The most common causes are friction, freezing, burning, infection, and chemical burns. Blisters are also a symptom of some diseases. The blister bubble is formed from the epidermis, the uppermost layer of skin.
Ideally, nothing. Blisters take roughly 7-10 days to heal and usually leave no scar. However, they can become infected if exposed to bacteria. If you don't pop a blister, it remains a sterile environment, virtually eliminating any risks of infection.
Plain petroleum jelly is a favorite among dermatologists for the treatment of wounds. Although the blister itself will act as a covering for the wound, if it happens to break, a person can cover the area with Vaseline and a bandage. This may promote healing of the area.
What causes blisters?

COVID-19 also has been reported to cause small, itchy blisters, more commonly appearing before other symptoms and lasting about 10 days. Others might develop hives or a rash with flat and raised lesions.
When should you be concerned about blisters? As discussed earlier, most blisters will begin to heal naturally on their own after a few days with proper care and hygiene. However, it is a concern if the blister is painful or becomes infected. Large painful blisters can be drained and treated by a trained professional.
Impetigo is a common skin infection, especially among children, that is usually caused by Staphylococcus bacteria. Symptoms include blisters and a rash. Impetigo is treated with antibiotics.
Bullous pemphigoid is an autoimmune disease that causes blistering of the skin.
The clear, watery liquid inside a blister is called serum. It leaks in from neighboring tissues as a reaction to injured skin. If the blister remains unopened, serum can provide natural protection for the skin beneath it. Small blisters are called vesicles.
2. For a Blister That Has Popped

A normal healthy blister contains thin watery blister fluid that is colourless or a very light yellow colour. Blister fluid will be pink or red in the case of a blood blister. However, pink/red doesn't mean your blister is infected.
A blood blister is essentially a common blister, but the blood vessels beneath the blister have been damaged. This causes blood to leak within, often turning the blister a dark red or purplish color.
Blisters are small pockets of clear fluid under a layer of skin. Blood blisters may look red or black and are filled with blood instead of clear fluid. An infected blister can be hot and filled with green or yellow pus. The surrounding skin may look red, but this can be hard to see on darker skin tones.
According to a 2018 article , a person should never attempt to pop a boil themselves. Popping or squeezing a boil can allow bacteria to infect deeper layers of the skin, as well as other tissues and organs. This can lead to serious, life-threatening complications. Boils can heal on their own without medical treatment.
Grab Yours! If you want to pop a blister without a needle, please just use something sterile – like a sterile scalpel blade, or a hypodermic needle. Use it just once, then discard safely into a sharps container.
Just keep in mind that blisters usually heal on their own within a few days. Popping a blister disrupts this natural process, and it could mean that your blister will take a little longer to completely disappear.
Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.
Most blisters heal naturally after three to seven days and don't require medical attention. It's important to avoid bursting the blister, because this could lead to an infection or slow down the healing process. If the blister does burst, don't peel off the dead skin.
If a blister bursts, bacteria can enter the wound and cause a skin infection. Certain types of blister develop when the skin rubs against other parts of the body or clothing. They look like a small pocket of raised skin containing a clear liquid.
It can quickly become a medical emergency if it spreads to your lymph nodes or bloodstream. Infected blisters can also lead to sepsis in severe cases. This happens when certain chemicals released by your immune system trigger a chain reaction in your body. Eventually, this can lead to septic shock.
