Kylie Jenner got plenty of family support when she held her skin product launch at a skating rink on Tuesday. The 21-year-old cosmetics icon was joined by her half-sisters Kourtney, Kim and Khoe Kardashian, as well as her parents Kris and Caitlyn Jenner as she made a sensational display in a sexy pink mini with racy cut-outs. Various family members fired up their Insta Stories over the course of the evening to let their fans in on the luxurious festivities while Kylie was leading the pack in her sexy look. Kylie slipped into a powder pink leather strapless mini-dress with peekaboo sides, flashing her taut midriff for the cameras while also giving a hint of her eye-popping cleavage in the ensemble. She wore her raven tresses in tumbling lengths with a centre parting while ensuring her make-up, which has earned her billionaire status, was flawlessly styled to best show off her products. Her skin was certainly glowing as she appeared at the bash, no doubt thanks to her new line which has set the Internet alight since she revealed the walnut scrub included in her skincare. She said of the scrub: 'It's really gentle - gentle enough to use every day. I'd recommend two or three times a week, that's how much I use it. Some walnut face scrubs are kinda harsh on the skin. This isn't too abrasive...it really leaves my skin feeling super baby soft, just makes you look glowy, takes away dead skin cells' Sizzling: The 21-year-old slipped into a powder pink leather strapless mini-dress with peekaboo sides, flashing her taut midriff for the cameras Supported: As one of the most famous women in the world, Kylie was of course flanked by security guards Sizzling: She was smouldering in her saucy look which made the most of her lithe legs and sexy figure Amazing: Kylie got plenty of family support when she held her skin product launch Quintet: The cosmetics icon was joined by her half-sisters Kourtney, Kim and Khoe Kardashian, as well as her parents Kris and Caitlyn Jenner Nude ambition: Also in attendance was supportive sister Khloe, who flaunted her curves in a very tight nude PVC strapless catsuit at the launch Swanky: Meanwhile, Kim was in a floor-length pink turtleneck gown with full sleeves, showing off her chiseled figure in the skintight number So stylish: Khloe rocked a white jumpsuit and a matching pair of stilettos, rocking a purple hairdo that she gathered up into a high ponytail Gym bunny: She showed off her incredible curves in the form-fitting outfit Following on from Kylie's dazzling appearance, Kim was in a floor-length pink turtleneck gown with full sleeves, showing off her chiseled figure in the skintight number.
