What are milia?

Milia are tiny, white, pearl-like cysts that form under the skin, typically as a result of trapped keratin and sebum. These small cysts can often be found around the eyes, cheeks, and forehead and are commonly seen in newborns but can occur in individuals of any age. They are not harmful and usually do not require treatment; however, their appearance can be cosmetic concerns for some individuals. The correct choice accurately describes milia as white pearly masses of sebum under the skin.

The other options describe different skin conditions: small, painful blisters represent conditions like herpes simplex or chickenpox, dark spots are indicative of hyperpigmentation due to UV exposure, and red patches are commonly associated with inflammatory skin conditions such as eczema or psoriasis. Each of these descriptions applies to distinct dermatological issues and does not accurately describe what milia are.
