Sarah Jessica Parker is obsessed with this $30 moisturizer

We couldn't help but wonder, how does Carrie Bradshaw still look this good!

Though she's known as being the best-dressed celebrity on-and-off the red carpet, Sarah Jessica Parker's remarkable beauty is just as iconic as her clothes. SJP in 2019 is the same SJP we first saw in season one of "Sex and the City" back in 1998. Carrie Bradshaw truly just gets better with age.

In a recent interview with "TODAY," SJP revealed her 'absolute favorite' product without hesitation. “I only have one...It’s the only moisturizer I’ve used forever. It’s just La Roche-Posay fluid. That’s it. It’s amazing. It’s very thin, so you can use it to touch yourself up. It’s great.”

The $29.99 daily moisturizer is infused with spring water to hydrate, soothe and protect highly sensitive skin.
