Is this trial a fit for you?

Likely a good fit

Pregnant women aged 18 or older delivering a healthy singleton baby at one of the study sites and able to consent, with follow-up willingness.

Probably not a fit

Premature or low birthweight babies, multiple gestations, or cases with maternal infections or neonatal illnesses may not benefit and are excluded.

What this trial studies

This interventional study explores a primary prevention approach for atopic dermatitis by modifying newborn skin care at birth. Two strategies are compared: retaining vernix caseosa on the skin versus removing it after birth. The trial enrolls healthy, singleton newborns delivered at participating Chilean hospitals and follows standard postoperative and neonatal care schedules to monitor skin barrier function and early signs of eczema. The rationale is that vernix contains protective lipids and antimicrobial components that might support skin barrier integrity during a critical window of immune development. Results will inform whether vernix retention could be a feasible, low-cost strategy to reduce the burden of atopic dermatitis in early childhood.

Why it matters

Potential benefit: If successful, the approach could reduce the incidence or severity of eczema in newborns by supporting the skin barrier from birth.

How similar studies have gone: Prior research supports vernix' protective properties for the neonatal skin, but primary prevention of atopic dermatitis with this approach is relatively novel and not yet proven in trials.
