Our skin experiences a variety of changes during pregnancy. In order to keep our skin healthy throughout pregnancy, our skin care routine could require some changes of its own. Medical News Today shares that while most over-the-counter products are safe during pregnancy, it is a good idea to avoid certain ingredients, such as retinoids, hydroquinone, and phthalates. A good rule of thumb is to always check labels, and as the American College of Obstetricians and Gynecologists recommends, always talk with your healthcare provider before applying anything to your skin. Some creams, lotions, and gels contain these harmful ingredients.
