The TikTok Viral Double Chin Exercise That Experts Warn Against

Targeted ads and algorithms follow us into the depths of REM sleep cycles, convincing our dream selves that we really do need the sunrise alarm clocks and viral dresses to be happy. TikTok's algorithm is no different, as it's known to be extremely accurate in giving you exactly what you want to see (via In The Know). TikTok's "For You" page seems to listen in on mundane conversations, random exclamations and your deepest darkest thoughts before producing a stream of relevant content.

The hashtag #TikTokmademebuyit has 4.8 billion views, proving that users are influenced (and know they're being influenced) by TikTok when they buy things. For those on HealthTok, jawline exercisers became one such purchase, showing up on many FYPs for their magical ability to define jawlines. Many creators swear by the device — but experts aren't in agreement with them.

Read on to know why you shouldn't use these devices and why you shouldn't take medical advice from TikTok.

The jawline exerciser can be dangerous

"#Jawline" has 1.3 billion views and majority of the top videos on this hashtag give viewers 'quick fixes' for jawlines that aren't perfectly chiseled, perpetuating another very specific insecurity. Celebrity jawlines from Kylie Jenner to Margot Robbie are idealized, and techniques ranging from chewing gum to using a jade roller have become popular ways to get those jawlines. The jawline exerciser is another product made to target this insecurity.

According to Health, one user promoted a jawline exerciser in a since-deleted video, claiming to get "rid of [her] double chin in 57 days" after chewing on it for 30 minutes a day. Many other users corroborated her story, showing their own results after using the product.

Mark Wolff, the dean of the University of Pennsylvania School of Dental Medicine told Health, "This is an incredibly dangerous item for the health of your front teeth" as it can bend it out over prolonged usage. He also said that it's a "crazy device" and is unlikely to produce the results influencers have touted as it bulks up the muscles in the jawline instead of cutting down on any fat. The device can also cause pain in the joints in your jaw while increasing stiffness and limiting movement. In conclusion: before TikTok makes you buy it, do your research.
