At the ripe old age of 21, reality star-turned-makeup mogul Kylie Jenner officially became the youngest self-made billionaire ever -- and the seventh youngest billionaire under the age of 30 in 2019. Facebook founder and CEO Mark Zuckerberg previously held the title as the world's youngest self-made billionaire achieving that status at the age of 23.

According to Forbes, Jenner, who started her lip kit company Kylie Cosmetics in 2015 with $250,000 of her own money that she made through modeling gigs, has grown her company into a $900 million makeup powerhouse by selling lip kits online and through Ulta stores in four years time.

And, she owns all of it. No outside investors.

Additionally, Jenner has made more than $100 million through other ventures, including appearing on her family's reality show, "Keeping Up With the Kardashians."

Jenner told the outlet that she credits "the power of social media" for her success. The youngest sister of the Kardashian-Jenner clan has more than 128 million followers on Instagram, which she uses to announce her product launches.

Other self-made billionaires on this year's list under of the age of 30 include John Collision (age 28), the co-founder of Stripe and Evan Spiegel (age 28), co-founder and CEO of Snapchat.

Anna Kasprzak, age 29, is also a newcomer this year, after inheriting $1 billion from her grandfather's Danish shoe company ECCO.
