Kylie Jenner's skincare line, Kylie Skin, is nearly sold out online despite some pretty substantial Twitter backlash. But a new video of Kylie washing her face is making people question her skincare knowledge once more.

When Jenner released the collection earlier this month, critics went after her for selling a walnut face scrub, which much of the skincare community has deemed far too harsh a physical exfoliant. To make matters worse, Kylie recommended using the scrub two to three times per week in a promotional video. Kylie, no!

On Thursday morning, the Twitter account for Kylie Skin posted a video of Jenner washing her face. She's not using the walnut scrub in the video, thank god — she's using a foaming face wash — but her cleansing method leaves a lot to be desired.

Kylie washes her face for about eight seconds. She barely puts cleanser on her forehead. And when she towels her face dry, streaks of what appears to be makeup are visible on the towel. Her face isn't even totally clean.

Now, Skincare Twitter is roasting her all over again. It might seem petty, but a skincare influencer's demonstrated expertise in her field matters, especially because these products aren't cheap. (The foaming face wash in the video costs $24.) If Jenner can't comfortably use her own product, it seems like she doesn't trust what she's selling — at least not enough to take off her own makeup with it.

We don't actually get to see what Jenner's face looks like after she's used the cleanser. The video literally has a filter on it. In contrast, think of Rihanna, whose Tutorial Tuesday videos at least give the appearance of off-the-cuff authenticity. This is ... not that.

This just proves that Kylie did no type of research and doesn’t know what she’s doing at all, not even caring she might be damaging her fans faces with horrible advice — Angelina Rose (@Ms_AngelinaRose) May 29, 2019

Rihanna would have never done this to us — indaddy (@hauntedsexts) May 29, 2019

There's always the chance that Jenner and her team knew about the foundation-streaked towel and counted on people's eagle eyes for publicity. It's a weird move, to be sure, but it's definitely a possibility.

Even if that's true, how can prospective customers trust a brand with a public face who won't publicly use her own products? Skincare, for all its status symbols and capitalist exaggerations, is an industry that can have real medical implications for people who buy in — whether it's creating tears in their faces with walnut powder or facilitating painful acne because an "expert" made them think splashing water over a dabbed-on layer of soap is the same thing as washing their face.

So, how do you wash your face correctly? Here's a nice, sort of unnerving tutorial from the American Academy of Dermatology. And if you're wearing makeup, you might want to remove it beforehand with micellar water. Kylie might have unlimited towels on hand, but you don't, so don't ruin them with unwanted streaks.

And if you do have unlimited towels? Wow. Sincere congratulations.
