The 19-year-old 'Keeping Up With the Kardashians' star has admitted she "dreads" going to the beauty salon to have a new sweep of eyelashes fitted in every two weeks because she struggles to keep her eyes closed without falling asleep.

Speaking about the beauty treatment she fears the most, she told PEOPLE: "I get my lash extensions filled every two weeks. I actually dread it - keeping your eyes closed and being awake for that long gives me anxiety."

Although the television personality works herself up into a frenzy prior to her pampering session, she will continue with the procedure because she "loves" the way she looks.

She explained: "But I love the way it looks, so it's so worth it. Now I do the same length as my own lashes, just to fill them out. It looks way more natural."

And the beauty mogul - who launched her beauty empire Kylie Cosmetics earlier this year and has a nail collection with Sinful Colours - has revealed she gets a manicure and a new set of "pretty nails" every week, which is a habit her 60-year-old momager, Kris Jenner, "drilled" into her at a young age.

She said: "My mom always drilled it in my head to have nice, pretty nails. I never cared when I was younger, but now I get my nails done every week. I've sat literally for four to five hours doing them. I used to spend so much time doing the craziest artwork."

However, Kylie - who is currently dating 'Rack City' hitmaker Tyga - has revealed she treats herself to a spray tan, but will only get it done in the evening or the early hours of the morning.

She explained: "I get spray tans pretty late [at night]. Sometimes I'll decide last minute. My spray tan guy, Jimmy Coco, is always busy, so he tells me he can come at 12:45 a.m. And I'm like, 'I'm down!'"
