Macpherson posted a shocking before-and-after image on social media to show off the results of her latest treatment.
"Love @sheilamsperez lymph day," she wrote, referencing celebrity lymphatic drainage expert, Sheila Perez.
The mother-of-two added more details about Perez in her Instagram Stories.
"Special method developed by Sheila for lymphatic drainage and sculpting - they call her the torturer!" Macpherson wrote. "But we still keep coming back because it works!"
Back in June 2018, Macpherson insisted on U.K. talk show “This Morning” she hasn’t gone under the knife to stay looking forever young.
“I haven’t done any plastic surgery, not that I have any judgment — it just hasn’t been my choice,” said Macpherson. “I like a natural-looking face.”
Macpherson, who skyrocketed to fame in the ‘80s, declared she’s proud of how her body has changed over the years, especially after becoming a mother to two sons.
“I try to do some exercise every day, but thank goodness I don’t have the same body as in my 20s,” she said. “This body has birthed two incredible boys and lived through amazing stages of fashion and fitness. There have been many changes and I’m grateful to be able to evolve over time. I’m open to change and evolving. These are tangible assets to my life.”
