Kylie Jenner, the youngest member of the Kardashian-Jenner family, launched Kylie Cosmetics on November 30, 2015, with a collection of three liquid lipsticks called Kylie Lip Kits. The $29 shades sold out immediately, with the first 30,000 units selling out within minutes of going online. The brand's success was fueled by Jenner's large Instagram following and strategic influencer partnerships, and the products have since become one of the most lucrative in the beauty industry.
