Ordinary sewing thread is usually 1 thread, but thread 4 is stronger, so I personally like to use thread 4 more. As for intradermal suture, the commonly used thread is not ordinary silk thread, but synthetic material. It is best to choose non-absorbable suture. Anyway, the thread will be pulled out in the future. The "tail bridge" of the tail bridge line mentioned upstairs is one of the brands. The models of these threads are generally marked with four "0s", namely "0000". In fact, the four "0s" are also the thinnest lines in the hospital. I asked the instrument nurse in the operating room again, and the line 1 is three zeros, which is "000". Therefore, according to the model's marks, most of the nonabsorbing lines are thinner than the 1 line, but I look at it with the naked eye and think it is still similar.

I repeat, in fact, the beauty needle in the plastic surgery department is relatively thin. . . But that thread is too thin to bear the tension of any incision, so, ah, intradermal suture is useless.
