Sofia Richie "religiously scrubs" her make-up off at the end of the day.
The 20-year-old model - who is dating Kourtney Kardashian's ex Scott Disick - has revealed that the secret to her flawless complexion is spending a long time washing her face every night to prevent future "break-outs".
Speaking to Vogue Australia, Sofia said: "I'm just religious about really taking off my makeup. I'll just sit there with a cloth even though nothing else is coming off at the end of the night, rubbing everything.
"Falling asleep in your make-up is -- well, you might as well just keel over and say goodbye to your skin forever.
Sofia - who is the daughter of 69-year-old singer Lionel Richie - admitted that her friends can never tell if she's wearing a full face of make-up because her skin " is so good".
Sofia added: "Make-up breaks me out bad. I have to scrub and scrub. But my skin is good, thank god. I don't know why everyone thinks that I don't wear make-up, but I just don't think that anyone can tell. Like, I'm wearing a lot!
"I'll put on a full thing of make-up in the morning and everyone will be like 'Oh bare face?' And I'm like - not really! But thank you, I guess?"
The rising star also confessed her style is based entirely on "comfort" and dressing for herself rather than other people.
Sofia said: "I like to be very casual and comfortable. I like to have like a comfort zone that I stay within, so it's really just about comfort,"
"I love little knit cotton dresses that are very simple. It's hot, easy, cute. I also like, I just got these silk sets, cause they're very light."
