"What her half-sister Kim Kardashian West did for booty, Jenner has done for full lips," Forbes writes, describing her famous pout.
Earlier this week Ms Jenner, a mother of one daughter named Stormi, announced she would stop receiving lip injections, known as dermal fillers.
She admitted during an episode of Keeping Up With The Kardashians in 2015 that her natural lips had been "an insecurity" that she wanted to change with temporary lip fillers.She later launched her brand Kylie Cosmetics, which included a line of lip products designed to help customers make their lips look bigger through over-lining and filling.
Unlike those of traditional cosmetic brands, her products are almost exclusively sold online.
Her cosmetics have proven exceptionally popular with fans, selling out almost instantly at every website re-stock and leading to server crashes.
Ms Jenner's company, which she wholly owns, is worth $800m, according to Forbes.
She is number 27 on Forbes' list of richest self-made women in America, leap-frogging Barbra Streisand ($400m), Beyonce Knowles ($335m) and Taylor Swift ($320m). —BBC Online
