EnjoyPhoenix is a popular member of France's thriving YouTube community, but she apparently had no idea what kind of trouble she was laying out for her 2 million subscribers.
In one of her most recent videos, she recommended a natural face mask made up of "everyday ingredients you can find in the cupboard".
One ingredient was cinnamon, which can be harmful when it comes into contact with some people's skin.
Unaware of this, the 20-year-old YouTube sensation recommended the mixture as a method for making one's skin look more supple.
However, soon after she uploaded the video (above), her loyal fans started to complain.
"The cinnamon burns and I'm suffering the consequences," wrote one, according to newspaper L'Express
"Sure, I have soft skin, but my cheeks are on fire and they're as dry as straw."
French newspaper 20 Minutes confirmed with a dermatologist that cinnamon wasn't just dangerous for soft skin, but could prompt allergic reactions from some.
The YouTuber took to her Facebook page on Wednesday afternoon in a defensive rant at her critics where she said she had used the cream for years, and that the recipe was "as old as the world".
She also took the chance to remind the world that she is only 20 years old, and that even though she knew it was her choice to be in the public eye, she was sick of being criticized.
