Which of the following is a benign, keratin-filled cyst that appears around the eyes, cheeks, and forehead?

A benign, keratin-filled cyst that appears around the eyes, cheeks, and forehead is known as a milia. Milia often form as small, white, raised bumps on the skin, particularly in areas such as the face, and they are caused by the buildup of keratin beneath the epidermis. These cysts are generally harmless and do not require treatment unless desired for cosmetic reasons.

Understanding the characteristics of milia is important for cosmetologists, as they might encounter clients with these cysts and need to differentiate them from other skin conditions. Unlike warts, which are caused by a virus, or acne cysts, which are an inflammatory response related to acne, milia are distinct in their formation and appearance. Similarly, fibromas are benign tumors of connective tissue and do not have the same keratin-filled nature as milia.
