Hyperkeratinization


Hyperkeratinization

Hyperkeratinization is a disorder of the cells lining the inside of a hair follicle. It is the normal function of these cells to detach or slough off () from the skin lining at normal intervals. The dead cells are then forced out of the follicle (primarily by the growing hair). However, in hyperkeratinization, this process is interrupted and a number of these dead skin cells do not leave the follicle because of an excess of keratin, a natural protein found in the skin. This excess of keratin, which is influenced by genetics, results in an increased adherence/bonding of dead skin cells together. This cohesion of cells will block or "cap" the hair follicle (leading to keratosis pilaris) or clog the sebaceous/oil duct (leading to acne).
