What is hyperkeratosis?

Hyperkeratosis refers to a condition characterized by the accumulation of excessive amounts of dead skin cells in the outer layer of the skin, known as the stratum corneum. This buildup results from an increase in keratin production, which occurs as a response to various factors such as friction, irritation, or certain skin conditions. The process of cell turnover, which involves the shedding of old skin cells and the generation of new ones, may become disrupted, leading to the persistence of these dead cells on the skin's surface.

In essence, hyperkeratosis can manifest as thickened areas of skin, sometimes appearing dry or scaly. Conditions that lead to hyperkeratosis include calluses, psoriasis, and certain types of dermatitis. Understanding hyperkeratosis is vital for skincare professionals, as it influences treatment approaches for clients suffering from this condition. The other options describe different skin conditions that are not directly related to the process of keratin accumulation and cell turnover.
