I used a sunscreen with oxybenzone before i knew i was pregnant and up to 7 weeks of pregnancy. i also used a different chemical sunscreen without oxybenzone. i had no idea this was an issue until today. did i give my baby hirschprungs disease?

The regular skin surface is a barrier to penetration of over the counter creams and lotions. Those products are not absorbed past the upper surface to the point they would reach the blood. To affect the fetus an agent must achieve a level in the blood high enough to reach the placenta. I would not be concerned about Hirschsprung's or any other defect.

There is so much information to raise anxiety in the newly pregnant couple. The benefits of sunscreen so much outweigh the possible, the potential, and the unnecessarily terrifying. Take good care of yourself; this will give your baby the best possible odds. Best wishes to your family.
