It really does work.

And they're not perfect.

They do let some ultraviolet light in, but you're going to markedly reduce your risk of skin cancer and aging and cosmetic brown spots, wrinkling and other things that people don't like.

Yeah, it's a very good question.

There has been an explosion of new medications for some of the diseases that people have heard about.

Eczema, atopic dermatitis, or atopic eczema, and psoriasis.

And the reason is over the past decade or so,

decade and a half, people have looked into the molecular chemistry of these conditions and the immunology.

And so with atopic dermatitis, for example, people have looked into the biology of this and they have been able to develop pharmaceuticals that attack the immunologic and biochemical abnormalities of these conditions.

So we'll take a condition like eczema.

Eczema has been found to have a number of abnormalities.

One of the abnormalities, the chemicals that white blood cells secrete and the way they talk to each other, they have chemicals called interleukins, interleukins.

And they know for eczema, for example, interleukin 4 and 13 are elevated, abnormally elevated.

And this causes changes in the skin function and you wind up getting eczema.

So there were people with eczema that had terrible, terrible problems with itching, redness, secondary infection.

We treated them with topical corticosteroids, sometimes systemic corticosteroids and other things.

And many of those people were able to be held in good control, but some people weren't.

Along comes a medication that attacked this abnormal elevation of interleukin 4 and 13.

It's called Dupixent.

And I'm not speaking for a pharmacy company.
