Lip arch patent

The labial red line of the upper lip is arched, which is called labial arch. Slightly below the center line, slightly protruding forward is called kerf (kerf). The highest point of the labial arch on both sides is called the labial peak. The middle lip of the upper lip is red and beaded, which is called lip bead. The longitudinal groove extending from the nasal columella downward to the middle of the upper lip skin surface is called Renzhong. If the basic shape of lip bead's lip peak is not perfect, Tian Yongcheng can use its own patented technology to solve this problem. The method is: self-organizing tunnel transplantation technology.
