Twisted threads are made from PDO or “polydioxanone,” a material used in the field of medicine for decades as part of the manufacture of dissolvable sutures. PDO is one of the safest materials to introduce into the skin.
Is a PDO Thread Treatment with Twisted Threads Painful?
The twisted threads are very fine and thin and are introduced with a blunt cannula for precision placement and increased safety, as the blunt tip of the device pushes blood vessels aside for a lower risk of bruising or bleeding.
Prior to placing the threads, a specially formulated numbing cream is applied, which is more effective than most such creams offered at other med spas. As Dr. Du has a background in interventional pain management, she has this cream specially compounded for her clients.
