As a child, Djibril Gueye Marvin dreamed of being a make-up artist, no easy feat in the chronically unstable Central African Republic, where he faced ridicule for doing a "girl's job".
Help came from an unusual source: the make-up tutorials that have flooded YouTube over the past decade, launching influencers across the globe and generating billions of dollars in beauty sales.
"There is no make-up school in Bangui, without YouTube tutorials I would not be where I am now," said the 23-year-old, nicknamed Djibou, who lives in the country's capital.
