Do you know about tongue trainers?

10 minutes a day, one month to completely eradicate chin fat! It is a device that assists with 'mewing exercises' by moving the tongue up and down, and it is said to lift sagging chin muscles to create a V-line.

Based on my personal experience

Moving my tongue with my chin lifted up made me feel like my entire focus was completely absorbed in it. Ten minutes felt like an hour. As my jaw joints were stimulated and strengthened, the skin under my chin seemed to lift slightly, but there's no way that the generous double chin I've had my whole life would vanish so easily just from a short tongue workout! However, I was satisfied with the fact that I could do mewing exercises using equipment. It helps you get used to the correct tongue position, allowing you to maintain healthy breathing without breathing through your mouth in your daily life.
