Foster, who’s also been publicly battling Lyme disease since 2012, looked fresh-faced and healthy in her fitness selfie, shared to Instagram.

“I think I am seeing the light,” the 51-year-old mom of Gigi, 20, Bella, 18, and Anwar Hadid, 16, wrote.

In the picture, the former Real Housewives of Beverly Hills star flashes the peace sign as she hits the treadmill.

“#OneDayAtATime #BeautyBehindTheMadness #3WeeksPostExplant #MyHealthJourney,” she added.

Foster identified the silicone leak as another potential factor in her health crisis in early August. In another Instagram image, she showed off the three areas along her chest where her physician found silicone that had leaked out after her implants.

“We might have hit the jackpot by finding all this silicone from a 20 year old implant rupture through ultrasound mapping as shown in this selfie. Thank you Dr.Feng for holding my hand and leading the way,” she wrote.

In the years since being diagnosed with Lyme, Foster has found her everyday functionality tested – including her ability to read and write.
