The Kardashians in timelapse: watch their complete beauty transformations

An Instagram artist has created a series of time-lapse videos, showcasing just how much the Kardashian/Jenner sisters have changed since they first began their reality TV show.

The artist, who goes by the name Saint Hoax, created three separate time-lapse videos for Kylie, Kim and Khloe and the results are astonishing.

Each video suggests that the Kardashians/Jenners have dabbled in plastic surgery since beginning their hugely successful show.

18-year-old Kylie Jenner's transformation is probably the most shocking, as the young star completely changes from a raven-haired child to an adult with long green hair in her transformation clip.

The reality star has previously admitted to experimenting with lip injections, after claiming she spent years being insecure about her pout.

Media queen Kim Kardashian's video begins in 2000, when the star had baby-breath hair, noticeably curlier hair and a slightly different-shaped nose.

Cut forward 15 years and Kim is preened to perfection, with not a hair out of place or wrinkle in sight.

Khloe Kardashian is also not exempt from the wrath of the time-lapse video.

The 31-year-old starts off as a 20-something-year-old in her video, with long, dark hair, heavier make-up and thinner lips.

As the video moves on, her hair gets lighter, her cheeks more chiseled and her lips noticeably plumper.

While Kylie has owned up to her lip injections, Kim and Khloe have repeatedly denied having butt injections, nose jobs or any form of plastic surgery.
