What condition is characterized by dry, scaly skin due to decreased production of sebum?

  1. Asteatosis

  2. Impetigo

  3. Psoriasis

  4. Tinea

The correct answer is: Asteatosis

Asteatosis is the correct answer because it is a medical term that describes a medical condition in which the skin becomes dry, sometimes cracked and reddened. Asteatosis is caused by a decrease in the production of sebum, the natural oils produced by the skin. This condition can lead to dry, scaly skin. Impetigo, psoriasis, and tinea are incorrect options because they are not specifically related to a decrease in sebum production and do not directly cause dry, scaly skin. Impetigo is a highly contagious skin infection caused by bacteria, psoriasis is a chronic autoimmune disorder that affects the skin and joints, and tinea is a fungal infection of the skin. While these conditions can all cause skin abnormalities, they are not specifically linked to decreased sebum production like asteatosis.
