How long does it take for a blister to heal?

Blister healing time depends on many factors. In most cases, they will disappear on their own, but it may take longer than expected.

Time for healing a blister is variable. The smaller the blister, the quicker it will heal. If your blister is large, it will take more time to heal. 

How fast and how well a blister heals also depends on the type of blisters:

Blisters can also be caused by contact dermatitis, dyshidrotic eczemashingles, frostbite or some autoimmune blistering diseases.

What’s the average healing time for a friction blister?
Friction blisters usually heal up quickly within a week without scarring. But if there is continued pressure or friction on your blister, it may take more than two weeks for the blister to heal.

Fever blisters (also called cold sores) usually crust within 4 days. It usually takes between 8 to 10 days for a fever blister to heal.

Do sunburn blisters heal faster?
Blisters from a sunburn should only take a few days to heal, but it depends on the severity of your sunburn. The blisters don’t always show up right away. They may take a few days or longer to develop. Don’t forget to protect your skin from sun while it’s healing from the burn. Here you’ll find tips for sunburned lips.

What about autoimmune blistering diseases?
Autoimmune blistering diseases are a group of disorders in which the body mistakenly attacks healthy tissue, causing blistering lesions. These types of blisters obviously take longer to heal.

Factors that can slow down the healing process

Healing can be delayed for several reasons:


If the blister breaks open, the risk of infection increases and you may develop a deeper wound. 

In most cases a blister heals faster if you don’t pop it. Blisters protect the skin underneath as it heals. If they get peeled off, the skin can get infected more easily.

If a blister needs to be popped for whatever reason, then the fluid should be drained using a sterilized needle to lower the risk of infection.

Read this article that explains why blisters are not supposed to be popped

The location of the blister

Areas that move or are more sensitive require more time to heal.


Studies show that bad nutrition can slow down healing. Check this post to learn about foods and supplements that promote healing.

Diabetes and impaired immunity diseases

People with diabetes often have nerve or circulation problems that cause wounds to heal more slowly. 

Infection is also more common in diabetics and immune impaired individuals. If your immune system is weak, the risk of infection increases.


Here are the drugs that can slow wound healing:

  • corticosteroids
  • cytotoxic antineoplastic and immunosuppressive agents,
  • nonsteroidal anti-inflammatory drugs (NSAIDs)
  • anticoagulants

Smoking and alcohol

Studies show there’s a delay in wound healing in smokers. Drinking alcohol can also impair wound healing and increase the risk of infection.

If your blister pops, protect your blister with a bandage to prevent infection. Studies show that a covered wound heals faster than an uncovered wound.

Which remedies help Decrease blister heal time?

There are some natural ways to help heal blisters faster. Here are a few ideas to speed up healing:

Aloe Vera

Aloe Vera is a natural anti-inflammatory. It helps to relieve swelling and redness and keeps the skin hydrated and moist. It helps in faster healing especially when the blister pops and shrivels up. (source)


  • Simply take an aloe Vera spine and cut it open.
  • Apply the clear gel directly to the blister.
  • Leave the blister uncovered for 15-30 minutes until the gel is completely absorbed and then rinse with warm water.
  • Apply 2-3 times a day for 3-4 days

Another way to use aloe vera is by mixing natural aloe vera gel and vitamin E oil in equal amounts. 

Apple cider vinegar

Apple cider vinegar (ACV) has antibacterial properties and inflammatory properties as well. It can be used to prevent infection when the blister pops. (source)

How to use apple cider vinegar for a blister?

  • Use a cotton wool and dip it in the vinegar.
  • Apply it close to the affected area three to four times in a day for about three days.
  • For best results, apply it as soon as the blister appears. Note that it is likely to sting, especially of the blister has popped. This can be prevented by diluting with water. 

You can also mix a teaspoon of apple and cider vinegar with the same amount of onion paste.

  • Apply the solution on the blister and then leave it to dry. Rinse off the area using warm water. 
  • Apply two times a day for a few days. 

Choose a high quality and organic ACV brand. Here’s my favorite brand of Apple Cider Vinegar.

Green tea

Green tea is useful due to its anti-inflammatory compounds which work well in reducing pain and swelling that comes with blisters. It also has a couple of vitamins and antioxidants that act as catalysts to heal the blister. 

  • Place 1 green tea bag in hot water for 5 minutes.
  • Remove the teabag and leave it to cool for some seconds then place the moist teabag on the affected area some few minutes.
  • Do this for 4 to 5 times every day for a few days. 
  • You can also take a cup of green tea 2 to 3 times in a day to quicken the healing process. 

Epsom salt

This one of the safest ways to heal blisters. It works by helping to dry out a blister that is not popped and encourages it to drain. The salt has high content of magnesium, which helps to reduce swelling and pain as well as infection. 

  • Use 1 to 2 tablespoons of Epsom salt.
  • Put it in some small amount of warm water and stir well. 
  • Soak the affected area in the water for 15 minutes.
  • Remove the affected area from the solution and dry it gently.
  • Apply vitamin E. 
  • Do this once a day every day. 

Note: when the blister pops, the Epsom salt can sting, and it is therefore advisable to stop using it. 

Tea tree oil

Tea tree oil has astringent properties and also antibacterial properties. It treats and reduces the infection of blisters.

  • Dilute one part of tea tree oil using either three parts of plain water or any vegetable oil. Take a cotton ball and dip it into the mixture and then apply it to the affected area. 
  • Allow it to settle for 10 minutes and then rinse using cold water. 
  • Use the remedy for 2 to 3 days for some few days. 

White toothpaste for friction blisters

This can be used to dry out a blister quickly. It is useful as it contains hydrogen peroxide, menthol, baking soda, and alcohol. It also gives quick relief from itchiness. (source)

  • Put a small amount of toothpaste on a clean finger. Do not use colored toothpaste or whitening gel.
  • Smear it on the area with the blister and leave it to rest for about 2 hours. 
  • Do this 1 to 2 times daily until the blister is gone. 

Eating the right diet for faster healing

Your body is built to heal from the inside out. So eating nutritious foods are important in the healing process. 

Follow a diet rich in Vitamin C, A and bioflavonoids to promote healing and fight infection. This means that you should eat fresh, raw vegetables and fruits. They provide enzymes to boost your immune system. Dark green and orange vegetables contain beta-carotenes, which are important to speed up healing.

Protein is one of the most important nutrient factors affecting wound healing. Opt for fish, eggs, seeds, nuts, legumes, and grains rich in proteins, such as quinoa.

Now, which foods should you avoid? Limit sugar and processed foods, since they slow down tissue regeneration.

Also follow these nutrition guidelines to promote healing.
