Lately, I’ve had more and more clients ask me if sunscreen causes cancer. With all of the headlines and social media posts circulating, it’s completely understandable to have questions.
After spending nearly 15 years working in a dermatology clinic and helping clients protect and improve their skin every day, I can confidently tell you this:
The damage caused by unprotected sun exposure is real, well documented, and far more concerning than the fears surrounding sunscreen.
Skin cancer is the most common cancer in the United States, and years of cumulative UV exposure significantly increase the risk of developing basal cell carcinoma, squamous cell carcinoma, and melanoma. Beyond cancer, ultraviolet (UV) radiation is responsible for up to 90% of visible skin aging, including wrinkles, brown spots, broken capillaries, and loss of elasticity. Consistent daily sun protection is one of the most effective anti-aging treatments available.
Understanding the Two Types of Sunscreen
There are two primary categories of sunscreen:
Mineral (Physical) Sunscreens
Active ingredients include Zinc Oxide and Titanium Dioxide. These ingredients sit on the skin and help protect against harmful UVA and UVB rays. They begin working immediately after application and are an excellent option for sensitive skin, children, and anyone looking to avoid traditional chemical UV filters.
Current FDA reviews have found zinc oxide and titanium dioxide to be the sunscreen ingredients with sufficient evidence to be considered Generally Recognized as Safe and Effective (GRASE). Importantly, the FDA has not concluded that other sunscreen ingredients are unsafe. It has simply requested additional safety data for several chemical filters as sunscreen use has become more widespread. (U.S. Food and Drug Administration)
Chemical Sunscreens
These contain ingredients that absorb UV energy before it damages the skin. Many provide excellent broad-spectrum protection and have elegant, lightweight textures. Some chemical sunscreen ingredients have been detected in the bloodstream after use. While this has raised understandable questions, absorption alone does not mean these ingredients are harmful. Research is ongoing, and health organizations continue to recommend sunscreen as part of a comprehensive sun protection strategy because the proven benefits far outweigh any theoretical risks.

Why I Often Recommend Mineral Sunscreens
For my clients, I frequently recommend high-quality mineral sunscreens because they provide outstanding protection while giving peace of mind to those concerned about ingredient safety. I also recommend mineral sunscreen for anyone who is prone to rosacea, acne, or any other inflammatory condition.
If you tried a mineral sunscreen years ago and disliked the thick white cast, you’re not alone. Thankfully, sunscreen technology has come a long way.
Many premium mineral sunscreens now use highly refined, micronized mineral particles that blend beautifully into the skin with little to no white residue. These formulations tend to feel lighter, wear better under makeup, and are far more cosmetically elegant. They often come with a higher price tag because creating these sophisticated textures requires more advanced manufacturing and formulation techniques, but they are well worth the investment.
What About Vitamin D?
A common concern I hear is whether wearing sunscreen prevents your body from getting enough vitamin D. The good news is that you can still produce vitamin D while wearing sunscreen. In real life, sunscreen is rarely applied perfectly or in thick enough layers to completely block UVB rays, which are responsible for vitamin D production.
Additionally, most people receive incidental sun exposure throughout the day, such as walking to their car or running errands, which is often enough to support vitamin D levels. For those who are still concerned, vitamin D can also be safely obtained through diet and supplements without increasing your risk of sun damage.
It is important to remember that the risks of unprotected sun exposure, including skin cancer and premature aging, far outweigh the minimal impact sunscreen may have on vitamin D production.
Sunscreen Is Just One Part of Sun Protection
No sunscreen is perfect on its own. The best protection comes from combining sunscreen with other healthy habits.
Wear sun-protective clothing and hats when possible. Wear a broad-spectrum SPF 30 or higher every day. Reapply every two hours when outdoors and after swimming or sweating.
My Final Thoughts
As someone who has watched countless patients undergo skin cancer surgeries and treatment during my years in dermatology, I have seen firsthand what chronic sun damage can do.
While research on sunscreen ingredients continues, as it should, the scientific evidence overwhelmingly supports protecting your skin from ultraviolet radiation. The goal is not to create fear around sunscreen. It is about choosing a product you will actually enjoy wearing every single day.
If you have questions about which sunscreen is right for your skin type, lifestyle, or concerns, I am always happy to help. Whether you are looking for a lightweight everyday SPF, something that layers beautifully under makeup, or a mineral sunscreen that does not leave a white cast, I can recommend options that fit your needs.
Here’s to healthy, protected, glowing skin all year long.
