Lucky for us, Kenny has spilled the tea on her most prized beauty trick via her app.
In the post, the model's makeup artist Mary Phillips explains how rubbing leftover serum from your face mask onto your body can extend the ~goodness~ from your face to your whole body.
As we all know, your face actually stops at your chest, NOT your chiny chin chin, so you should be using the same amount of product on your face, neck and chest for maximum effect.
Just think of the time and money you'll save by sharing the love between your face and your bod!!
Kendall may make some silly AF decisions (i.e. that Pepsi ad and those t-shirts), but she certainly knows a thing or two about beauty.
Pure genius, Kenny.
