What does hyperkeratosis mean?

Hyperkeratosis is a condition characterized by the thickening of the outer layer of the skin, known as the stratum corneum, due to an overproduction of keratin. This may occur in response to friction, irritation, or other stimuli and can manifest in various forms, such as calluses or warts. While often benign, it can sometimes indicate underlying skin disorders or health issues. Treatment typically focuses on addressing the underlying cause and may include topical treatments or lifestyle modifications.
