Whereas with BEMT, you can do so a little bit more efficiently without taking up so much of the sunscreen's real estate.

Now, the only other UV filter that does absorb broad spectrum is abobenzone allowed in the United States.

But the thing about abobenzone is that it does require other UV filters to stabilize it.

So this is really the most efficient UV filter as far as that.

And what's the difference between UVA and UVB light?

So UVB light, particularly, I think we associate more with sunburn, whereas UVA light, we associate more with photoaging, skin darkening, more of those cosmetic concerns that you see.

Yes.

To pass any UV filter in the United States, it requires a lot of toxicological evidence and it requires evidence of understanding how

A filter could interact with human biology.

What's great about BEMT is that it's actually a lot larger of a molecule than other UV filters that we've seen.

And so it's well beyond a limit that one would be concerned for, you know, extreme biological damage.

absorption profiles or exposure that could be harmful to the human skin or human body.

So that's also a really great advantage because the toxicity risk profile is significantly lower than one would expect.

So, you know, that can be kind of a deterrent for a lot of people for wearing sunscreens.

It all comes down to light scattering.

Any color that we can see is a consequence of something reflecting visible light.

And so what's really great about zinc oxide and titanium dioxide is that they

can absorb UV, but they also scatter light in such a way that we can see the color white.

And that also can be caused by aggregation and agglomerates of these zinc oxide and titanium dioxide minerals, particles, in such a way that larger aggregates scatter more visible light.

Those are inherently pigments as well.
