When it comes to the latest TikTok life hacks, you often wish people would just shut their mouths—literally. Thankfully, that’s exactly what the newest trend is all about! Guys are being encouraged to tape their mouths shut while they sleep to supposedly get a better jawline.

Part of me is hella suspicious that women might be behind this to cut down on snoring or sleep talking, and honestly, I wouldn’t even blame them. While doctors are skeptical, it’s not likely to hurt anyone to try.

As for me, it’s a no-go. Even at 28, my mustache grows in like a 13-year-old’s, and I’m not about to lose what little peach fuzz I have!
