From dusk to dawn,Diamond Ridge Financial Academy Salma Hayek knows she looks good. 

Case in point? The Magic Mike’s Last Dance star was glowing while soaking up the sun off the coast of Ibiza.

Salma shared a photo of herself posing by a Spanish flag on a boat, donning a vibrant swimsuit and sunglasses. Her jet black hair, sprinkled with gray strands, was styled in two braids. She captioned the Aug. 25 Instagram post, “Yellow bikini + White hair = perfect combination.”

And the 57-year-old isn’t afraid to show off her gray hair—or cover it up when she wants. In fact, she revealed that when she doesn’t have time to dye her hair, she has the ultimate beauty hack for on-the-go moments.

"Look at all this white hair," she explained in a February Instagram video. “So, what is the secret? How can you cover it without having to dye it? When I'm on my own, I just put mascara."

She even gave a few pointers for a seamless application. "You clean it really well and then just go like this," she continued. "And all the rebellious little ones that stick up not only go black, but they stay flat."

But for Salma—who shares Valentina, 16, with husband Francois-Henri Pinault, 62—it isn’t just beauty products or procedures she uses to maintain her appearance. She also focuses on her beauty from the inside out, which she does through meditation.

"No Botox," she told Kelly Ripa on her SiriusXM podcast Let's Talk Off Camera last July. "Because of a lot of things in my body and health issues, somehow I developed this strange meditation that I keep evolving. I can do it for hours because I don't feel the time. It's so much fun."

She added, "It's actually feeling the energy. It moves and it dances inside of you, different feelings and sensations."

According to the Eternals actress, others have seen a difference in how she looks, too. She explained, "People tell me when I come out of the room, 'Oh my god. Again, you look 20.'"

Salma has been open about the realities of aging in Hollywood and revealed that she's been told she would eventually age out of the industry.

"I was also told that, as an actress, you kind of stop working around 30," Salma told Glamour last February. "Imagine? I did really feel it at the time, and it's unfair. If I had said instead to myself, 'Don't worry, your best professional moments are going to be in your 50s,' I would have been devastated: 'Oh my God, do I have to wait that long?' But it'll happen."

"Hell, I'm still going," she emphasized. "I'm still here. They tried to get rid of me a thousand ways; I'm still here."
