This led to her feeling insecure about her looks and forcing her to overline her mouth with a lip pencil on a daily basis.
Kylie Jenner's face looks dramatically different these days, and she just revealed why.
Fans have since speculated about other procedures Kylie has undergone - including a nose job, jawline reconstruction, breast augmentation, a Brazilian butt lift and fillers around her hips - but she's never confirmed anything besides lip fillers.
Many fans flooded the comment section with messages of support, stating that the Keeping Up with the Kardashians star looks better than ever.
The 20-year-old appears to be wearing less and less make up since giving birth to baby Stormi, and now she's even reduced the size of her lips. But just when I thought 2018 couldn't get weirder, Kylie Jenner got rid of her lip filler, and I have been shook to my core.
We're loving her new look!
In a recent YouTube Q&A, Kylie joked that her daughter got her lips from father Travis Scott.
After Kylie Jenner confessed to getting lip injections in 2015, some clinics claimed that a drastic increase for lip filler procedures followed.
On Saturday, Jenner joked that her daughter Stormi has "the most ideal lips in the entire world", but she definitely didn't get them from her.
"She didn't get those from me, I think her dad has those", she quipped.
