Vernix caseosa is the white, waxy coating that protects a baby's skin in the womb. Babies born early often have more of it; any that remains at birth can be left to absorb into the skin naturally.

Key takeaways

  • Vernix acts as a natural moisturiser and barrier.
  • Babies born after their due date may have little vernix and peeling skin.

Frequently asked questions

No. It does not need to be scrubbed away and is absorbed naturally.
