Hello and welcome to Zoe Recap, where each week we find the best bits from one of our podcast episodes to help you improve your health.

Today we're touching on skin. In 2025, global spending on skincare products is expected to approach $200 billion.

It's an astonishing figure, but not entirely surprising when you

consider the social value we place on this organ. Our skin can reflect our age, our health,

the passing of time, so chronological aging and genetics.

And I think a lot of people would expect that those have the greatest influence on how our skin ages.

So you mean, for example, if your mom's or father's skin aged well, you might think, well, that's fine, I'm going to have great skin as well.

So yes, correct.

And also that you might expect that

someone who is 70 looks older than someone who is 60. Okay, so there's also the sort of chronological age.

Then we have the second category, which are extrinsic influences on aging.

Meaning. So meaning things that impact our skin from the environment, so environmental exposures.

And actually, the most influential of these is sun exposure, and we call that photo aging.

And people will probably be amazed to hear that 80% of visible skin aging is attributable to sun exposure.

80%.
