Definition

Noun: A milium is a small, white or whitish-yellow, raised bump on the skin. It is a type of tiny cyst that forms when keratin (a protein) becomes trapped beneath the surface of the skin, often due to a clogged sebaceous gland or hair follicle. Milia are common, harmless, and not contagious.

Usage

The word "milium" is a singular noun. Its plural form is "milia." It is a technical term used primarily in dermatology and skincare contexts to describe a specific, common skin condition.

Examples

• The dermatologist identified the tiny white bumps on the baby's nose as milia.
• A single milium can sometimes be mistaken for a whitehead, but it is not acne.
• Proper exfoliation can help prevent the formation of milia by clearing dead skin cells.

Advanced Usage

• Primary Milia: This term refers to milia that form directly from trapped keratin, commonly seen on the faces of newborns or adults.
• Secondary Milia: These develop in areas of skin that have been injured or damaged, such as after a burn, blistering, or excessive sun exposure.
