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.
Blisters are generally caused by friction against the skin, allowing a fluid build-up under the section of skin being rubbed. Many doctors and dermatologists wanting to prevent scarring and infection will recommend that you do not pop your blister, but if you really want to pop it, follow these steps to do it safely.
