1 Pemphigus vulgaris, a potentially fatal skin disease, causes blisters in the mouth or skin; these painful blisters become raw and crusted after bursting.  Bullous pemphigoid causes less severe blisters that heal faster and are not life-threatening; this condition is seen mostly in elderly people.
But there are also types of blisters that may have been caused by a medical condition, including fever and cluster blisters, impetigo blisters, atopic eczema blisters, or blisters from chickenpox, shingles and dermatitis herpetiformis.Here, we will focus on the most common types of skin blisters: burn blister occurs when the first two layers of skin are damaged by a second-degree burn. A burn blister is much like a water blister (except that it will be obvious it was caused by a burn as it is extremely painful). Like water blisters, burn blisters are also filled with an important watery fluid called serum.
