Question: 1 / 400

Which skin condition is characterized by excessive oiliness?

Psoriasis

Dermatitis

Acne

Seborrhea

Seborrhea is a skin condition that is indeed characterized by excessive oiliness. It results from an overproduction of sebum, the oily substance that helps to keep the skin lubricated. This condition often leads to the appearance of greasy skin and can result in scaling or flaking, particularly on the scalp, face, and other areas where sebaceous glands are more concentrated.

In contrast, psoriasis is typically marked by dry, scaly patches due to rapid skin cell turnover, whereas dermatitis involves inflammation and may not necessarily present with excessive oiliness but could appear dry or irritated instead. Acne, while related to excess oil production, is primarily a result of clogged pores, inflammation, and the presence of bacteria. Seborrhea differentiates itself by focusing on the overall oiliness without the same inflammatory components associated with acne.
