FDA Recommends using Physical Sunscreen over Chemical

Dermatologists and Food and drug Administration continue to advise Americans to apply sunscreen. Generally only one in 5 Americans develops cancer. But applying sunscreen reduces the risk. And sunscreen also reduces premature aging, wrinkles and sun spots.

Even though all of us pay little attention to the harm sun does us, we apply sunscreen. And sunscreen, or a sunbed cream (zonnebankcreme) is one of the staple cosmetics everyone uses. So, the FDA proposed a regulation that manufacturers have to provide more data about the safety of certain sunscreen ingredients. And they also requested the details of how much absorbing capacity do these chemicals have, and how they have any effects on the body.

There are two types of sunscreen. One is the physical sunscreen. It sits on the skin and reflects the UV rays. And it contains chemicals like zinc oxide and titanium dioxide. People with sensitive skin must use physical sunscreen. And these sunscreens leave a white residue on skin like applied by cricket players on field. Physical sunscreens are more natural than the next type- Chemical sunscreen.

The chemical sunscreens absorb the UV rays from sun rather than reflecting it. And they have ingredients like Oxybenzone, avobenzone, octisalate, octocrylene, homosalate, octinoxate. These sunscreens do not leave a white residue and are more cosmetically elegant.

The FDA claims that Titanium dioxide and zinc oxide are the safest ingredients for skin. Which means that physical sunscreen is safer. But that does not mean chemical sunscreens are hazardous. It only means that the FDA does not have more information on their level of safety.

If the ingredients on your sunscreen pack concerns you, then check for titanium dioxide and zinc. But if there are other ingredients then you can use a physical sunscreen. You can also use physical barriers like an umbrella, a long sleeve shirt, and a hat. You can use shades for your eyes too. The sun is most powerful in the time frame of 10 am to 2 pm.

It is always better to consult a dermatologist for sunscreen for your skin.

The Scientist as Storyteller: How Steven Quay Makes Complex Medicine Relatable

mm

Published

Scientific discovery often struggles to reach the people it is meant to serve. The distance between research and public understanding can be vast. For most scientists, publishing in peer-reviewed journals is the endpoint. For Dr. Steven Quay, it is only the beginning. His career has been defined not just by what he has discovered, but by how he communicates it. 

Scientific trust today faces growing skepticism and misinformation spreads faster than facts, Quay has embraced a rare role. He is both a scientist and a storyteller. His ability to bridge the technical and the human is what makes his voice resonate across disciplines, institutions, and communities.

Writing as a Lens into the Human Side of Science

One of the clearest examples of Quay’s narrative instinct lies in his writing. He has authored three major books, each rooted in a different part of his life and expertise. Together, they show how a medical researcher can also be an accessible public thinker.

In Stay Safe: A Physician’s Guide to Survive Coronavirus, published June 5, 2020, during the first days of the pandemic, Quay offered plainspoken, evidence-based guidance on protecting oneself and one’s family. It was not framed as a political statement or a policy directive. It was personal and grounded in the daily realities people faced. He wrote it not just as a scientist, but as someone who wanted to help others navigate a frightening time with clarity and calm.

His second book, The Origin of the Virus, tackled a more complex and controversial subject: the question of how SARS-CoV-2 emerged. Rather than speculate, Quay walked readers through the scientific evidence with the kind of transparency that is often lacking in public discourse. The tone was methodical, never alarmist. What set the book apart was its balance, engaging to a lay reader, yet rigorous enough to be taken seriously by professionals.

Then there is A Ride Through Northville, a deeply personal departure from the world of virology and oncology. Here, Quay revisits his childhood in Michigan, capturing the streets, friendships, and quiet moments that shaped him long before he entered a lab. The structure of the book mimics the experience of riding a bike through town, evoking memory not as a chronology, but as a sensory journey. For a scientist whose career has involved high-stakes research and global debates, this book offers a rare window into the reflective, grounded person behind the work.

Speaking Clearly Without Speaking Down

Quay’s communication skill is not limited to the written word. He has also become a frequent guest on health-focused podcasts and a speaker at public science forums. His TEDx talk on breast cancer prevention is one of the most viewed videos on the subject, and for good reason. He does not rely on drama or abstract theory. Instead, he explains mammographic density, hormonal risk, and clinical trial design in a way that makes the science both comprehensible and actionable.

In interviews, Quay has a habit of slowing things down. He avoids jargon unless he defines it. He is comfortable saying, “We don’t know yet,” which, in the realm of public science, is a kind of honesty that builds trust. He often discusses Atossa Therapeutics’ trials in plain terms, describing how experimental drugs like (Z)-endoxifen might help certain patients respond better to treatment. He emphasizes that these are ongoing studies, not marketing pitches, which sets him apart from many biotech executives.

Educating the Public Without Oversimplifying

One of the challenges of public-facing science is resisting the urge to oversimplify. Many well-intentioned scientists flatten complexity to fit the constraints of social media or mainstream news. Quay does not follow that path. He explains mechanisms and hypotheses with nuance, trusting that readers and listeners are capable of understanding more than they are often given credit for.

His social media presence reflects the same philosophy. He shares articles and research updates, but rarely with alarm or bravado. When he comments on current medical debates, he tends to lead with evidence rather than opinion. That steady tone has earned him a following that spans across ideological and professional divides.

During the pandemic, this approach stood out. While others chased headlines, Quay focused on distilling evolving guidance into practical advice. He acknowledged the limits of current knowledge, updated his views as new data emerged, and emphasized science as an iterative process. His voice became one that many people turned to not for certainty, but for clarity.

A Scientist’s Responsibility Beyond the Lab

Quay has often said that science does not exist in isolation. It is part of society. That belief informs why he writes, speaks, and engages in public discourse as actively as he does. He sees the scientist’s role not just as a producer of knowledge, but as a custodian of its meaning.

He has testified before the U.S. Congress and advised the State Department, not as a politician but as a physician-scientist committed to accuracy. In each case, his contribution has been grounded in data but shaped by a recognition of the human implications of policy and research.

This is especially evident in his work on breast cancer. By advocating for better screening tools and more personalized treatments, Quay speaks not only to clinicians and investors but to women facing real fears about their health. He explains the science behind mammographic density and hormonal modulation not just with charts, but with stories about what those risks mean in someone’s life.

Storytelling as a Form of Service

What makes Quay’s communication style compelling is that it never feels performative. He is not branding himself or building a media empire. He is doing what he believes scientists should do: make their work useful.

In every form of his storytelling, from the deeply personal to the technically specific, there is a throughline of responsibility. He understands that science touches people’s lives in ways that go far beyond the lab. For him, that means speaking clearly, writing honestly, and never underestimating the audience.
