WHAT IS BEMT SUNSCREEN?
Meet BEMT (bemotrizinol), a new sunscreen active ingredient in the U.S. that delivers durable, broad-spectrum UVA + UVB protection.
WHAT IS BEMT?
BEMT, short for bemotrizinol, is a sunscreen active ingredient that helps protect skin from both UVA and UVB radiation.
You may not recognize the name yet, but BEMT is likely to become much more familiar to American sunscreen users. In 2026, the U.S. Food and Drug Administration added bemotrizinol to the list of permitted sunscreen active ingredients, making it the first new sunscreen active ingredient added in the United States in decades.
BEMT has already been used in sunscreens in Europe and other countries around the world. Its arrival in the U.S. gives sunscreen formulators another tool for developing modern broad-spectrum sun protection.
WHY DOES BEMT MATTER?
Sunscreen isn't only about preventing a visible sunburn. Effective sun protection needs to address different types of ultraviolet radiation.
UVB rays are primarily associated with sunburn, while UVA rays penetrate deeper into the skin and contribute to premature skin aging and long-term skin damage.
That's why broad-spectrum protection matters. BEMT provides UV protection across both the UVA and UVB ranges, making it useful in broad-spectrum sunscreen formulations.
For people who spend hours outside — whether you're playing golf, tennis, running, training, swimming or simply enjoying the outdoors — the technology behind your sunscreen matters.
WHAT DOES PHOTOSTABLE SUNSCREEN MEAN?
One of the most important characteristics of BEMT is its photostability.
That sounds technical, but the idea is actually pretty simple. Sunscreen ingredients are exposed to intense ultraviolet radiation whenever you're outside. A photostable UV filter is able to remain stable when exposed to sunlight.
BEMT is considered highly photostable, which makes it particularly useful when developing sunscreen designed for broad-spectrum UV protection.
Photostability does not mean you can apply sunscreen once and forget about it. Sunscreen still needs to be applied and reapplied according to the directions on the product, particularly when you're swimming, sweating or spending extended periods outdoors.
BEMT AND PERFORMANCE SUNSCREEN
At WearSPF, we think about sunscreen from the perspective of people who actually spend hours performing outside.
Think about what your sunscreen experiences during 18 holes of golf, a long tennis match, a morning run or an afternoon on the water: hours of sunlight, increasing UV exposure, heat, sweat, water, friction and repeated movement.
That's what we mean by Performance Sunscreen.
It starts with broad-spectrum sun protection, but performance also means thinking about water resistance, wearability, reapplication and the sunscreen technology behind the formula.
BEMT represents another advancement available to sunscreen formulators developing products around those demands.
IS BEMT A MINERAL SUNSCREEN INGREDIENT?
No. BEMT is an organic sunscreen active ingredient, sometimes referred to by consumers as a chemical sunscreen filter.
Mineral sunscreens use active ingredients such as zinc oxide or titanium dioxide. BEMT works differently, but it can also provide protection across UVA and UVB wavelengths.
One isn't automatically right for everyone. Some people prefer mineral sunscreen, while others prefer non-mineral or hybrid sunscreen formulas.
What matters most is choosing broad-spectrum protection appropriate for your activity and using it correctly.
BEMT VS. ZINC OXIDE: WHAT'S THE DIFFERENCE?
Both BEMT and zinc oxide can be used in sunscreens designed to provide broad-spectrum UVA and UVB protection, but they are different types of sunscreen active ingredients.
Zinc oxide is a mineral sunscreen active ingredient. BEMT is an organic UV filter.
Rather than focusing on whether one individual ingredient is "better," it's useful to look at the sunscreen as a complete formula. SPF, broad-spectrum protection, water resistance, application, feel and how you plan to use the product all matter.
WHY SUNSCREEN TECHNOLOGY MATTERS FOR ATHLETES
Athletes ask a lot from their equipment. Sunscreen should be no different.
A golfer may spend four or five hours on the course. A tennis player can compete through the strongest UV hours of the day. Runners, swimmers and outdoor athletes may deal with a combination of direct sunlight, sweat, water and heat.
When choosing sunscreen for sports and extended outdoor activity, look for:
- Broad-Spectrum Protection: Protection against both UVA and UVB radiation.
- SPF: Choose an SPF appropriate for your expected sun exposure and activity.
- Water Resistance: Particularly important when swimming, sweating or exercising outdoors.
- Wearability: Sunscreen only works when you actually use enough of it.
- Easy Reapplication: Outdoor athletes need to be able to reapply protection throughout the day.
Modern UV filters like BEMT give sunscreen formulators another option when building products around these performance demands.
