I've read a few different places that rubbing the vernix into the baby right after birth is beneficial to his/her skin. Is this true? What are the benefits exactly?

OBJECTIVES: Skin cleansing is a complex process involving endogenous and exogenous mechanisms. This study examines the role of vernix caseosa in the process of skin cleansing in the perinatal period. METHODS: Vernix was evaluated as an exogenously applied skin cleanser using digitized image analysis which quantified residual carbon particles following a standardized cleansing assay. In addition, the detachment of vernix from human cadaveric skin and Gore-Tex supports was investigated following timed exposures to a variety of commonly used commercial surfactants. Detachment was quantified spectrophotometrically as increased turbidity at 650 nm. RESULTS: Image analysis showed that exogenous application of vernix exhibited a cleansing capability comparable or superior to standard skin cleansers. Dose-dependent increases in solution turbidity (vernix detachment) were seen following exposure of vernix-covered Gore-Tex vehicles to sodium laureth sulfate, sodium lauryl sulfate, and cocamidopropyl betaine solutions. Similar results were seen with cadaveric skin. CONCLUSIONS: These results demonstrate a role for vernix caseosa as a skin cleanser. Previous views of vernix as a soil or skin contaminant at birth need to be reevaluated.
|Is vernix caseosa a protective material to the newborn? A biochemical approach.

Twenty random samples of vernix caseosa were collected from immediately born neonates, in Jamahiriya Hospital, Benghazi. Biochemical studies of these samples revealed presence of lipids (62.5%), proteins (36%) and carbohydrate (1.5%). Also we could observe inhibition of staph. aureus and klebsiella growth on nutrient agar by this vernix. This observation could be explained either by its higher asparagine content or by its elevated lipid component. In addition tripalmitin was found to be the major lipid constituent, responsible for its hydrophobic property. So we recommend leaving this vernix layer on newborn skin until spontaneous drying.
