Eliminating double chin with finger pressure
Generally speaking, anyone who is a little fatter will have a double chin, but thin people will not have this situation. Some people say that double chins are dignified and auspicious, but young women are unwilling to do so, and they are already too fat.
People who go to work don't exercise enough, and the most lacking exercise is the chin, so as long as they are not careful, they will form a double chin. Because the chin is easy to store fat. Due to insufficient chin movement and muscle relaxation, chin fat gradually accumulates, and in severe cases, a triple chin will appear. I believe you have also noticed that singers are rarely obese and have double chins! This is because they often practice their voices with their mouths open. Raising your voice and practicing singing loudly every day can not only prevent double chin, but also tighten your face and skin.
If you often eat snacks in your diet, it is easy to form a double chin. When eating, chew as fast as possible to give your chin enough exercise. The reason why the chin relaxes is because of aging, and the most important thing is that its water is reduced. Colloids near cells will absorb water, making skin beautiful and delicate. The more hydrophilic the colloid is, the younger the chin will be. On the contrary, if the colloid is weak in hydrophilicity, the skin is easy to be rough, and a double chin will soon appear.
Double chin can be treated by exercise and massage, and patting chin with cold water when washing your face can also help muscle contraction. These methods can be used simultaneously with acupressure.
