Traditional Chinese medicine calls the method of face lifting pulling or twisting.

It can be regarded as a simple scraping deformation. Scratching refers to pulling the skin with fingers on certain parts of the body or acupoints to achieve the purpose of treating diseases. According to the theory of traditional Chinese medicine, scrapping can promote blood circulation, remove blood stasis, dredge channels and collaterals, and regulate tendons to recover.

From the point of view of western medicine, there is long-term non-metabolized blood in the small blood vessels on the body surface. After blood is squeezed by external force, the blood vessels break and penetrate into the surrounding cells and tissues, resulting in slight traumatic reaction, which can not only promote local blood circulation, but also mobilize the human body to produce stress reaction, activate the nervous system, circulation, hormones, immunity, excretion and other systems, and enhance the human body's disease resistance.
