Should You Be Worried About Benzene in Your Skin Care Products?
Benzene is a known carcinogen, and although no safe level of benzene exposure is considered acceptable, the FDA permits a concentration of up to 2 parts per million (ppm) in certain products. However, Valisure's testing showed benzene levels far exceeded this threshold in several products.
How Does Benzene End Up in Skin Care Products?
Benzene is often found in products due to the breakdown of benzoyl peroxide (BPO), a common ingredient in over-the-counter acne treatments. Benzoyl peroxide is effective at treating acne, but it can degrade into benzene under certain conditions. Specifically, when products containing BPO are exposed to heat -- like the kind of warmth you might find in a bathroom -- more benzene can accumulate, increasing your risk of exposure.
Valisure tested seven different products containing benzoyl peroxide, including some popular over-the-counter creams and cleansers. Benzene was detected in all of them, and after being kept at temperatures ranging from 98.6 F to 158 F. It found that the levels of benzene increased to several times the FDA's allowable concentration.
Given that these products are widely used in the treatment of acne, this discovery is raising significant concerns. The question is: What does this mean for your health?
Should You Stop Using These Products?
Many of my patients have chosen to stop using benzoyl peroxide products altogether after hearing about these findings. However, there is some evidence suggesting that you might not need to be overly concerned -- at least not to the extent of stopping their use completely.
One study examined the serum levels of benzene in people who used benzoyl peroxide-containing products and compared them with people who had no exposure.
The study found no significant increase in the risk of lymphoma, leukemia, or harmful conditions, which are the primary health risks associated with benzene exposure. This suggests that, while benzene is present in these products, the actual risk may be minimal.
What Does This Mean for You?
While the presence of benzene in skin care products is concerning, it's important to put these findings into context. The FDA allows trace amounts of benzene in certain products, and the levels found in many of these acne treatments — although elevated under specific conditions — may not necessarily translate into a significant health risk for most people.
However, if you're still concerned, there are a few things you can do:
Be mindful of storage conditions: Avoid storing your skin care products in hot, humid places like your bathroom. Keeping these products at room temperature may help minimize benzene buildup.
Look for alternatives: If you're uncomfortable using products containing benzoyl peroxide, there are many other acne treatments available, including options with different active ingredients, such as salicylic acid, sulfur, or retinoids.
Monitor updates and regulations: Keep an eye on new studies and reports. As more research is done on benzene exposure from skin care products, additional regulations or recommendations may be issued.
The discovery of benzene in skin care products, particularly those containing benzoyl peroxide, raises important concerns. While the evidence on benzene's potential health risks in this context is not definitive, it is clear that more research is needed. For now, the best course of action may be to make informed choices based on your comfort level and to keep abreast of new studies and regulatory updates.
If you're unsure, consulting your dermatologist for personalized advice is always a good option.
Ultimately, the goal is to use products that not only treat skin concerns effectively but also keep your health and safety in mind. Stay informed and make decisions that best align with your skin and overall well-being.

