Can pregnant women use antiperspirants?


There is a family history of bromhidrosis, and I am also troubled by it.
I have been using antiperspirants for a long time, specifically "Youdafen" antiperspirant two days a week.
I am planning to become pregnant and would like to know if using "Youdafen" will have any effects on the pregnant woman, the fetus, or postpartum breastfeeding (e.g., will the fetus be unhealthy)? The active ingredient in Youdafen is Aluminium chloride 6H2O at 20% w/v, with other components including PEG-12 Dimethicone at 1% v/v and Alcohol denat.
to 100% v/v.

Hello, please refer to the instructions and usage guidelines for antiperspirants, which should include any contraindications or precautions.
You may also bring the antiperspirant with you to the obstetrics and gynecology clinic for preconception counseling.
Thank you.

When it comes to the safety of using antiperspirants during pregnancy, particularly products like "Youdifen" that contain aluminum chloride, it's essential to consider both the ingredients and the potential risks involved.
Aluminum chloride is a common active ingredient in many antiperspirants. It works by temporarily blocking the sweat glands, thereby reducing perspiration. The concern surrounding aluminum compounds has been a topic of debate for many years, especially regarding their potential link to breast cancer and Alzheimer's disease. However, current research has not conclusively proven these claims, and regulatory bodies like the U.S. Food and Drug Administration (FDA) and the American College of Obstetricians and Gynecologists (ACOG) have not issued warnings against the use of aluminum-containing antiperspirants during pregnancy.

The FDA classifies aluminum chloride as generally recognized as safe (GRAS) when used in cosmetic products, including antiperspirants. While there is limited research specifically addressing the effects of aluminum chloride on pregnant women and their fetuses, the consensus among health professionals is that the amount absorbed through the skin from antiperspirants is minimal and unlikely to pose a significant risk.

In terms of the other ingredients in "Youdifen," such as PEG-12 Dimethicone and denatured alcohol, these are also generally considered safe for topical use during pregnancy. PEG compounds are often used in cosmetics for their emulsifying properties, and while there are some concerns about their potential to irritate the skin, they do not pose a significant risk to fetal health. Denatured alcohol is used as a solvent and is typically safe in small amounts when applied topically.

It's important to note that while using antiperspirants is generally considered safe during pregnancy, individual reactions can vary. Some pregnant women may experience increased skin sensitivity or irritation due to hormonal changes, which could make the use of certain products uncomfortable. If you notice any adverse reactions, it would be wise to discontinue use and consult with your healthcare provider.

Regarding breastfeeding, there is no evidence to suggest that the use of aluminum-containing antiperspirants would adversely affect breast milk or the nursing infant. The amount of aluminum that could potentially enter the bloodstream and subsequently breast milk is negligible.

In conclusion, using "Youdifen" or similar antiperspirants during pregnancy is generally considered safe based on current evidence. However, if you have specific concerns or a family history of conditions that may be exacerbated by aluminum exposure, it would be prudent to discuss these with your healthcare provider. They can provide personalized advice based on your health history and any potential risks. Additionally, if you are planning to conceive, consider exploring alternative methods for managing body odor, such as natural deodorants that do not contain aluminum or other synthetic ingredients, as these may provide peace of mind during your pregnancy journey.
