So there has been studies at small trials.

They've looked at elite athletes and looking at their cardiorespiratory fitness and looking at it with how it correlates to improvement in skin elasticity and resistance training.

I think we need more evidence on how exercise contributes to skin turnover.

We don't have good data on that yet.

But what we can say is that exercise and movement contributes to the ability of the skin to perspire and kind of excrete toxins in that way.

So I think that that plays a very important role.

We always tell our patients to do two or three times a week strength training.

And I know you've recently had Peter T on your podcast and thinking about zone two training.

Those are also important in exercise.

in connecting it back and sprinkling those short, high intensity efforts.

I think all of that collectively plays a role in keeping your skin barrier stable and strong.

Yes.

So topically, the number one product that I talk about for skin longevity is sunscreen.

And there's a lot of things that we don't understand about sunscreen that we can demystify.

So first, not all sunscreens will cover both UVA and UVB.

So really, you want to look for the label that says broad spectrum, because that's the one that's going to be comprehensive of UVA and UVB.

And reapplication of sunscreen.

This is so important.

People think, oh, I've put on sunscreen in the morning.

I'm good for the day.
