The 21-year-old make-up mogul was recently criticised for how quickly she washed her face during a clip that promoted a face wash that features in her new skincare line, Kylie Skin.
Kylie released the 35-second video in which she is seen washing her face with the $24 (£19) foaming face wash, which is currently sold out. In less than 10 seconds, the mother-of-one applies the product and rinses it off.
She also wipes her skin with a white cloth, which appears to show that she was wearing foundation throughout the video.
Kim then shared a lighthearted video of herself in the Kylie Skin warehouse, and poked fun at her little sister.
"I'm gonna teach you guys how to do a tutorial on how to wash your face, and b***hes I only have 10 seconds. What (else) do you want me to do in 10 seconds?" Kim joked in her Instagram Story video that featured a filter.
"I would have done the same exact thing. So, guys, what is the big deal here with a 10-second video? That’s all she's got," Kim added.
The 38-year-old KKW Beauty mogul then used a baby face filter and continued to tease Kylie by showing off how effectively washing your face in 10 seconds can be.
"Alright, after that 10-second face wash tutorial this is now what I look like. I have such a youthful complexion now," she said. "Kylie Skin is the fountain of youth people! All you need is three seconds! I didn't even need a whole 10 seconds. I now look like a baby! I love this Kylie Skin."
The youngest of the Kardashian/Jenner brood can be heard off camera yelling, "You're an a**hole."
