As we all know, people's facial expressions are controlled by facial muscles. There are 44 facial expression muscles. By matching blood vessels and bones, a * * * can make more than 5000 kinds of expressions. When we laugh, as many as 17 muscles on our faces move. Among them, the muscles that mainly mobilize facial smile are zygomatic muscle, orbicularis oculi muscle and orbicularis oris muscle. They were pulled together to produce a facial smile.
For those who smile happily and beautifully, we can see several rules: the corners of ta mouth will rise, the corners of risorius will rise, the corners of eyes will sink, and the lying silkworm will bulge. The happier they laugh, the greater the contraction of orbicularis oculi and zygomatic muscles.
And some people can't laugh, or laugh unnaturally. First, because these muscles that control smiles are not sensitive enough, or the degree of activation is not enough, they are particularly cold when they smile.
Second, because of "fake smile", which is also the most common unnatural smile.
We can observe several expressions about laughter in WeChat expressions. Why do we often think that the expression "smile" is yawning? If someone laughs, I always feel that this person is not laughing from the heart.
In fact, in these expressions, whether it is "smile", "laugh", "simple smile", "cute" or "bad smile", the corners of the mouth are all open, that is, the cheekbone muscles are exerting strength, but the degree of opening is different. But the difference between "smile" and other smiling expressions lies in the corners of the eyes, and the rest of the corners of the eyes are bent because of the smile, but only the eyes with the "smile" expression are opened normally, and there is no smile when the eyes look down.
Therefore, the real smile is accomplished by zygomatic muscle and orbicularis oculi muscle, in which zygomatic muscle is controlled by consciousness, while orbicularis oculi muscle can only be activated by real smile.
Some people even say that some smiles have bent corners of the mouth, but others will think that they are smiling because there is a smile in their eyes.
For those who smile with the corners of their mouths bent downward, it is often because the muscles are not used correctly in the process of laughing, which inadvertently dominates the upper orbicularis oris muscle, the lower orbicularis oris muscle and the lower lip muscle, resulting in a smile like a little bitter gourd.
In this case, efforts should be made to activate the zygomatic muscles and often practice saying "eggplant"; Or put a chopstick horizontally in your mouth, gently bite the middle of the chopsticks with your upper and lower teeth, and then laugh. The teeth will be based on the fixed chopsticks, and the strength will be as moderate and natural as possible. At this time, facial expressions and lips will rise just right.
Finally, a good smile is the result of facial muscle interaction. If you want to look good, besides looking good, being happy from the heart is the most important thing. Because no matter how hard the corners of the mouth smile beautifully, the smile in the eyes can't be deceptive.
What should I do if I laugh badly?
mouth
1. Girls who usually smile beautifully and warmly are not cherry mouths in our traditional aesthetic sense. Girls with small mouths themselves will have a feeling of being torn because their lips are deformed after stretching the smiling muscles.
2. When you don't laugh, girls with downward corners of the mouth will rise slightly when you smile, forming a straight line, which is particularly generous and beautiful, while girls with upward corners of the mouth will rise even more when they smile, which will affect the extrusion of Risorius.
