What is the main characteristic of milia?

• A. It is a form of acne
• B. It is a skin condition resulting in fluid-filled cysts
• C. It appears as white tiny cysts on the skin
• D. It is a type of dermatitis

Answer: (C)

Milia are small, white cysts that typically appear on the skin, particularly around the eyes and cheeks. They are composed of keratin, which is a protein that makes up the outer layer of the skin. The tiny cysts form when keratin becomes trapped beneath the surface of the skin, resulting in the characteristic white appearance. These cysts are harmless and often do not require treatment, although they can be removed by a dermatologist if desired.

While some options describe skin conditions, milia specifically stand out due to their unique presentation as white cysts, which helps to distinguish them from other skin issues, such as acne or dermatitis. Understanding the defining features of milia is important for proper identification and treatment in a clinical setting.
