Don't wash that baby! study tests if keeping vernix on prevents eczema
NCT ID NCT07333378
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether leaving the white, creamy coating (vernix caseosa) on a newborn's skin for at least 24 hours after birth can prevent eczema (atopic dermatitis) during the first year of life. Over 1,300 mother-infant pairs in Chile will be randomly assigned to either keep the vernix on or have it washed off as usual. Researchers will track how many babies develop eczema and measure skin health and microbiome differences.

What this could lead to
If it works, this simple, no-cost change in newborn care could reduce eczema risk in infants worldwide.
What could go wrong
This is a single study in Chile; results may not apply everywhere. The intervention is subtle, so the effect may be small or hard to detect.
