Kim Kardashian at 40 opens up skincare with a new project, Skkn by Kim, which will include skincare products, hair care, nail products, perfumes, candles and more. Revenues from her brands Kkw Beauty (make-up) and Skims (shapewear and loungewear) have just brought Kim to the Forbes US billionaire list with a fortune the 40-year-old star would now hit nine zeroes. Kim was inspired by her younger sister Kylie who, after the huge success of Kylie Cosmetics, launched the Kylie Skin brand in 2019. Her mother Kris Jenner is also about to launch her own skincare line.
