What Is the white substance that is produced by the sebaceous glands and protects the baby's skin?

The white substance produced by the sebaceous glands and found on a baby's skin is called vernix caseosa. This creamy, protective coating serves to shield the baby's skin from amniotic fluid during pregnancy and helps to moisturize and prevent irritation after birth. It is typically present at birth and gradually disappears in the first few weeks of life. Vernix also has antimicrobial properties that can protect against infections.
