Bemotrizinol is now permitted
in U.S. sunscreens—what shoppers should know

On June 9, 2026, the U.S. Food and Drug Administration added bemotrizinol—also called BEMT—to the permitted active ingredients for over-the-counter sunscreens. The final order took effect August 9, 2026, making this the first new sunscreen active ingredient added to the U.S. monograph in more than 20 years.

What is bemotrizinol?

Bemotrizinol is an organic ultraviolet filter that protects across both UVA and UVB wavelengths. Under the FDA’s final order, it may be used in qualifying sunscreen products at concentrations up to 6 percent and under the other conditions established by the sunscreen monograph.

The FDA concluded that bemotrizinol is generally recognized as safe and effective when used under those conditions. That regulatory conclusion is specific: it does not mean every future formula will feel the same, suit every skin type, or perform correctly when applied too sparingly.

Permission does not mean every store has it today

The ingredient became permitted on August 9, but manufacturers determine when compliant products reach retail shelves. The American Academy of Dermatology notes that the first U.S. products containing BEMT are expected later in 2026. Check the active-ingredient panel rather than relying on front-label marketing.

How to read a sunscreen label

A new ingredient can expand choice, but the most useful label details remain familiar:

• Broad spectrum: indicates protection across UVA and UVB radiation under the required test.
• SPF: the American Academy of Dermatology recommends SPF 30 or higher for everyday exposed skin.
• Water resistance: labels state 40 or 80 minutes; “waterproof” is not an allowed promise.
• Active ingredients: this is where bemotrizinol or other UV filters are listed.
• Directions and warnings: these matter as much as the ingredient list.

The best sunscreen is still the one you use correctly

Apply sunscreen generously to exposed skin before outdoor time and reapply at least every two hours, as well as after swimming, sweating, or toweling off according to the label. Pair it with shade, protective clothing, a wide-brimmed hat, and sunglasses. In Santa Ana and across Orange County, sun protection is a year-round habit—not only a beach-day step.

If a sunscreen stings, causes a rash, or repeatedly irritates your eyes, stop using it and ask a qualified clinician for personalized guidance. A dermatologist can also help when you have a history of allergy, pigment changes, photosensitivity, skin cancer, or medications that affect sun sensitivity.

Should you replace your current sunscreen?

Not simply because a new filter is available. A current broad-spectrum sunscreen that you tolerate, apply adequately, and reapply as directed can remain a sound choice. Replace products that are expired, have changed in color or texture, or are so old that you cannot confirm when they were purchased.
