Which skin condition is characterized by high oil content and dead skin cells?

The correct answer is characterized by high oil content and dead skin cells is acne. Acne is a common skin condition that occurs when hair follicles become clogged with oil (sebum) and dead skin cells. This blockage can lead to the development of various types of lesions such as blackheads, whiteheads, and pimples.

The condition typically arises due to factors like hormonal changes, bacteria, and increased production of oil. The presence of excess oil combined with the buildup of dead skin cells creates an environment conducive to the growth of bacteria, resulting in inflammation and sometimes leading to more severe forms of acne.

While conditions like eczema and psoriasis also involve skin irregularities, they do not primarily focus on the combination of high oil content and dead skin cells as acne does. Milia, on the other hand, are small cysts that occur when keratin becomes trapped beneath the surface of the skin, which is not related to oil production or the buildup of dead skin cells in the same manner as acne. Thus, acne distinctly fits the criteria set forth in the question regarding high oil content and dead skin cells.
