The specific method is: gently hold the person with your index finger and thumb and pull it down vertically. When the upper lip and the lower lip touch lightly, pause for 2 ~ 5 seconds, then release and repeat the above actions.

Usually do it at least 30 times every morning and evening, and you can do training at any time when you are free. Don't pay too much attention, pay attention to the direction of pulling vertically downward, and don't pull outward. In general, training for 6 ~ 12 months will have certain effect.

Other methods to improve the shortening of upper lip besides lip muscle training:

If the lip muscle training is too monotonous to persist for a long time, we can also suggest learning some musical instruments that can train the upper lip, such as China flute, Dong Xiao flute and western flute or piccolo, which can not only cultivate interest, but also promote the development of the upper lip and improve the face shape.
