Facial profile of a foetus in the womb. Towards the end of the second trimester (28 weeks or 6 months), facial features of the foetus become more apparent. The eyelids develop, and hair, eyelashes, and eyebrows begin to grow. By week 32, the foetus is sensitive to light and shuts its eyes when sleeping. At week 35, it has a full head of fine hair. The addition of subcutaneous body fat in the last trimester rounds out facial features and protects the baby from heat loss after birth.
