After birth, newborns can see pinpoint-sized, dense yellow-white nodules on the tip of the nose and two nasal flanks, slightly above the skin surface, medically known as corn rash. About 40% of newborns will have it, and it usually subsides within 1 week after birth, which is a normal physiological phenomenon and does not require any treatment. This is a normal physiological phenomenon and does not require any treatment. The reason for this is that the sebaceous glands of infants are not fully developed and sebum accumulates, which disappears naturally after peeling. Corn rash most often appears on the upper cheeks, nose or chin of babies. Each baby behaves differently, some only have a little bit, some will have more. Note to parents: Do not squeeze the rash with your hands, as it can easily break and cause a local infection. 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 the nose, cheeks and other locations with rashes, using soft gauze dipped in warm water to wash, the water temperature should be appropriate, too cold or too hot will cause irritation to the baby’s skin. The action must be gentle, not to scrub hard in order to wash away the corn rash as soon as possible. Take care to protect these white dots and not to rub them, as long as the skin is not infected, the white dots will fade away without notice.
