What causes herpes on the face? These three are the most common

Herpes is a common skin disease among people. Generally speaking, after people suffer from herpes, they are also very concerned about the causes of herpes on their faces. So, what causes herpes on the face?

1. Balloon degeneration and reticular degeneration

Due to intracellular edema, the volume of epidermal cells increases, forming a balloon shape. The cells swell and rupture, and the adjacent remaining cell membranes connect into multiple reticular septa, finally forming multilocular ulcers, which are more common in viral infectious skin diseases.

2. Spinolysis

Due to the degeneration of intercellular bridges (desmosomes and tension filaments, etc.) in the epidermis, the cells lose their tight connection and become loose, thus forming cracks, blisters or blisters in the epidermis. Acantholysis can be caused by autoimmune factors, such as pemphigus. Acantholysis caused by genetic factors is seen in chronic familial benign eczema and keratosis follicularis.

3. Spongioedema

Boils are formed due to the widening of the intercellular spaces caused by the increase of intercellular fluid. They are seen in eczema, contact dermatitis, and sweat herpes.
