Turns out it's not the fountain of youth that 56-year-old Salma Hayek is sipping on to look half her age - but she has opened up about the nearest thing you can get to it.
The actor and mum shared some breathtaking photos to the her Instagram grid last week.
Emerging from the ocean in a yellow two-piece swimsuit she captioned the image: "Every time I need to feel renewed I jump into the ocean", and then translated the same caption into her first language of Spanish.

Fans were kvelling over her ageless appearance with one saying: "Aka fountain of youth".
Another said: "’Looking this young in your 50s should be illegal, like what."
While a third admitted, ’’Thought this was a throwback!’’

Aside from winning the genetic lottery, in an interview with People magazine in 2015, she gave them the skinny on keeping her skin looking as plump as it did when she starred in From Dusk Till Dawn (Gen Z might need to give that one a Google), helping her avoid the Hollywood tendency to turn to Botox, explaining she's 'afraid of it'.
She said: “Right now I am doing something that I’m really loving. It is called bone broth! It’s sort of disgusting.
“You take a bunch of bones from a cow and you slow cook them for many, many hours.”
She confided she then adds a tablespoon of apple cider and drinks a cup a day of the anti-ageing elixir.

So what is it about bone broth that can give skin a boost?
Turns out Mrs Hayek Pinault has done her dermatological homework.
“It’s full of gelatin and fat and has bone marrow and I think it is very good to keep yourself young,” she explained.

“If you do the right fat, I think that is the key.
“It helps to restructure the tissues for your skin, you hair and your nails. It’s full of collagen.”
Bone broth is packed with with collagen, a structural protein found in our cartilage, bone - and our skin.
The collagen in connective tissue breaks down into nutrients your body can use, like gelatine and other health-promoting amino acids, glycine and glutamine when boiled.

Research has shown that consuming 300ml of bone broth increases plasma levels of the precursor amino acids glycine and proline, essential for collagen production.
In clinical trials, when taken as a supplement, collagen was able to improve the hydration, elasticity and appearance of wrinkles in skin.
Not convinced? It also supports healthy sleep patterns, improvs joint stiffness, pain and function in patients with osteoporosis and supports the immune function, according to PubMed.
Another one of her skincare tips might also surprise you is not washing your face - yep, you read that right.
Hayek claims the key to beautiful skin is not washing your face first thing in the morning.
During an interview with British GQ, the Magic Mike actress admitted that she skips her AM cleanse.
"My grandmother taught me to never wash my face in the morning. It's not disgusting guys,” she told fans.
Despite having access to the world’s best dermatologists and cosmetic treatments, Hayek insisted that this was the key to her youthful skin.
She explained: “What happens at night is your skin produces all the oils that your skin needs to look youthful. It regenerates. So, wash your skin really great at night but don't wash the hard work off your skin in the morning.”
Well, there you have it.
