A lot of it actually comes down to consistency, but the five pillars encompass sleep, diet, exercise, or movement.

under one, and stress management.

And finally, topicals, recovery, what you can be doing topically to kind of help promote and retain a healthier barrier.

So I'll start with sleep.

There's a lot of evidence around sleep.

Of all the factors, sleep is the number one factor that we can influence to have healthy skin over time.

In fact, there was a study that was done looking at women who are good sleepers, so getting about seven to nine hours of sleep a night.

And they'd found in these patients with something called tape stripping, where they look at the top layer of their skin or the stratum corneum, that these patients had 30% better barrier recovery than patients who did not get seven to nine hours of sleep.

So that sleep is a really key aspect in better recovery, better recovery from UV-induced redness.

And they've actually found that there's fewer signs of intrinsic skin aging

compared with poor sleepers.

So it really affects not just external skin aging, but internal skin aging too.

Yeah.

So diet, think about this as your edible SPF, right?

So this is how we can manage to eat in ways that we can kind of create a healthier skin barrier and a healthier skin protection against UV damage.

So keeping those melanocytes active and healthy is very important.

We looked at a study in older adults, a pattern with high vegetables, legumes, olive oils, and

And we found that about 20% of the variation in sun-related skin damage actually patterned with eating healthier.

So patients that had more meat or butter-heavy patterns, there was actually a higher correlation with certain types of skin damage and wrinkling compared to others.

a more vegetarian and Mediterranean rich diet.
