Kendall Jenner "felt like such an outcast" when she was younger.
The 19-year-old model struggled with low self-esteem as a result of having bad acne for many years before carving out a career in the fashion industry.
In a new post on her website, the 'Keeping Up with the Kardashians' beauty shared: "I had such bad acne when I was younger; I remember it SO well!
"Where it really impacted me was how self-conscious I became about it. 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."
Kendall credits her older sisters for giving her beauty tips to make her feel better.
She explained: "They would help me work on my feelings about it and how I would move past that stage of my life."
The brunette beauty eventually sought help from her "incredible dermatologist," who has helped her be "acne-free for about three years now."
But Kendall still feels "a little bit self-conscious" every now and then.
She added: "Slowly, I'm working towards not caring and I'm just in so much of a better place about it all now that I'm older. I realised that it's a part of life for some people and it doesn't define who you are."
