Which ingredient should be avoided by pregnant individuals due to potential risks?

Retinoids are derivatives of Vitamin A and are widely known for their effectiveness in promoting cell turnover, reducing fine lines, and managing acne. However, during pregnancy, there are significant concerns surrounding the use of retinoids. Research suggests that excessive levels of Vitamin A can lead to congenital disabilities or other serious health issues for the developing fetus. As a result, both oral retinoids, like isotretinoin, and topical formulations are generally advised against during pregnancy.

In contrast, ingredients like peptides, Vitamin C, and hyaluronic acid are considered safe for use during pregnancy. These components provide beneficial effects such as hydration, antioxidant protection, and improving skin texture without posing risks to fetal health. Therefore, retinoids stand out as the key ingredient that should be avoided by pregnant individuals, emphasizing the importance of being cautious with skincare products during this critical time.
