All of the net proceeds from Kylie Jenner's new lip kit 'Smile' will be donated to charity

Kylie Jenner's had a big week on social media. After showing off her new Ferraris and cooking for boyfriend Tyga on Snapchat, the youngest of the Jenner-Kardashian clan took to Instagram to unveil her latest lip kit, called "Smile" — one that's surprisingly different from her 17 other matte shades. 

All of the net proceeds from "Smile" will be donated to Smile Train, an international children's organization working to help those with cleft lips and palates.

"I'm very excited to reveal SMILE, a beautiful pale pink shade that I created in partnership with @smiletrain for #WorldSmileDay," the 19-year-old wrote on Instagram Thursday. "100% of net proceeds will go toward cleft surgery for children in the developing world and I will be presenting a check to them personally. Let's do this." 

This isn't the first time Jenner has partnered with a charity. In July, she collaborated with Sinful Colors to create three limited-edition nail polish shades with proceeds going to the Stomp Out Bulling organization and the Los Angeles LGBT Center. Prior to that, she had launched the #IAmMoreThan campaign on Instagram where she shared the stories of six people who had been bullied. This is all on top of the volunteer work she has done with Los Angeles Mission and Children's Hospital Los Angeles.

And many have taken to Twitter to voice their excitement for her latest philanthropic act.
