  • During the second trimester, around the 13th week, your baby’s skin will look thin and transparent. As the week’s progress, the skin will begin to thicken (1).
  • During the 19th week, a cheesy coating known as vernix caseosa appears to cover the body of the fetus. This coating works as a protective layer against chapping, abrasions and hardening as a result of being exposed to the amniotic fluid. This coating is shed right before birth (2).
  • About 24 weeks into your pregnancy, your precious one’s skin looks pinkish-red in color. It gets that color because of the visible blood vessels below the skin. The skin also becomes translucent (3).
  • During the end of the second trimester, at 27 weeks, your baby starts gaining fat giving the skin a smoother appearance. Now you know where they get their baby-soft skin!

Knowing about all the changes that are taking place in your womb will make the experience all the more magical and real at the same time. Here’s wishing you a healthy and happy pregnancy!
