"The perfect deep brown lipstick does exist, and it was created by one of my favourite Black-owned beauty brands, AJ Crimson Beauty," said makeup artist Cooper, whose Instagram feed is not only full of photos of her fabulous clients like Andra Day, Niecy Nash, Winnie Harlow, as well as icons such as Mary J Blige and Iman, but also photos of herself rocking an array of bold lip shades (and the sharpest winged liner we've ever seen). "AJ Crimson Beauty Lipstick in Ex-Factor (£14) is a chocolate nude with cool undertones and feels as delicious on the lips as it looks," she said of one of her favourite dark lipstick shades.
