The Loose Women panellist took to Instagram to gush about her morning with the beauty geniuses at MAC Aesthetics and shared a series of freaky facial snaps with her followers.
Katie posted a rather terrifying picture of the inside of the mask, but assured us that there's absolutely nothing to worry about, and that she would emerge looking better than ever!
The mum-of-five captioned the post: "I'm about to have a transformation #newface by @macaesthetics."
Katie was so impressed with the high-tech feature that she another two snaps with her fans and followers, even one of her wearing the mask alongside clinician Rebecca, who has tended to the faces of Sam Faiers and Charlotte Crosby, FYI.
But what the heck is this Iron Man-esque mask and why exactly do the celebs (including one of our faves, Vicky Pattison) adore it so much?
Well, believe it or not, it's actually a dry, skin rejuvenating, LED treatment that uses different lights - red, green or blue - for different purposes depending on your skin's needs.
That means it has the power to stimulate collagen, iron away wrinkles and provide you with an otherwordly glow - all without water, chemicals or mess. A total winner, right? Right.
Of course, it wasn't long before Katie's fans took to the comments section to give their thoughts on the unusual procedure.
One wrote, "Wow! I think i'd feel a bit panicky but I'd really love to try!" while another said, "I highly recommend Led Facial Treatments! Great for sun damage, reducing wrinkles and reproducing collagen."
Sounds like we're missing out! Hands up if you're thinking of booking an appointment, too?
