We're so used to seeing the Kardashian sisters all done up for red carpet events with a full glam squad (which can be lengthy process) but just how long does it take them when they're going at it themselves? We drilled Kim and Khloé Kardashian on their typical daily makeup routines.

"If I’m going to do full makeup, it’s going to take me 20 minutes," Khloé tells InStyle. The star, who covered the Oscars red carpet this year for E!, says, "I’m big on eyebrows and mascara. I always have to have my mascara on."

Meanwhile big sister Kim claims she only needs half the time that Khloé requires: "It takes me like 10 minutes to get ready. I love bronzer. Bronzer is everything."

It also helps to have your own makeup line like the pair, who debuted Kardashian Beauty several years ago with Kourtney, their eldest sister. "We have this big Cabana bronzer ($15; and it’s three different tones so it works no matter how tan or pale you are," Kim tells InStyle. "I think that’s key—and a little bit of blush."
