Concerns have been raised over the use of benzoyl peroxide, a common ingredient in over-the-counter acne treatments. It is efficient against acne-causing bacteria, but high heat may break it down into benzene, a carcinogen. This page discusses benzoyl peroxide dispute, expert advice, and acne treatment alternatives.
The Double-Edged Sword of Benzoyl Peroxide
Benzoyl peroxide destroys acne-causing bacteria as a topical antiseptic. Extreme temperatures could doom it. Benzoyl peroxide can convert into cancer-causing benzene under these conditions.
FDA-approved acne treatments contain 2.5%–10% benzoyl peroxide. Dermatologists prescribe 2.5% to 5% for facial acne and 5% to 10% for torso acne.
Valisure Study: Concerning?
A recent examination by Valisure, an independent consumer goods and pharmaceutical medication safety laboratory, highlighted concerns. After heating benzoyl peroxide acne treatments to 158 degrees Fahrenheit, researchers identified benzene. Even goods with a lower 2.5% concentration had high benzene levels at high temperatures.
Dermatologists Advise Caution But Not Panic
Experts warn against overreacting to Valisure’s findings. Critical details that could affect the study’s outcomes are missing. The products’ purchase date, storage circumstances until testing, and most significantly, the possibility for benzene production at room temperature—a more realistic scenario for consumers—are unknown.
Dermatologists advise against discarding benzoyl peroxide products due to inadequate data. Benzoyl peroxide has been a safe and efficient acne therapy. For significant breakdown into benzene, persistent high temperature exposure is likely required.
Safe Storage and Treatment Alternatives
Here are some essential steps:
- Maintain Proper Storage: Store acne products at room temperature or refrigerate for safety.
- Toss Expired or Overheated Products: Make sure to check expiration dates and discard products that have been left in a hot car.
- Consider Other Treatments: If benzoyl peroxide worries you, ask your doctor about other acne treatments. Salicylic acid, retinoids, sulfur-containing compounds, and azelaic acid work. For severe situations, your dermatologist may prescribe medication.
The Future: Regulatory Changes and Consumer Health
While a major benzoyl peroxide recall is unlikely, stricter storage temperature labeling is anticipated. Manufacturers may also be scrutinized for effective transit temperature control to prevent product degradation.
Bottom Line: Knowledge Is Power
Despite current concerns, benzoyl peroxide can treat acne. Safe storage and dermatologist advice can help you control acne safely. Remember, your dermatologist can evaluate your needs and propose the best treatment, including benzoyl peroxide with other medications or alternative options.
