A blister can develop if the skin is rubbed for a long period or if there's intense rubbing over shorter periods.

There are different types of burns that range from mild to severe and affect different layers of the skin. A first-degree burn affects the top layer of skin, or epidermis.

First-degree burns are minor and do not often cause burn blisters. First-degree burns may feel painful, look red, and may swell slightly. A sunburn is an example of a first-degree burn, or if skin touches something hot very briefly. People will usually be able to treat first-degree burns at home and find that the burn heals within a week.

Second-degree burns are slightly deeper, reaching the second layer of skin, which doctors call the dermis. Second-degree burns look red and often create burn blisters. Second-degree burns can range from mild to severe. People with mild second-degree burns will usually be able to treat their burn at home.

The burn or blister may need medical attention if it is large, causes severe pain, or becomes infected. Third-degree burns are severe, as they damage both the first and second layers of skin, and can damage the tissue, hair follicles, and sweat glands that lie under the skin. An example would be a mild sunburn that turns red and may peel. First-degree burns can generally be treated at home. Second-degree burns also called partial thickness burns go through the second layer of skin, called the dermis DUR-mis.

These burns cause pain, redness, and blisters and are often painful. The injury may ooze or bleed. They usually heal within 1 to 3 weeks. After healing, skin may be discolored. These burns generally do not leave raised scars. Treatment for second-degree burns varies. It may include ointments or special dressings. Surgery may be necessary for very deep second degree burns or those that are slow to heal.

Third-degree and more severe burns also called full thickness burns damage both layers of the skin and may also damage the underlying bones, muscles, and tendons. It may feel dry and leathery.

Sometimes there is no pain because the nerve endings under the skin are destroyed. Third-degree burns have a high risk of infection. They are usually treated with skin grafts. This surgery, done with general anesthesia, removes the injured skin and replaces it with healthy skin from an uninjured area of the body.

Full thickness burns that are not grafted may take months or even years to heal. Third-degree burns likely leave raised scars. Burn survivors may have a combination of first, second, and third degree burns.

Skin Grafts Larger areas of third degree full thickness burns are treated with skin grafts.

Sheet grafts are usually applied to the face or hands for better cosmetic effect. Sheet graft uses the whole piece of skin without the holes in it. It gives a better cosmetic appearance but requires much more skin to cover a specific area. Newly healed grafts are very fragile.

Special care should be taken to protect them. Be careful not to bump, rub, or scratch them. Do not wear rough clothing or anything that rubs; this can cause blistering. Meshed grafts are used for larger wounds. For permanent wound coverage, a piece of your own skin is taken from another part of the body donor skin to close the open area.

When the donor skin is taken off the body, it shrinks. To stretch the donor skin, it is put through a machine that makes small slits or holes in the skin. This stretched skin covers a larger area than an unmeshed sheet graft, but leaves a permanent mesh pattern similar to fish net stockings. The wound heals as the areas between the mesh and the holes fill in with new skin.

Once the mesh sheet sticks to the skin and the drainage stops, the wound is considered healed and can be left open to air.
