Which classification of skin is more likely to develop a thicker stratum corneum?

Oily skin is characterized by an overproduction of sebum, which can lead to a range of conditions, including the tendency to develop a thicker stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells that act as a protective barrier. In response to excess oil and the need to protect against potential environmental irritants, the skin may produce more keratin, the primary protein in the stratum corneum, resulting in a thicker layer.

Additionally, thicker stratum corneum in oily skin can be a compensatory mechanism, helping to maintain hydration and protect the skin from dehydration. This thickening may also contribute to issues like clogged pores if not properly managed, leading to acne and other related skin conditions.

Other skin types, such as dry, combination, or sensitive skin, do not typically exhibit a thicker stratum corneum. Dry skin often has a thinner layer due to a lack of moisture and lipids, while combination skin presents a mix of characteristics that do not favor a significant thickness in any one area of the skin. Sensitive skin can show irritation and can respond with a thinner protective layer rather than a thicker one. Thus, oily skin stands out as