Foreign medical residents fill critical positions at US hospitals, but are running into visa issues
Some hospitals in the U.S. are without essential staff because international doctors who were set to start their medical training this week were delayed by the Trump administration's travel and visa restrictions. It's unclear exactly how many foreign medical residents were unable to start their assignments, but six medical residents interviewed by The Associated Press say they've undergone years of training and work only to be stopped at the finish line by what is usually a procedural step. 'I don't want to give up,' said a permanent Canadian resident who matched to the University of Pittsburgh Medical Center Harrisburg but had her visa denied because she is a citizen of Afghanistan. She requested to remain anonymous for fear of reprisal. 'But the situation also seems so helpless.' Initially, the medical community was worried that hundreds of positions — many in hospitals in low-income or rural areas of the U.S. — could be affected. The pause on interviews for J-1 visas for approved work or study-related programs was lifted in mid-June. The national nonprofit that facilitates the residency match process said the visa situation is resolving, but it will take weeks to know with confidence how many medical residents have had the start of their careers derailed because they got their visa too late or were blocked by President Donald Trump's travel ban on 12 countries, according to people who coordinate the residents' training. Four foreign medical residents told the AP that U.S. embassies have been slow to open up interview slots — and some have not opened any. 'You lose out on the time you could have used to treat patients,' said one resident from Pakistan, who matched to an internal medicine program in Massachusetts and requested to remain anonymous for fear of reprisal. Thousands of foreign medical residents fill gaps in U.S. hospitals The U.S. is projected to face a physician shortage in the next 11 years, per the Association of American Medical Colleges, and foreign medical residents fill critical gaps in the health care system. More than 6,600 foreign-born international medical residents matched into U.S. programs in 2025 — the highest on record — and another 300 filled positions that were vacant after the match process was complete. Not all of those residents were affected by visa issues or the travel ban on foreign nationals from countries including Afghanistan, Haiti and Sudan. International medical graduates often take jobs in places where U.S. medical trainees tend not to go, said Donna Lamb, president of the National Resident Matching Program. 'It's not just that they're coming in and they want to work in big, flashy centers on the coast,' Lamb said. 'They're truly providing health care for all of America.' Foreign medical residents work in specialties that U.S. applicants aren't as eager to apply to. For example, international candidates make up almost 40% of residents in internal medicine, which specializes in the prevention and treatment of chronic conditions like diabetes and heart disease. 'The residents are the backbone of the entire hospital,' said Dr. Zaid Alrashid from Brookdale University Hospital and Medical Center in New York, which has medical residents from almost every continent. Most received their visas prior to the pause but a few were caught up in delays. Two residents from India who spoke on condition of anonymity have not been able to get an appointment at any U.S. embassies there despite the J-1 visa pause being lifted. Another resident from Egypt just secured a visa appointment for mid-August but is worried her program may not be willing to wait for her. She's already paid her security deposit for an apartment in Texas to live during her residency. "I don't know when this situation will be resolved,' said the resident, who spoke on condition of anonymity, adding she hasn't been eating or sleeping well. Hospitals waiting for residents to arrive In California, leaders at two graduate medical education programs said they have a small number of residents caught up in J-1 visa delays. Both spoke on condition of anonymity due to concerns for the doctors who are still trying to get visas. A residency leader at one large health care system said two doctors in its 150-resident program are delayed, adding they could start late or defer to next year. A 135-person program at a California public health system told the AP that one resident has yet to arrive, though he was finally scheduled for a visa interview. 'We are not going to breathe easy until he's here in our hospital,' the second leader said. As of Wednesday, Lamb's matching program had received fewer than 20 requests to defer or cancel residency contracts. Worried about losing their spots if they defer, many foreign medical residents may keep trying to get to the U.S. and start their residencies late, said Dr. Sabesan Karuppiah, a past member of the American Medical Association's International Medical Graduates Governing Council and former director of a large residency program. Some hospitals may struggle at this point to replace the residents who don't make it, leaving fewer people to care for the same number of patients, said Kimberly Pierce Burke, executive director of the Alliance of Independent Academic Medical Centers. Foreign medical trainees who've made it into the U.S. remain on edge about their situations, Karuppiah said. 'I can tell you the word on the street is: 'Do not leave the country,'' he said, adding that people are missing out on important events, seeing sick parents or even getting married. 'Everybody's scared to just leave, not knowing what's going to happen.' —- The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.

Rural hospitals brace for financial hits or even closure under Republicans' $1 trillion Medicaid cut
OMAHA, Neb. — Tyler Sherman, a nurse at a rural Nebraska hospital, is used to the area's aging farmers delaying care until they end up in his emergency room. Now, with Congress planning around $1 trillion in Medicaid cuts over 10 years, he fears those farmers and the more than 3,000 residents of Webster County could lose not just the ER, but also the clinic and nursing home tied to the hospital.
