Jenner, who lands the magazine’s cover feature, is the sole owner of Kylie Cosmetics, which Forbes estimates at nearly $800 million dollars. The company’s signature (and first) product—its Lip Kits—have sold more than $630 million since their February 2016 debut, with an estimated $330 million of sales in 2017.
When paired with her earnings from endorsements, television and after-tax dividends from Kylie Cosmetics, Jenner is “conservatively worth $900 million, which along with her age makes her the youngest person on the fourth annual ranking of America's Richest Self-Made Women,” states the magazine. (Jenner’s sister Kim Kardashian West, by comparison, has an estimated worth of $350.)
The publication adds: “Another year of growth will make her the youngest self-made billionaire ever, male or female, trumping Mark Zuckerberg, who became a billionaire at age 23. (Snapchat's Evan Spiegel also became a billionaire in his early 20s, though it's less clear when he passed that threshold.)”
The brand’s success is driven by Jenner’s social media presence, including 110 million followers on Instagram, 25.6 million on Twitter, and 16.4 million followers on the company’s platforms. It is manufactured by private-label cosmetics company Spatz Laboratories, a subsidiary of Seed Beauty (which handles packaging and shipping fulfillment, among other aspects of the business).
Other cosmetics industry women featured in the issue include Anastasia Soare of Anastasia Beverley Hills, with an estimated worth of $1 billion; and mega influencer Huda Kattan (26 million Instagram followers), whose Huda Beauty sold a minority stake to TSG Consumer Partners in December 2017 and recently received a $1 billion valuation.
