During pregnancy, a combination of factors can create a pregnancy glow. Greater blood volume brings more blood to vessels, resulting in skin that looks flushed. Changes in hormone levels might also cause the skin glands on the face to secrete more oil (sebum), which can make skin look slightly shinier.
The factors that contribute to pregnancy glow can have a downside, however. Fluctuating hormone levels during pregnancy might make you more prone to acne.
Enjoy your pregnancy glow. If you have any questions or concerns, contact your health care provider.
