Supermodels aren’t like the rest of us. The average person doesn’t get paid to pose in a bikini or pretend that they are a 1920s flapper for some shoot during their average work day. Furthermore, models manage to make even the craziest designer pieces look almost wearable. You couldn’t pull off that garbage bag dress. Supermodels also seem to be immune to aging. Former Sports Illustrated cover girl Paulina Porizkova recently uploaded a photo to Twitter of herself in a bikini and it looks like she has barely aged a day since her first magazine cover.

The 50-year-old isn’t the only supermodel who simply doesn’t age. Most of the big models from the 1980s and 1990s look as youthful now as they did over a decade ago. You could say they’ve had a little help with good cosmetics, having access to industry experts and maybe a few procedures, but it could just be some gene that slows down the aging process.

Check out 8 other supermodels who do not seem to age:

Christie Brinkley may be 60, but she can still pass for her teenage daughter’s sister. Can you believe that this People magazine cover was shot 34 years after the Sports Illustrated one? For real.

2. Cindy CrawfordCindy Crawford

If 49-year-old Cindy Crawford has a moment, can she please let us know exactly what her skincare regimen is because it is definitely working. If we could also find out the secret to her voluminous hair, that would also be appreciated.

3. Naomi CampbellNaomi Campbell

If Naomi Capmbell played with the app that guesses your age, it would probably say she was in her mid-twenties in all of her photos. Not much has changed about the 45-year-old when you compare her recent magazine covers with ones from the late 90s.

4. Claudia SchifferClaudia Schiffer

It doesn’t matter how many different models are on the list, you are still surprised with seeing each age-defying one. If you ignored the crazy type and the makeup, could you really figure out what was 44-year-old Claudia Schiffer‘s most recent magazine cover?

How long would you have guessed it had been since Heidi Klum‘s Sports Illustrated cover? Three years max? No one would have suspected that there was over 15 years separating the 41-year-old’s two swimsuit covers.

6. Tyra BanksTyra Banks

41-year-old Tyra Banks may have recently chopped her hair into a pixie cut but that is about the only thing that has changed. Put all of the seasons of America’s Next Top Model together and good luck telling season 1 from season 503.

7. Helena ChristensenHelena Christensen

Helena Christensen is one of the many models on the list who is still posing in editorials and campaigns. Not much has changed in 14 years to the 46-year-old when you compare these covers, even her facial expression is the same.

8. Elle MacphersonElle Macpherson

When you google “Elle Macpherson” the first few things that come up are “age, diet and workout.” Clearly everyone is trying to find out how the 51-year-old seems to have made time stand still when it comes to her look.
