What is hypokeratosis?

Hypokeratosis refers to a condition characterized by a decrease in the thickness of the outermost layer of the skin, known as the stratum corneum. This layer is composed of dead skin cells that provide a barrier to protect underlying tissues and maintain hydration. When hypokeratosis occurs, it can lead to an impaired barrier function, making the skin more susceptible to irritation, infections, and moisture loss. This condition can be associated with various skin disorders and may present as dry, flaky, or sensitive skin.

The other options do not accurately describe hypokeratosis. Excessive skin shedding would indicate a different condition, often related to hyperkeratosis or other skin issues involving increased turnover of skin cells. A deficiency in the skin's barrier function can be a result of hypokeratosis but does not define it directly. An increase in oil production relates to conditions such as acne or seborrhea, which is unrelated to the concept of hypokeratosis. Understanding the specifics of how hypokeratosis impacts skin health is essential for proper skin assessment and treatment planning.
