The youngest person to ever make an appearance on the Forbes list, Kylie Jenner's fortune is more than twice as large as her second-eldest sister, Kardashian West, who Forbes listed as worth $350 million.
Thanks mostly in part to Kylie Cosmetics, Jenner has built an empire estimated to be around $900 million. Jenner owns 100 percent of her company, which Forbes values at almost $800 million.
And impressively, Kylie, who gave birth to her daughter Stormi in February, owns 100% of her company. At the time, Kris Jenner, Kylie's mother, who rakes in 10 percent of all her children's earnings, said the company had collected $420 million in retail sales over 19 months.
By comparison her half-sister, Kim Kardashian West, 37, has to scrape by on a measly net worth of $350m.
"It's incredible to be recognized for something I'm so passionate about, and I'm really grateful for that", Jenner said, according to WWD.
Forbes' Natalie Robehmed detailed how Kylie Cosmetics has found success by harnessing Jenner's enormous social-media following and slashing costs by outsourcing labour. "It could easily be an instant game-changing acquisition for any company on the hunt for a winning brand with a younger customer", senior VP or merchandising at Ulta Tara Simon said.
Granted, being born into a rich family must have given her a pretty good head start, but her hard work and business mind can't go unnoticed.
As it was previously reported, Forbes chose Ms. Kylie Jenner to grace their latest issue, and not everyone was impressed with their choice, including Dictionary.com, who explicitly stated the definition of "self-made" in their tweet.
Two years on, Kylie now sell a whole range of other cosmetics from blushers and highlighers (or "Kylighters") to eyeshadow pallettes, lip glosses and brush kits. "I was insecure about my lips, and lipstick is what helped me feel confident".
Kylie Cosmetics' overhead costs are very low, Forbes points out, making her profit margin very, very high. "It brings me so much joy to watch you continue to make your @kyliecosmetics dreams a reality!"
In a 2017 episode of the E! reality show, "Life of Kylie", the makeup mogul spoke out about becoming a CEO in her teens. "That's her thing. She loves a little bit of makeup". She credited social media with her success.
