Polydioxanone threads are the oldest type of suture used in beauty procedures. They do not last as long as PLLA or PCL thread and are less strong than Poly-L-Lactic Acid products. However, they have several major advantages that still make them a viable option for certain situation. This is the only thread material with noticeable fat dissolving effect. Once in place, the PDO thread will not only boost fibroblasts and induce collagen production, but will also safely dissolve fat tissues, allowing it to contour the facial features not only via the mechanical effect of the thread, but by also removing unwanted fat tissues.
PDO threads take only six to twelve months to dissolve, but their posterior effect can last for up to an year after that. Poly-L-Lactic Acid suture is proven to be effective in fine line and superficial wrinkle removal from the skin and has an overall positive effect on skin pores.
3D Cog Threads – stable and rejuvenating
The so-called 3D cog threads are the most stable type of cosmetic suture. They have miniature barbs all around and along the thread line, allowing them to safely attach to surrounding tissues, once applied. This not only prevents the shifting of the thread, but also causes the skin in the area to react to the foreign object by rapidly producing collagen.
