A growing social media trend encourages individuals to tape their mouths shut, purportedly to sculpt a more defined jawline, and is gaining popularity within online “looksmaxxing” communities [[1]]. Despite endorsements from some online influencers, including Saskia on Instagram [[1]], medical experts warn the practice lacks scientific backing and may pose health risks. This report examines the claims behind mouth taping and the potential dangers associated with attempting to alter facial structure through this unproven method.
A social media trend promoting mouth taping as a way to achieve a more defined jawline is gaining traction, particularly within online communities focused on physical self-improvement. Influencer Saskia has described the practice as a “lifehack” and shared her positive experiences with the method on Instagram. The trend is especially popular within the “looksmaxxing” community, where individuals, often young men, explore ways to enhance their appearance.
No Scientific Evidence
Currently, there is a lack of robust scientific research demonstrating that mouth taping effectively alters bone structure or jawline definition in adults. A search of Google Scholar, a database specializing in scholarly literature, yielded no relevant results supporting these claims.
This absence of evidence is confirmed by Brecht Moerenhout, a pharmacist and medical editor at Gezondheid en Wetenschap. “I have found nothing on this topic in the scientific literature,” Moerenhout stated. He added, “There are techniques that can influence facial structure at a young age, but there is no evidence for adults, and certainly not in the case of mouth taping.”
Facial Structure Stabilizes with Age
Facial structure can still change in children because their bones are still growing and malleable. Prolonged mouth breathing, as opposed to nasal breathing, can negatively impact facial and dental development in children. However, this refers to consistent mouth breathing over months or even years, not occasional instances.
In children, these issues can potentially be addressed with medical and orthodontic interventions. Persistent mouth breathing is often caused by an obstruction in the nasal passages, which should be treated first. It’s important to address the underlying cause of mouth breathing to ensure proper development.
For adults, facial structure is largely fixed, meaning lasting changes typically require surgical procedures. Various specialists offer jawline correction options, ranging from temporary solutions like fillers and Botox to more invasive procedures such as facelifts. This highlights the limitations of non-surgical methods for altering established facial contours.
Potential Risks of Mouth Taping
Moerenhout cautions that mouth taping isn’t without risk. “If you are not used to breathing through your nose, or if your nose is blocked, you simply cannot breathe properly. You won’t get enough oxygen.” He emphasized that mouth taping doesn’t address the root cause of breathing difficulties. “In this way, you are actually worsening your airflow. The problem often lies in the nose, not the mouth.”
The use of mouth tape carries potential risks. Individuals with nasal congestion due to allergies, colds, or anatomical abnormalities may experience shortness of breath. For those with sleep apnea or lung problems, mouth taping could be harmful as it restricts airflow. These pre-existing conditions require careful consideration before attempting such practices.
The Bottom Line
Mouth taping is being promoted online as a method to improve jawline definition, but there is no scientific evidence to support these claims. The facial structure of adults is largely set, making significant changes without medical intervention unlikely. Furthermore, using mouth tape can be risky, potentially hindering breathing and exacerbating underlying health conditions. This trend underscores the importance of critically evaluating health claims found on social media and consulting with healthcare professionals before trying new practices.
