"During Kylie's pregnancy, she wasn't getting her usual fillers or putting on much makeup," the source said. "Kylie really fell in love with the natural look, and wanted more of that, so she decided to stop putting filler in her lips.
“Despite the fact that Kylie is a master of branding and has made an almost billion-dollar business off her lips and cosmetics, once Stormi was born, Kylie realized she was a mother first, and that is a big reason she has been sporting the more natural look," the source added. "Kylie is a master of branding, and she plays with the concept of mother -- the more natural look -- and her Kylie Cosmetics look, full glam."
It’s unclear when or why Kylie decided to get lip fillers again after taking all of them out, but the alterations in her lip size certainly hasn’t affected her lip kit business, which is currently promoting a Halloween collection.
