Antiperspirants for breastfeeding?


Hello Doctor, I am a breastfeeding mother and have been breastfeeding for 10 months.
I have been using an antiperspirant under my arms, but I recently came across an article stating that it could be passed to my baby through breast milk.
I am very worried and feel guilty.
Here are the ingredients: Aqua (water), PPG-15 Stearyl Ether, PPG-15 Stearate, Steareth-21, Parfum (fragrance), Persea gratissima (avocado oil), Magnesium DNA, Aluminum silicate, Trisodium EDTA, Butylene Glycol, Benzophenone-4.
Please help me with your answer.

I believe that the amount of legally topical medications absorbed through the skin into the lymphatic and circulatory systems, and subsequently secreted into breast milk for the baby, is negligible and unlikely to affect the baby.
If there are still concerns, it is advisable to clean the underarm area and the nipple-areola complex before breastfeeding or pumping.
As long as the baby does not directly ingest it, there should be no issue.

When it comes to the safety of antiperspirants for breastfeeding mothers, it is understandable to have concerns about the potential effects on your baby. The ingredients in antiperspirants can vary widely, but many contain aluminum compounds, fragrances, and other chemicals that may raise questions about their safety during breastfeeding.

First and foremost, it's important to note that the skin acts as a barrier, and while some substances can be absorbed through the skin, the amount that enters the bloodstream and subsequently into breast milk is typically very low. According to current research, there is no substantial evidence to suggest that the use of antiperspirants by breastfeeding mothers poses a significant risk to infants. The American Academy of Pediatrics (AAP) has not issued specific guidelines against the use of antiperspirants during breastfeeding.

Looking at the ingredients you've listed, let's break down some of the key components:
1. Aluminum Compounds: These are commonly used in antiperspirants to block sweat glands. While there have been concerns about aluminum's potential link to breast cancer and other health issues, studies have not conclusively proven that aluminum in antiperspirants is harmful. The amount that could potentially be transferred to breast milk is minimal.

2. Fragrances: These can sometimes cause allergic reactions or sensitivities in both mothers and infants. If you notice any adverse reactions in your baby, it might be worth considering a fragrance-free option.

3. Moisturizers and Emollients: Ingredients like avocado oil (Persea gratissima) and butylene glycol are generally considered safe and are often included for their skin-conditioning properties. They are unlikely to pose a risk to breastfeeding infants.

4. Preservatives and Stabilizers: Ingredients like Trisodium EDTA and Benzophenone-4 are used to stabilize formulations and protect against degradation. While they are generally recognized as safe in cosmetic products, their long-term effects on breastfeeding are not extensively studied.

In summary, while it is always wise to be cautious about what you apply to your skin while breastfeeding, the current consensus in the medical community suggests that using antiperspirants in moderation is unlikely to harm your baby. If you have specific concerns or if your baby shows any signs of sensitivity, it may be beneficial to consult with a pediatrician or a dermatologist. They can provide personalized advice based on your situation.

Additionally, if you feel uncomfortable using conventional antiperspirants, consider exploring natural alternatives that do not contain aluminum or synthetic fragrances. Many breastfeeding mothers opt for these products to minimize any potential risks.

Ultimately, the decision to continue using antiperspirants should be based on your comfort level and any reactions you observe in your baby. Remember, maintaining good hygiene is important, and if you find that antiperspirants help you feel more comfortable, it is generally safe to continue their use while breastfeeding.
