What is milia?

A condition characterized by excessive sweating
A hair follicle plugged with sebum and keratin
Benign, keratin-filled cysts that can appear just under the epidermis and have no visible opening
Thick scar resulting from excessive growth of fibrous tissue

The correct answer is: Benign, keratin-filled cysts that can appear just under the epidermis and have no visible opening

Milia is a common skin condition that is characterized by small, white or yellow bumps that typically appear on the cheeks, nose, and chin. These bumps are actually benign, keratin-filled cysts that form just under the surface of the skin and have no visible opening. While they may look similar to other types of skin conditions, such as acne or pustules, milia are not caused by excessive sweating (option A). They are also not hair follicles plugged with sebum and keratin (option B) or thick scars resulting from excessive growth of fibrous tissue (option D). Understanding the characteristics of milia can help distinguish it from other skin conditions and provide proper treatment.
