What skin condition is indicated by an increase in the accumulation of dead skin cells?

The condition associated with an increase in the accumulation of dead skin cells is hyperkeratosis. Hyperkeratosis occurs when there is an excessive buildup of keratin, which is the protein that makes up the outer layer of skin. This buildup can result from various factors, such as chronic friction, pressure, or certain skin conditions.

In hyperkeratosis, the skin appears thickened and can lead to rough, scaly patches. This thickening serves as a protective response but can also inhibit the normal shedding process of dead skin cells. In contrast, conditions like psoriasis involve not just the accumulation of dead skin cells but also accelerated skin cell turnover, leading to scaling and inflammation. Acne primarily involves clogged pores and inflammation, while eczema is characterized by inflammation and itching rather than an accumulation of dead skin cells. Thus, hyperkeratosis is the best answer as it specifically highlights the increased accumulation of dead cells on the skin.
