Back in 2015, Kendall revealed her acne made her feel like an "outcast" during her teenage years. Writing on her app, she explained: "It completely ruined my self-esteem. I wouldn't even look at people when I talked to them. I felt like such an outcast; when I spoke, it was with my hand covering my face. Sure, I had crushes in high school, but I wouldn't even think about looking at guys."
