The 57-year-old Dusk Till Dawn star soaked up the sun with her husband François-Henri Pinault as they enjoyed a vacation on a tropical island.
Salma shared a few photos from a private yacht on Monday via Instagram.
The star donned a tiny blue patterned bikini that revealed her toned figure that has not changed since she was in her 20s.
Her ample cleavage was pushed up with the tiny bikini top and she left her dark locks unstyled.
In the photos, Salma stood on a ladder that hung off the side of her boat.
Behind her, Salma's stepson Augie could be seen swimming in the bright-blue ocean.
Her family were throwing water at her as she attempted to get back on the boat after enjoying a swim.
Salma smiled and covered her face in the photos.
"When your family won’t let you take a bikini pic in peace," she captioned the post with laughing face emojis.
Salma and François share one daughter, Valentina Paloma Pinault, 17, while François has three other children from a previous marriage.
Mathilde and her brothers, François and Augustin were all born to François and his ex-wife, Dorothée Lepère.
Fans flooded the comment section with admiration for the star and her young looks.
"You look great," wrote a follower.
"Perfect body forever, perfect dream," added another.
"Perfection," simply said a third.
Several fans were lost for words and left heart and fire emojis to express their amazement, while some claimed she still "look[s] 22."
FEELING BLUE?
This was not the first time Salma stunned in a bikini, with the star showing off her youthful figure last week.
The Frida star posted a swimsuit photo on Wednesday, accompanied by some inspirational quotes, on social media.
The selfie showed Salma wearing a plunging blue one-piece swimsuit while sitting at the nose of a boat.
The ocean in the background, swimwear hugging her curves, and the sapphire-tinted Oakley sunglasses on her face all matched the Magic Mike star's blue theme.
"It’s okay to be blue," she captioned the photo.
Salma finished with a blue heart emoji and added the hashtag, "azul," the Spanish translation for blue.
She also shared text posts with passages about the color blue.
The first read, "Blue is the colour of the clear sky and the deep sea. It is located between violet and green on the optical spectrum."
It continued, "Surveys in the U.S. and Europe show that blue is the colour most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and sometimes with sadness."
