Big milia under the eye: what to know

Milia are small cysts filled with keratin, a protein found in the outer skin. A bump that looks unusually large may instead be another type of cyst or skin growth, so appearance alone cannot confirm the diagnosis.

Typical milia feel firm and sit just beneath the skin rather than behaving like a pus-filled spot. They can occur around the eyelids and upper cheeks, where the skin is thin. Unlike acne whiteheads, they do not arise from an inflamed pore and may remain unchanged for some time.

Size, colour, surface texture and change over time help a clinician distinguish milia from blocked glands, other cysts and benign growths. Redness or tenderness suggests irritation or inflammation rather than uncomplicated milia.

Leave the bump intact and cleanse the area gently. Avoid needles, squeezing and harsh scrubs: pressure can injure delicate eyelid skin, introduce infection or leave a mark. Keep strong exfoliating products away from the eye unless a clinician has confirmed that both the product and placement are suitable.

A dermatologist can inspect the lesion closely. If removal is appropriate, the clinician may open and extract it with sterile instruments; treatment choice depends on its depth and exact position. Prescription topical retinoids sometimes help recurring milia elsewhere, but require special caution near the eyes.

Book an assessment if the bump is enlarging, changing colour, crusting, bleeding, painful or repeatedly inflamed. Seek prompt care for eyelid swelling, spreading redness, discharge, fever, eye pain or any change in vision. These features are not typical of a simple milium and need a direct examination.

Ask what features support the diagnosis, whether the bump can be observed, and which removal method protects the nearby eyelid. Mention previous attempts to treat it, products used around the eyes, recent injury or procedures, and whether similar bumps keep appearing.
