Kylie Jenner spends two hours in the shower.
The 17-year-old reality star loves having "pampering days" to relax and take care of her hair and skin.
She said: "I love pampering days. I usually take a shower or bath for about two hours and scrub my whole body.
"I love lotions - whole yoghurt lotions are amazing - and masks. And I put coconut oil in my hair."
The 'Keeping Up with the Kardashians' star takes extra care of the skin on her face and hands because she doesn't want to age prematurely.
She said: "I use a lot of scrubs. I like to use lavender ones before bed because it calms me.
"Taking your make-up off before you go to bed is good, and using sunscreen on your hands and face.
"Khloe [Kardashian] always told me to put sunscreen on my hands because you can tell someone's age from their hands."
The brunette beauty believes more women should go make-up free.
She told Star magazine: "Girls are most beautiful when they're not really wearing any [make-up]. I think it's really pretty when I see girls wearing no make-up."
