What should you know about white spots on a newborn forehead?

Milia are tiny, firm, pearly white cysts formed from trapped skin material. They commonly appear on a newborn’s face and are not the same as pus-filled pimples. Heat, saliva, friction from a hat, or a new product can add irritation around the area, while a red or crusted rash may have another cause.

Look at the baby rather than the spots alone: feeding, alertness, breathing, temperature, and hydration are useful context. Avoid trying to diagnose from colour alone, because several newborn rashes can look similar in a photograph.

Wash the forehead with lukewarm water and a mild, fragrance-free cleanser if needed, then pat dry. Keep hats loose and clean, avoid heavy oils and fragranced creams, and do not squeeze, pierce, scrub, or use adult acne products. Milia usually need observation rather than a procedure.

If the spots persist, spread, or the skin becomes inflamed, contact the baby’s clinician. Tell them when the spots began and whether they followed a product, heat, or rubbing.

Seek urgent medical advice if a newborn has a fever, seems unusually sleepy, feeds poorly, breathes differently, or has a widespread blistering or rapidly spreading rash. Contact a clinician promptly for pus, honey-coloured crusting, marked swelling, or redness near the eyes. A small, stable group of pearly spots on an otherwise well baby can usually be discussed at a routine visit.

Ask whether the appearance fits milia, whether any product should be stopped, and what changes should trigger a call. Mention the baby’s age, feeding and temperature, recent heat exposure, and whether the spots are itchy, red, or draining.
