Topical retinoids during pregnancy?

I am 16 weeks pregnant now, but during the early stages, I had acne and used a third-generation moisturizer that contains retinoids on my face for about two months.
Later, I heard that it could affect the baby and cause birth defects, so I stopped using it at 13 weeks.
Will this affect my baby? What is the likelihood of that? Can regular ultrasounds detect any issues? Would a high-level ultrasound be more accurate? Please let me know.
Thank you!

Dear netizens: Hello! Most topical medications for skin treatment are absorbed into the body in very small amounts.
Currently, there are no reports or warnings in obstetric clinical practice indicating that moisturizing creams cause fetal malformations, so the likelihood of affecting the baby should be minimal.
Of course, the probability of detecting fetal abnormalities with high-level ultrasound is higher than with standard ultrasound examinations.

The use of topical retinoids during pregnancy, particularly those containing retinoic acid (commonly referred to as A acid), raises significant concerns due to their potential teratogenic effects. Retinoids are a class of compounds derived from vitamin A and are widely used in dermatology for treating acne and other skin conditions. However, their safety profile during pregnancy is a critical consideration for expectant mothers.

Firstly, it is essential to understand that retinoids are classified as Category X drugs by the FDA when taken orally, indicating that they have been shown to cause birth defects in humans. While topical retinoids are generally considered to have a lower risk compared to their oral counterparts, there is still a potential for systemic absorption, especially when used over large areas of the skin or in high concentrations. The concern is that even minimal systemic absorption could lead to adverse effects on fetal development.

In your case, you mentioned using a third-generation topical retinoid for about two months during the early stages of your pregnancy, specifically until the 13th week. The critical period for organogenesis, where the major organs and structures of the fetus are formed, occurs during the first trimester (weeks 1-12). Therefore, the use of retinoids during this time is particularly concerning. However, since you ceased using the product at the 13th week, the risk of teratogenic effects may be reduced, but it is not entirely eliminated.

Regarding the likelihood of your baby being affected, it is challenging to provide a definitive answer. The risk of teratogenic effects from topical retinoids is not as well-studied as that of oral retinoids, and many factors can influence the outcome, including the specific formulation, the amount used, and individual variations in absorption and metabolism. While some studies suggest that the risk is low, it is essential to approach this situation with caution.

As for prenatal screening, standard ultrasounds typically performed during pregnancy can help identify some structural abnormalities, but they may not detect all potential issues, especially those related to subtle developmental problems that may arise from teratogenic exposure. High-resolution ultrasounds or specialized imaging techniques may provide more detailed information, but they are not guaranteed to reveal all potential concerns.

It is crucial to maintain open communication with your healthcare provider throughout your pregnancy. They can offer personalized advice based on your specific situation and may recommend additional monitoring or testing if deemed necessary. If you have concerns about the potential effects of the topical retinoid on your baby, discussing these with your obstetrician or a maternal-fetal medicine specialist can provide you with reassurance and guidance.

In summary, while the use of topical retinoids during early pregnancy is concerning, the actual risk of harm to your baby may vary. It is essential to continue monitoring your pregnancy and to consult with your healthcare provider regarding any concerns you may have. They can help you navigate this situation and ensure the best possible outcomes for both you and your baby.
