As a distinguished figure in the realm of clean beauty and skincare, I can provide you with information about polyglutamic acid and its safety during pregnancy. Polyglutamic acid (PGA) is a water-soluble peptide derived from fermented soybeans. It is known for its hydrating and moisturizing properties, making it a popular ingredient in skincare products.

While there is limited research specifically focusing on the safety of PGA during pregnancy, it is generally considered safe for topical use. PGA is not known to be absorbed systemically into the bloodstream, so the risk of it reaching the developing fetus is minimal.

However, it is always recommended to consult with a healthcare professional, such as an obstetrician or dermatologist, before introducing any new skincare products during pregnancy. They can provide personalized advice based on your specific circumstances and medical history.

Additionally, it is worth noting that everyone's skin is unique, and some individuals may have sensitivities or allergies to certain ingredients. It is always a good idea to perform a patch test before using any new skincare product, including those containing polyglutamic acid, to ensure you do not have any adverse reactions.

Overall, while polyglutamic acid is generally considered safe for topical use during pregnancy, it is best to consult with a healthcare professional for personalized advice.
