One disgruntled user tweeted: "You washed your face for two seconds. You're using a filter. You still had makeup come off on the damn towel. LEARN HOW TO WASH YOUR FACE. How hard is this? Basic hygiene y'all."
Another skeptical person said: "Kylie Jenner is doing skincare tutorials with filters and her foundation is still on after she washed her face. Scam today. Scam tomorrow."
One fan offered a constructive critique, writing: "Love you Kylie Jenner but if you're showing people how to wash their face with your products, do it properly! Putting cleanser on your skin for two seconds and washing it off is not effective in any way. Cleanser needs to be used for at LEAST 30 secs to work effectively."
Last week, the latest teaser for KUWTK showed Kylie break her silence on the Tristan Thompson and Jordyn Woods cheating scandal for the first time.
"This is going to change your relationship forever. For you and Jordyn, it's like a divorce," Kris Jenner can be seen telling her daughter.
For the first time since the scandal broke, the billionaire business mogul admitted her best friend of over a decade "f**ked up."
The next scene shows Kylie consoling half-sister Khloe, assuring her: "Just know how much I love you."
The promo also reveals who broke the terrible news to Khloe, as Kim Kardashian's best friend Larsa Pippen is heard telling the Good American co-founder about the adulterous tryst.
"Her legs were, like, in between his legs," she said.
