One fan responded to the negativity, tweeting: "Ok but @Kendall Jenner showing up and strutting her acne while looking like a gorgeous star is what every girl needs to understand."
Kendall re-tweeted this with the simple and brilliant caption: "never let that shit stop you! 😎 ✨."
It's not the first time Kendall has addressed her acne, previously writing on her blog:
"I had such bad acne when I was younger. 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. Even after things started to clear up, it took a solid amount of time to be okay with my skin and gain back my confidence. I realized that it's a part of life for some people and it doesn't define who you are."
