Blisters can have causes that aren't due to underlying disease. Examples include burns, friction injuries or trauma. A blister, which is also called a vesicle by medical professionals, is a raised portion of skin that is filled with fluid. You're probably familiar with blisters if you've ever worn ill-fitting shoes for too long. Blisters are most often caused by skin being damaged by friction or heat. Certain medical conditions also cause blisters to appear. The damaged upper layer of skin epidermis tears away from the layers beneath and fluid collects in the space to create a blister.

They're bubbles that pop up when fluid collects in pockets under the top layer of your skin. They can be filled with pus, blood, or the clear, watery part of your blood called serum. Most are shaped like circles. Depending on the cause, your blister could itch or hurt a lot or a little.

Dab on apple cider vinegar

Apple cider vinegar has antibacterial properties that will help prevent a popped blister from becoming infected. If it is too painful, try washing the area with hydrogen peroxide and covering with an antibacterial ointment.

Pop vitamin E

Vitamin E has excellent skin-repairing properties, as it helps skin cells heal quickly and prevents scarring. You can purchase vitamin E oil or creams, or pop open a vitamin E pill and apply the liquid directly to your blistered skin.

Apply castor oil

Castor oil is a popular home remedy for blister treatment. Apply before you go to bed, and let sit overnight to help your blister dry up and heal. You can mix the castor oil with apple cider vinegar to further aid healing.

Aloe vera gel

Aloe is an anti-inflammatory, so it will help reduce redness and swelling that cause pain. Studies have also proven that aloe is as effective as traditional medicines in healing second- and third-degree burns, making it an excellent home remedy for blisters.

They look like bubbles on the surface of the skin. Although they are often caused by irritation or friction (such as with a poorly fitting shoe), blisters can also represent disease processes. Blisters can accompany some types of skin rashes and inflammatory conditions, including certain autoimmune diseases. Depending upon the cause of the blisters, blisters may occur singly or in groups. In contrast to abscesses and boils, which are collections of inflammatory fluid found deep in the tissues, blisters are found in the most superficial layer of skin.
