Warm environments aggravate the formation of blisters. Moist surrounding also contributes to a blistering skin surface. Even though it's rare, blisters may lead to infection of your neighboring healthy skin if you don't monitor it properly.
Blisters Due To Extreme Temperature
The timing of blister formation assists in categorizing burns. Second-degree burns will blister immediately, but first-degree burns blister some days after it happens. The other extreme end is formation of blisters due to frostbite. For both cases, blistering occurs to offer protection for soft underlying tissues against further damage from extreme temperature.
Does Chemical Exposure Result In Blisters?
Chemical agents may lead to your skin blistering, this type of blisters is known as contact dermatitis. It can affect some individuals in contact with the following:
- solvents
- detergents
- cosmetics
- Balsam of Peru, a flavoring

- Bullous impetigo: Mostly evident among infants under the age of two, blisters may develop on the arms, legs, or torso.
- Dermatitis herpetiformis is a chronic blistering skin complication similar to herpes in appearance even though they're unrelated.
- Cutaneous radiation syndrome which comes about due to side effects of radiation exposure.

A blister Forms When Stratum Spinosum Tears Due To Friction
Stratum spinosum is the skin layer that is most prone to the sheer pressure. The moment this layer rips off the tissues underneath, a fluid resembling plasma leaks and starts to fill the empty space. This fluid activates fresh growth and As this layer tears away from the tissues below, a plasma-like fluid leaks from the cells and begins to fill the gap that forms. This fluid encourages new cell growth and restoration.
Cells at the bottom of the blisters begin to utilize nucleosides and amino acid (protein blocks and DNA) on average 6 hours after the formation of the blister. Within a day, division of cells goes up greatly. Fresh layers of skin over the stratum spinosum develop constantly. A fresh skin layer will form after about 2 days, and following 3 days the top new layer of skin is eminent. The moment fresh cells form, fluid reabsorption occurs and the inflammation goes down.

Blister treatment
Most blisters heal without medical intervention. As the new skin forms beneath the blister, the fluid will slowly disappear, and the skin will naturally dry and peel off. If a blister is from a spider, chicken pox, cold sores, or persistent health conditions, you might require special treatment.
Treatment for a blister that has not popped
- Do not pop or drain it
- Do not cover it or cover it loosely with a bandage
- Do not pressure the blister. If the blister is a pressure region such as the bottom of the foot, put a mole skin on it.
Treatment for a blister that has popped
- Wash the area with warm water and gentle soap. Do not use alcohol, iodine, or hydrogen peroxide.
- Smooth down the skin flap that remains
- Apply antibiotic ointment to the area
- Cover the region loosely with a sterile bandage or gauze
Medical care
Management of friction blisters includes sterile drainage of the site while leaving the blister roof intact to serve as a dressing. This will help relieve some discomfort and protects the site from superinfection. You can also apply donut moleskin to reduce additional trauma to the blister and to relieve discomfort. In case the blister roof is already fully or partially removed, treat the site as an open wound with right antiseptic and surgical bandage application.
Hydrocolloid dressings have also been proven to reduce discomfort and promote healing. Some recommend debridement of the skin of the blister, the use of a topical containing nitrofurazone, and the application of a bandage.
Plastering a blister
Applying a blister plaster will assist in treating a blister without puncturing it. The plaster can:
- Help prevent additional pressure from shoes on to the blister
- Protect the sensitive protective layer of skin on top of the blister until the blister is ready to drain by itself
- Protect an open blister from being infected and external influences such as water, dirt, and bacteria getting in contact with the blister
Before using a plaster, always read the label. Use only as directed by a plaster. If symptoms persist, contact your healthcare practitioner.

Do not change the plaster wait until it comes off by itself. Give the blister time to heal.
You can use Elastoplast blister plaster with hydrocolloid technology to create an optimal moist wound healing environment that allows the wound to heal faster. So as not to inhibit the healing process, leave the plaster in place for several days and only change in case it starts to come off by itself.

However, if this does happen, you should disinfect the punctured blister (for example with an antiseptic spray) and cover it with a blister plaster. It will protect the affected area from further pressure, friction, and other harmful external influences.”
