Milia
Pronunciation: MIL-ee-ah (singular: MIL-ee-um)
Small, superficial epidermal inclusion cysts containing keratin, appearing as white or yellowish papules, which may arise spontaneously or as a complication of cosmetic procedures.
Full Definition
Milia (singular: milium) are benign keratin-filled cysts located just below the skin surface, commonly found on the face, particularly around the eyes. In cosmetic dermatology, they are relevant both as a pre-existing condition and as a documented complication of ablative procedures, heavy occlusive topicals, or injectable filler. Editors should note that 'milia' is already plural—'milias' is incorrect. The singular 'milium' is rarely needed in editorial contexts but should be used correctly when referencing a single lesion. A common confusion is with syringoma (a benign sweat duct tumour), which requires a different editorial framing.
Usage
Usage note: 'Milia' is plural; never write 'milias'. Use 'milium' for a single lesion in clinical text.
