Well... one I recommended recently as she was one of the only people to showcase a product(s) in question within a title of a thread (in a different designer forum) and seemed trustworthy. Mainly, I think that was because she a) was genuinely interested in the products for herself and b) she spent her own money on them.
I noticed after my posting she immediately get a huge PR gift from the brand in question and now has sponsorship from another brand I mentioned her in an article somewhere else (again, for her honest opinions). Almost at once I could see slight change her behaviour, the annoying regularity of ads before, during and after each vid...and so now I'm keeping my big mouth shut about my go-to beauty reviewers.
I don't begrudge the PR products or sponsorships but let's not kid ourselves that YT, TkTk or Insta influencers basically don't end-up being advertorial once they reach a certain level.
This is my long-winded way of me saying since no one's paying me, most influencers can kick-start their own careers without my help. It also shows the power of tPF should never be underestimated!
Now having said that I will make an exception because do like John Mclean because he's wonderful at makeup, has so much personality with zero vulgarity. He has no time for anything he doesn't like including trends:
I also have always enjoyed Fumi Desalu Vold because she buys Hermes and Zara with equal pleasure and is so much fun without ever being patronising or vulgar - but she was a model and she is a commercial brand so I have no illusions. Some of her quotes are priceless though " I love colour because of what colour can do for me!" She's so old' school and the lady I'm not, I really just watch her for watching her sake, Vogue is not nearly as entertaining (at least not any more).
