What is hyperkeratosis characterized by?

Hyperkeratosis is characterized by an increased thickness of the epidermal layer of the skin. This condition occurs when there is an overproduction of keratin, a protein that helps form the outer layer of skin, leading to the thickening of the skin. This response can be due to various factors such as friction, pressure, or irritation, and is commonly seen in areas of the skin that experience repeated trauma or stress.

Increased thickness can result in rough patches, warts, or calluses, which are often a protective response of the skin to prevent further injury. Understanding hyperkeratosis is essential in athletic training as it can impact an athlete's performance and comfort level, particularly in sports involving repetitive motions or areas prone to friction.
