The supermodel captioned a sexy snap posted to Twitter with the hashtag #fiftynomakeup

Paulina Porizkova‘s bikini body was worthy of the cover of Sports Illustrated‘s Swimsuit Issue back in 1984 (and 1985), and the supermodel is showing that nothing has changed in the past 30 years.

Porizkova — who turned 50 in April — shared a photo of herself in a blue string bikini on Twitter Tuesday that displays her enviable physique.

“Florida, time off. #brian Magallones #fiftynomakeup,” she captioned the post of herself looking #flawless.

When a commenter Tweeted that she hasn’t aged since he had photos of her posted around his dorm, Porizkova jokingly Tweeted back “only not aged when laying down.”

And while the ’90s supermodel still looks amazing, Porizkova told PEOPLE that when she was rising to fame in her 20s, she didn’t take good care of her skin.

“I was a nightmare,” she said. “I’m a product whore, so anything you gave me, I experimented with. I drank, I smoked, I’d tumble into bed with a full face of makeup on and go to work and say, ‘Look, I’m already done up.’ Sometimes it worked, sometimes it didn’t.”

Now, the star pays more attention to her routine, and never leaves the house without SPF.

“I went to a party for Estée Lauder … they had some scientists there, and I said, ‘What’s the good stuff? What’s the stuff I really need to use?’ Both of them looked at me and said, ‘Use SPF,” she said. “And I’ve used it every day since. I feel like a vampire if I go out without it.”
