Joining sister Kendall Jenner, Laura Whitmore and Paris Hilton at the California weekend bash, the 17-year-old star stashed an array of skin and make-up gems in her bag, including a lip buy that costs just one quid.
'I always carry lip liner, I have around ten different nude lip liners in the bottom of my bag. Then I have Nip + Fab Dragon's Blood Fix Plumping Serum, £19.95, because I love moisturiser. I always have sunglasses, just in case... and Chapstick, £1!' the Kardashian sister reveals.
Kylie, who recently became an ambassador for Nip + Fab after previously raving about the skincare brand, also shared her top beauty tips:
'Always take your make-up before bed! And put sunscreen on your hands and face. You can tell somebody has aged by their hands. Khloe Kardashian, my older sister, told me to always put sunscreen on my hands,' she explains.
With Kylie's advice and Millie Mackintosh's Coachella beauty tips - we reckon 2015 is set to be our most glamorous festival season yet!
