Vernix caseosa
Abbreviation: Vernix
Vernix caseosa is a white, waxy coating that forms on a baby's skin inside the womb, usually from around 20 weeks of pregnancy. It is made of shed skin cells, water, and oils, and acts as a natural moisturiser and protective barrier. At birth, some babies are covered in it, while others have very little, especially if they are born past their due date. Many hospitals now recommend leaving vernix on the skin for a short time after birth, as it helps retain moisture and may support the newborn's immune defences.
What This Means for You
Understanding Vernix caseosa is an important part of your birth/newborn journey. In your baby's first year, you will hear this term from your paediatrician and in parenting communities. Knowing what it means helps you respond quickly and confidently.

KKH and NUH both support delaying the first bath by at least 6 to 24 hours to allow the vernix to absorb naturally into the skin.
