Could the FDA's Bemotrizinol Proposal Be a Win for Skin Cancer Prevention?
Better UV filters mean better protection - here's why the US lagged Europe and Asia and what the FDA's December 2025 bemotrizinol move could change.
On December 12, 2025, the FDA published a proposed administrative order to amend OTC sunscreen Monograph M020 to recognize bemotrizinol as a GRASE (generally recognized as safe and effective) active ingredient - the first proposed new US sunscreen filter in roughly two decades.
Dermatology commentators frame additional broad-spectrum filters as supportive of sun-protection efforts, since consistent, broad-spectrum sunscreen use is a cornerstone of reducing UV-related skin damage.
Questions we get a lot
What does GRASE mean for a sunscreen ingredient?
GRASE stands for generally recognized as safe and effective, the standard the FDA uses for over-the-counter drug ingredients. The December 12, 2025 proposed order would recognize bemotrizinol as GRASE in monograph M020. That status is what allows an active to be used in non-prescription sunscreens.
Will bemotrizinol reduce skin cancer rates?
No single ingredient can be credited with reducing cancer rates, but broad-spectrum sunscreen use is a recognized part of sun-protection strategy. The FDA's proposal would add another broad-spectrum UVA/UVB filter to the US toolkit. Consistent daily protection, not any one product, is what supports skin health over time.
Is bemotrizinol approved now?
The December 12, 2025 action is a proposed administrative order, not a final rule, so bemotrizinol is not yet on US shelves. Regulatory specialists note the agency must finalize the order before products can use the filter. The proposal recognizes it as GRASE pending that process.
