Her love of makeup is well-know. Indeed, there are those who have suggested that 17-year-old Kylie Jenner's heavy look is inappropriate for her age.

Certainly, her dark smoky eyes, highlighting and contouring, and – of course – her famously lined and glossed pout are designed to make a big impact. 

And although the California-native has been previously photographed out and about without her usual layers of foundation, she's never posted a makeup-free selfie.

Until now, that is.

Taking to Instagram, the teenager shared the unusual snap. In in she can be seen on a private plane – her skin appears entirely clear and clean of makeup.

Ms Jenner, who was on the way to Miami at the time, looks remarkably pretty and youthful, her big brown eyes in particular standing out.

Her fans evidently liked her new look too: within four hours, the snap notched up 850,000 likes.

Earlier this year, the reality TV star revealed that she loves to indulge 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."

She added: “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."
