Skin Blisters Diagnosis
Blisters are small pockets of fluid between the upper layers of the skin. They typically occur on the hands and feet but can form anywhere on the skin. The fluid may appear clear -- serum also called water blisters, plasma -- blood or blood blisters, or pus -- infection.

Burns
-
Causes of blisters include burns from either hot water or oil, and severe sunburns.
Friction
-
Friction blisters commonly result from a tear between the layers of the epidermis and the lower layers of the skin. A blister forms when the surface of the skin is not torn and serum collects and pushes outward in the space created between the layers of skin.

Reaction
-
Blisters can also result from a reaction to detergents, solvents, cosmetics or other chemicals. Allergic reactions to insect's bites and stings can also cause blisters to form.
Medical Conditions
-
Some medical conditions also cause blisters including herpes, chicken pox, impetigo, and eczema, along with other, rarer, conditions such as bullous pemphigoid, pemphigus and herpetiformis.
Care
-
Leave blisters alone and allow them to heal on their own. If you pop a blister you increase your chance of infection. Cover the blister with gauze and a bandage to protect it so that fluids can re-absorb into the skin over time.
