Kylie Jenner may be a beauty mogul, but the 18-year-old doesn't shy away from letting her natural beauty shine every once in awhile!

On Tuesday, the reality star had a "no makeup" day on Snapchat, showing off her product-free face in a series of videos.

But not all fans were convinced the teen's look was completely authentic. One follower tweeted, "I hate how @KylieJenner put on snap all natural today but those are definitely not her natural eyebrows."

Kylie was quick to respond, writing, "Tinting your brows. You should try. Life changing! X"
