The Benefits of Vernix Caseosa

If you are like me, you saw the newest Johnson and Johnson commercial and cringed. The commercial sets the scene in a hospital room, a beautiful newborn baby is being bathed by a nurse. The narrator explains that this baby is just minutes old and that Johnson and Johnson is the brand most hospitals trust to wash newborns. But why do I, along with so many others find this cringe-worthy? It is because newborns are born with Vernix caseosa.

Vernix is a naturally occurring, cheesy like substance that coats the skin of newborns. This lipid-rich substance covers and protects the fetus from amniotic fluid during the third trimester but it also has a variety of benefits outside of the womb. Some of these awesome benefits are that it helps baby's skin surface adapt to it's new environment and keeps the skin moisturized. It has antioxidant properties due to the presence of vitamin E and melanin, and contains antimicrobial peptides(1). The best way to take advantage of these benefits is to rub the vernix into the baby's skin soon after birth, rather than wash it off.

In the womb, vernix works as a separation between the baby and the amniotic fluid. It is a lipid-rich substance that is unique to humans. Once baby is born it helps the skin defend itself from outside bacteria and fungal agents. More specifically it has been tested and shown beneficial to defend against E. coli, Group B Strep, Staph aureus, Pseudomonas aeruginosa, Candida albicans, Listeria monocytogenes, Serratia marcescens and Klebsiella pneumonia (2). All of which could be a potential risk for baby.

Skin is our biggest organ, and one that continues to develop after birth. A baby's skin is not fully mature until about twelve months of age, so it is important for parents to care properly for their baby's skin and to know about healthy bathing practices. It is advised to give baby a bath 2-3 times a week for the first six months while being aware of the soaps and detergents that could irritate or dry out baby's skin (3).

In conclusion, using a combination of healthy bathing practices as well as holding off your baby's first bath until the vernix is rubbed into their skin, has the potential to benefit your baby in the world outside of your womb. Although not every hospital follows this procedure, the benefits are becoming more well known. If you have any further questions or concerns, be sure to reach out to your health care provider.
