In another post, a video of Liam undergoing the procedure was shared, where it explained he had anti wrinkle injections and filler done to his face.
"Reality TV star @lcoop_13 visited Dr Phoebe for a facial rejuvenation this week!" the caption read.
"Using anti wrinkle injections to remove frown lines and filler to define his jawline giving him a fresher look."

Liam reshared the video to his own Instagram, and wrote: "Two weeks ago I went and visited @conceptcosmetic to see the very talent @beautybydrphoebe for a facial rejuvenation!
Dr Phoebe used anti wrinkle to remove my frown lines and injected filler to define my jaw line," he said.
"I have always struggled with my jawline and I couldn’t be happier with the end results."
It comes after Liam revealed he'd become 'self conscious' since leaving the show, and after a video of his co-star Jason Engler taking aim at his physical appearance was leaked.
"Before that video, to me, my body was normal. I was healthy and I was happy in my own skin, however, that video destroyed me," he wrote.
"It left me hating my body. I hated when people would touch me, hug me, even look at me. It affected my mental health, I became self conscious and I did not know the Liam I was looking at.
That video sucked the life out of me. To this day, I am still trying to deal with all the above and how this video has affected me," he said.
