ABSTRACT
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.
