Make-up artist AJ Crimson has died aged 27. His cause of death has not been revealed.
As the chief executive of AJ Crimson Beauty, Crimson was known for his inclusive work in the cosmetics industry and expertise in black beauty.
"AJ Crimson was a make-up industry leader that set a standard of beauty that was elevated, beautiful and accessible to people of all colour," Crimson's family told ET.
"We as a family are heartbroken and devastated by his passing, but thankful for the lessons that he laid on each of us with his truth, directness and leadership.
"We thank you all for your kind words, tweets and posts, as AJ was an inspiration to us as much as he was a bright light to the rest of the world. There are no words that can sum up his whole. Until we meet again!"
He worked with a number of celebrities, including Lauren London, Missy Elliott, Regina King, Angela Bassett, Hilary Duff, Christina Milian and Fergie.
Crimson started his business in 2012, beginning with lipsticks and glosses before expanding to foundations, finishing powders, artist kits and make-up brushes. His last Instagram post was on March 25, when he was promoting his new vegan fibre make-up brush collection.
Sir John, Beyonce's long-time make-up artist, posted a tribute to Crimson on Instagram, saying he was "in disbelief."
"This cuts deep," he wrote. "Holding space for black women was at your core."
