You should also make sure your shoes fit properly. Wear the right clothing. During physical activity, wear moisture-wicking, loose-fitting clothes. Avoid clothes made of cotton, as cotton soaks up sweat and moisture, which can lead to friction and chafing. Consider soft bandages. For problem areas, such as the feet or thighs, consider using adhesive moleskin or other soft bandages.
Make sure the bandages are applied securely. Apply powder or petroleum jelly to problem areas. This helps reduce friction when your skin rubs together or rubs against clothing. Stop your activity immediately if you experience pain or discomfort, or if your skin turns red. Otherwise, you may get a blister. If you do get a blister, be patient and try to leave it alone. Most blisters heal on their own in one to two weeks. Cover the blister. Loosely cover the blister with a bandage.
Bring in the sides of the bandage so that the middle of the bandage is a little raised. If you buy through links on this page, we may earn a small commission. A blister is a pocket of fluid between the upper layers of skin.
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. Its purpose is to protect and cushion the layers below. Blisters can be filled with serum, plasma, blood or pus depending on how and where they are formed. In this article, we will discuss what blisters are, how they are caused and the best ways to prevent and treat them.
There are many activities and ailments that can induce blistering. Below are some of the more common ways that blisters can form. These blisters will usually appear on the hands or feet, as these are the areas that most often encounter repetitive abrasion, whether walking, running or playing the drums.
Areas of skin with a thick horny layer, attached tightly to underlying structures such as palms of hands and soles of feet are more likely to generate blisters. Blisters occur more readily if the conditions are warm, for example, inside a shoe. They also form more easily in damp conditions, compared with wet or dry environments. Blisters can lead to more serious medical issues such as ulceration and infection, although, under normal conditions, this is rare.
The timing of blister formation helps categorize burns. Second-degree burns will blister immediately, but first-degree burns blister a couple of days after the incident. At the opposite end of the spectrum, frostbite also produces blisters. In both cases, the blister is a defense mechanism deployed to protect lower levels of skin from temperature-related damage.
Skin can occasionally blister because of certain chemicals. This is known as contact dermatitis. If a small blood vessel near the surface of the skin is ruptured, blood can leak into the gap between the layers of skin causing a blood blister to form.
This is a blister filled with blood. Other types of blister are named after the condition they are linked to, such as chickenpox and shingles blisters and atopic eczema blisters. The most common type of blister for most individuals is the friction blister. In their most basic form, they occur due to increased shear stress between the surface of the skin and the rest of the body. The layer of the skin most susceptible to shear forces is the stratum spinosum.
As this layer tears away from the tissues below, a plasma-like fluid leaks from the cells and begins to fill the gap that is created.
This fluid encourages new growth and regeneration. Consult a doctor or other health care professional for diagnosis and treatment of medical conditions. For details see our conditions.
