She read French and Russian literature at Oxford so woman is no slouch in the brain box department but we're about the way she looks. At least today.
How does she do it? Well, clearly she got lucky in the gene pool but Kate also works at keeping herself looking so damn fine. And here is what she is said to do.
For that peaches and cream complexion it's none other than Cetaphil Soap. Kate likes it in bar form.
"I use Cetaphil soap, no kidding," Kate told US Today.
Kate is also clever when it comes to protecting that lovely skin of hers. She never steps outside without a generous coating of sunscreen ensuring she stays dewy fresh as long as is possible.
“Sunscreen. It was fashionable to be tan when I was growing up. And yet, I was lucky. I would get freckles in the shape of a military mustache. So I was obsessed with sunscreen. I didn’t get sun damage. Now I use La Roche-Posay. It doesn’t make me break out,” she said.
Kate also exfoliates regularly ensuring she buffs off any dead skin cells sitting on the surface of her skin. Regular exfoliation can make a huge difference to skin, says beauty expert and founder of the Paula's Choice skincare line Paula Begoun.
"Helping skin shed the excess buildup of accumulated skin cells, caused mostly from sun damage or having oily/combination or breakout-prone skin, can make all the difference in the world."
Aside from that Kate says she enjoys skin oils. And why not? They've been shown to soothe and soften skin making it look and feel richly hydrated.
Some can even ease the appearance of stretch marks and age spots plus even skin tone. We like Trilogy Certified Organic Rosehip Oil (20ml), $25.95.
Of course, dating someone 20 years your junior might also add a little glow. But if there's no Pete Davidson in your life currently, these skincare products should do the trick anyway. And for a little inspiration, scroll down for one more pic of the incredibly ageless Kate.
