Beyond the First Bath: The Gentle Science of Vernix Caseosa
A touching image of a newborn baby is going viral online. In the photo, a healthcare professional is gently wiping a thick, creamy white layer from the baby’s back just moments after birth.
Many viewers were surprised and asked:
“What is that white substance?”
The answer is something completely natural — and incredibly important.
🤍 What Is That White Layer?
The white, creamy coating seen on newborn babies is called vernix caseosa.
It is a natural, protective substance that forms on a baby’s skin during pregnancy.
This layer develops in the womb during the third trimester and plays a very important role before birth.
