In 2019, Tomazzo helped spark massive interest in jawline training and “mewing” transformations online on Youtube. Determined to experiment with facial development techniques, he ordered Stronger Gum directly from the factory years before the product officially launched to the public.
His dramatic transformation videos quickly went viral across YouTube and social media, with viewers amazed by the visible changes in his jawline, facial definition, and overall appearance. At the center of his routine were two key habits: consistent chewing and proper tongue posture: the foundations of mewing.
Mewing is a technique popularized by Dr. John Mew and Dr. Mike Mew that focuses on maintaining correct tongue posture by resting the tongue fully against the roof of the mouth while breathing through the nose. Supporters believe this posture can contribute to better facial structure, stronger jaw development, and improved oral posture over time, especially when combined with healthy habits.
Chewing also plays an important role in facial muscle engagement. Modern diets are much softer than those of previous generations, which means the jaw muscles often receive less stimulation.
Tomazzo’s early experiments combining mewing, hard chewing, and consistent discipline became one of the first major viral examples of the modern looks movement online. His videos helped introduce millions of people to the concepts of tongue posture, facial development, and functional chewing long before the topic became mainstream.
