Unadulterated 'honesty' can actually be quite hard to find on Instagram. There are a lot of people out there who purport to be honest - with lengthy captions about body positivity and real, unposed gym selfies. But quite often, these are just as contrived as the photoshopped guff they rail against.
Celebrity accounts, though, are some of the most polished, poised and photoshopped available, complete with art direction and three rounds of face tuning.
Occasionally in celebland though, there's that brilliant diamond in the rough, who pulls back the curtain just a tad to reveal something of their un-perfected self to the masses.
Drew Barrymore is something of a Queen when it comes to beauty.
The 42 year-old actress and entrepreneur (she owns a cosmetics company called Flower Beauty) recently took us through all her beauty tips and tricks for a #beautyjunkieweek.
And though she is clearly something of a make-up hoarder, with some fabulous tricks for the working woman, she is far from perfection obsessed.
In fact, her whole beauty ethos revolves around simple, affordable, at-home methods to make you feel good.
And, despite owning what looks like a zillion different lipsticks, she doesn't take it too seriously, putting first your life and how you feel over flawless eye-creases and the perfect cupid's bow.
Showing that she most certainly practises what she preaches, Drew posted this super-relatable snap of her untended eyebrows and some stray greys to prove she's as prone to missing the salon as the rest of us.
Personally we love a full brow, and grey hairs are so in right now (why not go for the whole head?).
Drew commented on the post explaining she needed to get to the salon ASAP ready to film the second season of her hit Netflix show, the Santa Clarita Diet, saying:
'OH MY GOD How did I let it get this bad. Base and brows needed. Must become her. #santaclaritadiet here we go again. Season two.'
Whether you genuinely forgot Drew, or you just don't give a f****, we're totally here for your real Instagram posts.
