Later, she added another photograph of herself from 2010, when she was just 19, where her natural lip shape can be seen.
However, from Jess's caption she sounds unhappy with her pre-surgery look.
"2010 Jess. I never smiled as I had horrible teeth and was very self conscious of that," Jess captioned the throwback snap.
"I feel it shows in this photo and I actually get a little sad looking at it."
While Jess may prefer her new surgically enhanced appearance, fans have begun commenting that she's gone too far with her lip augmentations.
"You've overdone your lips 😨" one fan commented on a recent Instagram pic.
"Jessika i love you but please leave your lips alone...im not hating but i just think your [sic] gorgeous the way you are right now ❤" said another worried fan.
The pics come just days after Jess showed off the bruises from her breast lift on her Instagram.
Speaking to fans, Jess said she'd chosen the fat transfer surgery, as she didn't want a traditional boob job involving silicone implants.
"I definitely feel like it was worth the money," she said in a video.
"I didn't want to have silicone boobs, not that there is anything wrong with that, I just didn't want it for myself.
"I had the smallest little bit of unwanted fat on the side of my thighs that I wanted to remove so two birds one stone," she shared, before posting the graphic before and after photos of her bruised breasts.
