In<unk> , the autoimmune reaction occurs in the skin, specifically at the level of the basement<unk> , which connects the lower skin layer (dermis) to the upper skin layer (epidermis) and keeps it attached to the body. When the condition is active, the basement<unk>  is dissolved by the antibodies produced, and areas of skin lift away at the base, causing hard blisters which scar if they burst. In other words, this is a desquamating/blistering disease in which the epithelium "unzips" from the underlying connective tissue, allowing fluid to gather that subsequently manifest as bullae, or blisters.
