After birth, newborns can see small, pinpoint-sized, dense, yellowish-white nodules on the tip of the nose and both nasal flanks, slightly above the skin surface, medically known as corn rash. It most often appears on the baby’s upper cheeks, nose, or chin. Occasionally, the milia may appear on the baby’s gums or palate. About 40% of all newborns will have a corn rash, which usually subsides within 1 week after birth and is a normal physiological phenomenon that does not require any treatment. The reason for this is that the sebaceous glands are not fully developed and the skin secretions cannot be discharged from the surface of the skin and accumulate inside, forming a white corn-like rash. Note to parents: Do not use your hands to squeeze the corn rash, it is easy to squeeze and then cause local infection. Do not scrub the affected area as it may irritate the sensitive skin of the newborn. Do not apply topical medications or ointments to the rash area, as ointments generally contain hormones, which can affect the baby’s endocrine system after absorption through the skin. The correct response: bathe your baby every day, especially on the nose, cheeks and other locations with rashes, and wash with soft gauze dipped in warm water, the water temperature should be appropriate, too cold or too hot will cause irritation to the baby’s skin.
