Those who follow Instagram makeup channels know perfectly that the tons of highlighters, eyeshadows and contouring that the so-called "beauty gurus" love to cover themselves with hide nothing but a universe full of greed, resentment and envy for others. What fans don't see behind a simple video tutorial on how to apply eyeliner is a fierce competition between those who win the best partnership. In fact, since YouTube was born, the cosmetics industry has had to submit to the whims and feuds of an Olympus of very powerful influencers and the underworld that emulates them. They are the ones who dictate the laws of the market, who decide the trends of the moment, who destroy or inflate the reputation of a brand. Only the products mentioned in their videos can have any hope of success in an increasingly demanding, fast and competitive market, so much so that some even talk about fast beauty. And just as is already the case with fast fashion, this sector does not stand out for ethical integrity.
