Lipids in forehead vernix from newborn infants.
Neutral lipids in forehead vernix from newborn infants of various gestations were analysed by gas chromatography. Vernix collected from pre-term (less than 37 weeks) infants differed markedly from that collected from near-term (less than or equal to 37 weeks) infants. The principle difference was a increase in the content of squalene relative to other lipids in vernix from near-term infants. This change indicated a surge in fetal sebaceous gland function at about 37 weeks gestation.
