While some women may be shy to bring up the topic of female facial hair, there is one famous gal who isn’t afraid to speak about the trials and tribulations of waxing – Kelly Osbourne.

On a recent episode of Lopez Tonight, Kelly spoke openly about her mother, Sharon, burning her upper lip in an attempt to wax Kelly’s face when she was 13-years old.

“When I was a kid she got a home waxing kit and I was the crash test dummy,” Kelly told host George Lopez. “The wax was so hot that it burned me… By the time she pulled the wax off, my skin went with it and I had to go to school with a scab mustache.”

And it seems that Sharon’s error had lasting results.

“Now I have a mustache that I have to wax that I blame my mom for!” Kelly added, laughing.

Luckily, at-home waxing kits have advanced since Kelly, now 25, was 13. MOOM Express Pre Waxed Strips for Face and Bikini boast wax that melts with your body temperature, so that you won’t burn your flesh.

However, if you do experience irritation, there are a multitude of products formulated to soothe skin, such as Tweezerman After Tweeze Soothing Cream, which minimizes tenderness after tweezing or waxing your brows.
