The difference between American line and ordinary line: 1. American thread is thinner and ordinary thread is thicker. 2. The pain of beauty thread suture is low, while the common thread suture process is more painful. 3. The scar left by the suture removal of the American thread is small, and it can be absorbed by itself without suture removal, while the ordinary thread needs suture removal, leaving a more obvious scar.

Beauty line is a common name for catgut line. The disadvantage is that the wound is easy to split if you don't pay attention. Ordinary lines will heal quickly, but the scars that need to be removed are generally more obvious than those left by beauty lines. Almost all beautiful threads are thinner than hair, generally six threads below 0, and its tension is very small, while regular beautiful threads are needle and thread, and the needles are very small and fragile.

Under normal circumstances, the beauty line does not need a doctor to remove the thread, and it can be absorbed and detached by itself. Beauty thread is very thin, almost all beauty threads are thinner than hair, generally six threads below 0, and its tension is very small, while regular beauty threads are needle and thread, and the needles are very small and fragile.

"Beauty thread", to be exact, should be called fiber surgical suture. It is only suitable for suture of blood vessels, nerves and facial skin with very low tension, as well as ophthalmology and fiber surgery. However, for general surgery, the tension at the incision is much higher than the tension that the suture can bear, and it is almost impossible to sew the incision, even if it is stitched, it will crack. Doctors choose stitches according to the tension and characteristics of different parts.
