"I don't want to do it with anyone else, '" Jenner told Forbes, saying she used almost a quarter million dollars of her own money from modeling to make the first 15,000 lip kits.
Kylie Cosmetics has already generated an estimated $230 million in net profit and Forbes predicts that sometime later this year, Jenner will likely become the youngest self-made billionaire in the world - a title that Bill Gates and Mark Zuckerberg once held.
The Facebook founder, who is now estimated to be worth more than $70 billion, went from millionaire to billionaire at age 23.
Dictionary.com was quick to point out that, "self-made means having succeeded in life unaided", and then posted this example, apparently in jest: "Used in a sentence: Forbes says that Kylie Jenner is a self-made woman". Her plumped up lips undoubtedly helped her sell the lip kits that do NOT include the fillers responsible for her flawless pout. Jenner owns 100% of it.
Jenner's company, which she wholly owns, is worth $800m, according to Forbes.
On Wednesday, Forbes released its August 2018 "America's Women Billionaires" issue with Jenner on the cover.
"I have such easy access to my fans and my customers", she said.
Even if you've been living under a rock, you will know Kylie Jenner.
"Thank you @Forbes for this article and the recognition".
However, followers were divided over the 20-year-old's decision to pierce her ears at such a young age.
However, the "haters" won't hinder the young businesswoman and, in fact, only add "fuel" to her work ethic. Kris Jenner manages her daughters' finances and public relations for a 10 percent cut - meaning that a year ago, Kylie paid her mom $17 million.
Jenner, who is now not old enough even to legally drink alcohol in the USA, will turn 21 in August before her Forbes cover edition hits newsstands. "Kim is not giving her credit for coming up with these things, and Kylie is just sick of it".
