Managing Minor Burns: What to Do After a Small Blister Forms - Dermatology

Share to:

Hello, Dr. Wu. Recently, during the Mid-Autumn Festival barbecue, I got splattered with oil?


It's not a very large wound, located on the back of my hand, approximately 0.3 to 0.5 mm in size.
At the time, I was sprayed and rinsed it with cold water for about 10 minutes.
Shortly after, a small blister of about 0.3 to 0.5 mm formed.
This occurred just yesterday, and today I noticed a slight stinging sensation on the back of my hand.
Upon inspection, I found that the blister had burst halfway, leaving only a portion of the skin attached.
The contents of the blister had turned into a dry, soft substance, somewhat resembling the white, pasty material that comes out of a popped pimple.
I'm unsure if this is dried tissue fluid.
After the blister burst, I gently removed the skin that was still attached to my hand.
The wound appears clean and is the same color as my skin, but it has a slight sheen, resembling a minor abrasion with a small area of missing outer skin.

I'm uncertain whether I should apply medication or just leave it alone, as the wound now looks like a clean, minor abrasion.
I only rinsed it with unopened saline solution from a previous car accident, which expires in 2025, but I couldn't find the antibiotic ointment from the accident, so I didn't apply any medication.
According to information online, blisters typically indicate a superficial second-degree burn, and based on the size of my blister, I feel it falls between first and superficial second-degree burns.
However, the internet also states that blisters usually take about 3 to 7 days to heal, yet mine fell off after just one day.
I'm not sure if it came off on its own or if I inadvertently rubbed it against something.

I cannot determine whether you need to see a doctor or apply medication, as I have not seen the condition of the wound.
If you are concerned, it is advisable to seek medical attention promptly to avoid any delay in treatment.

Managing minor burns, especially those that result in blisters, requires careful attention to ensure proper healing and to minimize the risk of infection. Based on your description, it sounds like you've experienced a minor burn that has resulted in a small blister on your hand. Here’s a detailed guide on how to manage this type of injury.


Immediate Care
1. Cool the Burn: It seems you have already done this by running cool water over the burn for about 10 minutes. This is the first and most crucial step in managing a burn, as it helps to reduce the temperature of the skin and minimize tissue damage.

2. Do Not Pop the Blister: If the blister is intact, it is best to leave it alone. The blister acts as a protective barrier, helping to prevent infection. If the blister has partially broken, as you described, it’s important to keep the area clean.

3. Clean the Area: You mentioned using saline solution to rinse the area, which is a good practice. Ensure that the area is gently cleaned with mild soap and water, followed by rinsing with saline or clean water. Pat the area dry with a clean towel.


Aftercare
1. Moisturize and Protect: If the blister has broken, apply a thin layer of an antibiotic ointment (like Neosporin) if you have it available. This can help prevent infection. If you don’t have an antibiotic ointment, you can use a sterile, non-stick bandage to cover the area. This will protect it from further irritation and keep it moist, which is beneficial for healing.

2. Monitor for Infection: Keep an eye on the burn for signs of infection, which include increased redness, swelling, warmth, or pus. If you notice any of these symptoms, it’s important to seek medical attention.

3. Avoid Irritation: Try to avoid any activities that might cause friction or irritation to the burn area. This includes avoiding tight clothing or any repetitive motions that might rub against the blister.

4. Pain Management: If you experience pain, over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage discomfort.


Healing Process
- Healing Time: Minor burns, especially those classified as first-degree or superficial second-degree burns, typically heal within 3 to 7 days. The blister may take a few days to fully resolve, and the skin underneath will gradually heal.

- Scarring: In most cases, minor burns heal without significant scarring, especially if they are cared for properly. However, the area may appear slightly different in color as it heals, which is normal.


When to Seek Medical Attention
- If the burn covers a large area, is on the face, hands, feet, or over a major joint, or if you have any concerns about the severity of the burn, it’s advisable to consult a healthcare professional.

- If you notice signs of infection or if the pain worsens, seek medical advice promptly.


Conclusion
In summary, for your minor burn with a blister, continue to keep the area clean, protect it with a bandage, and monitor for any signs of infection. If you have access to antibiotic ointment, use it to help prevent infection. Most importantly, avoid popping the blister, as this can lead to complications. If you have any concerns or if the condition worsens, don’t hesitate to seek medical advice. Proper care will help ensure a smooth recovery and minimize any potential scarring.
