Can't stop watching: The incredible transformation of the Kardashians' faces.

Maybe she’s born with it… Maybe it’s a bit more than “contouring”.

It’s no secret that the Kardashians are fond of a little “cosmetic touch-up” every now and then.

But apart from admissions of breast implants for eldest sister Kourtney and lip fillers for youngest sister Kylie, the famous family have been coy about other changes to the rest of their faces.

A new series of videos going viral, though, suggest that the Kardashians have had a little extra help from cosmetic surgery on the side.

The videos were made by self-professed “politically incorrect artist/sociopolitical activist” Saint Hoax, who photoshopped a doctor’s needle onto the side of each of the women’s faces.

Saint Hoax first released the changing image of youngest Kylie:

Next, she released a video of Kim’s changing face:

Then Khloe’s:

And finally, all the Kardashians’ faces:

The reception on Saint Hoax’s Instagram page has been mostly negative toward the Kardashian sisters, with one user commenting, “It’s sad” and another writing, “I told you all that mess wasn’t her naturally”.

Although his latest artwork has created a stir, but this isn’t the first time the artist has been in the media for his work. Whether you love them or loathe them, each of Saint Hoax’s pieces triggers a reaction and a conversation about everyday issues that are affecting so many of us.

Even if it takes a Kardashian to do so, that can only be a good thing.
