burns, or other forms of skin irritation. Symptoms include a raised, bubble-like appearance, tenderness, and potential redness in the affected area. Treatment often involves protection, cleaning, and sometimes medication.

What Are Blisters?

Blisters are your body’s way of protecting deeper layers of the skin from further damage. They are typically filled with a clear liquid called serum, although they may also contain blood or pus if infected.

Types of Blisters

Common Causes of Blisters

Friction

When you wear shoes that don’t fit well or when you perform repetitive actions with your hands, friction blisters may form.

Burns

Exposure to extreme heat or cold can cause blisters. These can occur from cooking accidents, sunburn, or frostbite.

Medical Conditions

Certain illnesses, such as cold sores, chickenpox, herpes, impetigo, scabies, or eczema, can cause blisters to form on your skin.

Symptoms

When you have a blister, you may notice:

  • A raised area filled with fluid
  • Pain or discomfort
  • Redness around the blister

How Can You Treat Blisters?

When you have a blister, proper care is crucial. Here’s what you can do:

  • Don’t Pop It: As tempting as it may be, avoid popping the blister as it can cause infection.
  • Clean the Area: Use gentle soap and water to clean around the blister.
  • Protect It: Apply a bandage or other protective covering to keep it safe from further irritation.
  • Use Over-the-Counter Treatments if Needed: Special blister plasters or ointments may help.
