Sebum is an oily substance produced by the sebaceous glands in the skin, and pus is a thick fluid that is produced in response to infection or inflammation. When sebum and pus combine, they can form a crust on the surface of the skin. This can occur in various skin conditions, such as acne or a skin infection. The crust serves as a protective barrier and helps to prevent further infection or irritation.Rate this question:

- A.
White heads
- B.
Nevus
- C.
Blackheads
- D.
Pimples
Correct Answer
A. White headsExplanation
Milia is a skin condition characterized by small, white bumps that typically appear on the face. These bumps are caused by trapped keratin, a protein found in the outer layer of the skin. Milia is often referred to as "white heads" because the bumps resemble small, white pimples or whiteheads. However, it is important to note that milia is different from traditional acne and blackheads. Nevus, on the other hand, refers to a birthmark or mole, and pimples are inflamed bumps on the skin caused by clogged pores. Therefore, the correct answer is white heads.Rate this question:
