Kylie Jenner Puts Skincare Game on Skates ... w/ Roller Rink Beauty Event

Kylie Jenner is doing laps around the competition in the beauty game, which she illustrated perfectly during the launch for her new skincare brand ... basically, a roller skater's dream.

Kris Jenner's youngest hosted her mom, dad, sisters and a bunch of friends Tuesday night at the Goya Studios Sound Stage in Hollywood to celebrate the launch of Kylie Skin -- her latest beauty line. It was essentially a roller rink bash for adults ... and looked super fun.

Kylie caught a lot of the action from inside, and it's clear she had a theme -- pink and white hotties on four wheels going around and around. She also had some good grub on hand too -- everything from pizza to sushi ... plus, samples of her actual products.

While the event was truly a family affair -- Kim, Khloe, Kourtney, Caitlyn and even her brother, Brandon, made appearances -- however, no sign of Travis here.

It appears he's on the road at the moment, but he was there in spirit ... his music was blasting in the background.
