WARNING: This is not for the fainthearted.
We did say - but if you managed to watch without squealing, we salute your bravery!
In the clip uploaded to the Donna Beverly Aesthetics Instagram page on Tueday (16 August), Jess sits in the salon chair, all ready for yet another plumping sesh ahead of the launch of her debut clothing collection with Prodigal Fox - but what follows is just a little nauseating...
The reality star turned fashion designer doesn't flinch at all while her cosmetic surgeon takes a pretty ha-uge needle to her already plump smackers, filling them with Juvederm - mostly hydrating and smoothing hyaluronic acid, in case you were wondering.
In fact, Jess doesn't even blink and instead pulls a cheeky pout and even does a little shimmy when the filler has been fully injected.
We can't even deal.
DB Aesthetics captioned their clip, "The stunning @miss_mae_x not even flinching as she gets a fresh plump ready for her big night on Thursday to launch her brand new clothing range!!!," and it wasn't long before the comments came flooding in.
"Nooooo! So brave!" wrote one seriously impressed follower.
But this isn't the first time gorgeous Jess - who teased her upcoming fashion drop on Instagram on Monday (14 August) - has got real honest about her use of fillers.
Earlier this year she took to Instagram (where else, eh?) to show off the results of her non-surgical nose job. Once again, she used Juvederm to fill in a little ridge - which she has always disliked - on the tip of her nose.
Since then, Ex On The Beach's Ashleigh Defty and Lacey Fuller have also talked openly about going in for facial fillers.
