Kylie Jenner's lip line a sell-out success

Kylie Jenner's new lipstick line has been deemed a big success after selling out instantly online.

Kim Kardashian's teenage sister launched the Kylie Matte Liquid Lipstick & Lip Liner kits on Monday (30Nov15) in her three signature shades - Candy K, Dolce K, and TrueBrown K - and fans snapped them up as soon as they went live on her website.

The high demand for the make-up products caused the dedicated site to crash, prompting droves of followers to complain to Kylie via Twitter.

"Nobody be upset!," she wrote in response. "There's so many people trying to buy at once so there are some tech issues. Everybody stand by and keep trying! We r (sic) working on it."

However, as soon as the traffic problem was fixed, upset customers discovered the lip colors had all gone.

"They are now officially sold out!," she exclaimed, before promising, "But more will be released before Christmas!"

The 18-year-old Keeping Up With the Kardashians star's successful launch emerges six months after Kylie admitted to undergoing a lip filler procedure to plump up her pout.

She had previously insisted her luscious look was down to clever make-up, but in an episode of Keeping Up with the Kardashians in May (15), she confessed to having had a little cosmetic help.

"I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do," she explained.

"I'm just not ready to talk to reporters about my lips yet because everyone always picks us (her family) apart," she continued as she revealed why she had initially dodged questions about her look. "I want to admit to the lips, but people are so quick to judge me on everything, so I might have tiptoed around the truth, but I didn't lie."

Kylie isn't the only member of the family to become a make-up maven - Kim and her sisters, Khloe and Kourtney, have their own Kardashian Beauty cosmetics collection, too.
