If you use it as intended, which is what would make it effective, there's a lot more of it that's ending up in our bloodstream than we realized.

And the concern is that we don't know enough about its safety.

So what the FDA has asked the manufacturers of these chemicals and really these products to do is to do studies where the sunscreen would be used as intended.

and then see how much of these chemicals end up in the bloodstream.

Because the FDA has standards for how much of these chemicals should be in our blood, and currently they can't meet that standard of both safe and effective.

You know, I spent a lot of my career criticizing the way that regulatory agencies make decisions.

I think we should actually give them credit when they can acknowledge that what they thought before, there isn't enough evidence to support it.

In this case, I think that really what they're doing is signaling that there isn't enough evidence to say that they're dangerous.

But that's not the standard that we should have for products that we're putting all over our body, for products we're putting on the bodies of children.

We want to know that they're safe, but we also want to know that they're doing the job because the job of sunscreens is really critical.
