New Study Raises More Concerns About Benzoyl Peroxide Degrading Into Benzene

Concerns Surround Safety of Benzoyl Peroxide in Acne-Fighting Skin-Care Products

A new study published in the Journal of Investigative Dermatology on Monday, October 7, is reigniting concerns about the safety of benzoyl peroxide in acne-fighting skin-care products.

A Well-Known Skin-Care Ingredient with a Dark Side

You’re probably no stranger to benzoyl peroxide; it’s a famed skin-care ingredient known for its acne-fighting properties. And this isn’t the first time research has raised red flags about its potential to degrade into benzene—a known carcinogen—when exposed to elevated temperatures and UV light.

Latest Research Finds Worrying Results

The latest research tested 111 over-the-counter benzoyl peroxide acne products and found that 34% had benzene levels that surpassed the FDA’s 2 ppm safety limit.

Earlier Research Confirmation

These findings mirror an earlier study published in March study published in March. As reported by Dermatology Times, the March study’s findings showed that benzene levels spiked “when the acne products were tested at higher temperatures that were designed to replicate how the products can break down over time.” The latest study confirms that both heat and UV exposure accelerate benzene formation—so where do we go from here?

A Call to Action from a Leading Dermatologist

Christopher Bunick, MD, PhD, associate professor of dermatology at Yale University School of Medicine, and one of the study’s authors, explains: “If you’re going to continue to use benzoyl peroxide-containing products, then what I’m doing is asking patients to store their benzoyl peroxide-containing product in the refrigerator. I think it’s a very simple method to minimize the decomposition of the benzoyl peroxide and mitigate the levels of benzene.”

More Research Needed, But Already Worrying Implications

In NewBeauty’s previous reporting on the March findings, some dermatologists called for more data, while others advised proceeding with caution. Omaha, NE dermatologist Joel Schlessinger, MD, stressed that “even minimal amounts of benzene pose risks.” He added, “Given these findings, it’s clear that current guidelines may need revision to reflect emerging data and better safeguard public health.” Our advice is to stay cautious and informed as this ongoing investigation continues to unfold.

FAQs

Q: What is benzoyl peroxide?

Benzoyl peroxide is a well-known skin-care ingredient used in acne treatments to help reduce acne and heal skin.

Q: What is benzene?

Benzene is a known carcinogen that can cause cancer. High levels of benzene have been linked to an increased risk of leukemia and other blood cancers.

Q: How did benzoyl peroxide degrade into benzene?

Benzoyl peroxide can degrade into benzene when exposed to elevated temperatures and UV light, a process known as photochemical degradation.

Q: What is the recommended way to store benzoyl peroxide products?

According to Dr. Christopher Bunick, patients should store their benzoyl peroxide-containing products in the refrigerator to minimize the decomposition of the benzoyl peroxide and mitigate the levels of benzene.

Q: What can I do to minimize my exposure to benzene?

storing your benzoyl peroxide products in the refrigerator is a simple method to minimize the decomposition of the benzoyl peroxide and mitigate the levels of benzene. Additionally, you can consider using alternative acne treatments that do not contain benzoyl peroxide.

Q: Can I still use benzoyl peroxide products?

Yes, you can still use benzoyl peroxide products, but it is essential to follow the recommended storage and usage guidelines to minimize the risk of benzene exposure. Consult with your dermatologist or healthcare provider for personalized advice on using benzoyl peroxide products.

Conclusion

A new study published in the Journal of Investigative Dermatology has raised concerns about the safety of benzoyl peroxide in acne-fighting skin-care products. With benzoyl peroxide being a well-known skin-care ingredient, this study highlights the importance of being cautious and informed when using these products. As the investigation continues, it is crucial to stay updated on the latest research and guidelines to ensure public health and safety.
