PDO stands for Polydioxanone, which has been used in cardiothoracic surgery for decades! It is fully absorbed by hydrolysis within 4 to 6 months and doesn’t create any scar tissue. The foreign body stimulates collagen synthesis, and the skin structure created will hold for another 12 to 15 months. The bad reputation of threads that were used in the past was due to the fact that they weren’t always absorbable and that there were more complications for those who didn’t have any surgical skills. Using PDO solves that issue.
