The Kardashian/Jenner clan is pretty good at keeping fans in the loop when it comes to top beauty tips and secrets. And if you’ve been keeping up with the reality stars for as long as we have, you know sisters Kim and Kourtney are known to hop on some pretty strange and under-the-radar bandwagons. In fact, there’s one formula they use that still has us scratching our heads. 

Earlier this year, Kourtney Kardashian, 40, shared a photo of herself and Kim Kardashian, 39, using Hanacure’s The All-In-One Facial, which is often dubbed “the world’s most powerful skincare product.”

“Kim convinced me to use this face mask and I feel stunning,” Kourtney explained on Instagram.

The popular dermatologist-tested mask, powered by a CO2 Octolift compound and essential botanicals, temporarily tightens the skin and apparently makes people look like they’ve aged. It’s known to increase collagen and reveal a smoother and brighter complexion — after you rinse, that is. Also formulated with Acetyl Hexapeptide-8, a non-invasive alternative to Botox, it magically reduces the appearance of wrinkles after just one use.

“It was incredibly tight as it dried. I looked in the mirror and saw a monster staring back at me! Lol. My face felt amazing afterwards,” says one reviewer, who gave it a five-star rating. 

“Incredible product. Used just once and INSTANT difference. Bought a whole set right after. Can’t wait to do it again! Never been so obsessed with a product in my life,” adds another reviewer.

Designed for one application, each order includes a lifting serum, a gelling pack and a brush for a steep price of $29. But as pricey as this multi-action treatment mask can be, 93 per cent of users would recommend it to friends and family, while 90 per cent of users agree that it improves the skin’s overall appearance.  

There’s also the option to purchase a set of four treatment masks.
