PDO threads are absorbable threads made from of synthetic material Polydioxanone (PDO).
They completely dissolve in 8-12 months but the rate at which they dissolve depends on the number of factors, such as age, sun exposure, lifestyle etc.
Different studies have comparative results showing these threads retain 90 percent of their tensile strength in first 3 months. In following 3 months the threads’ tiny cracks begin to happen in the periphery of the threads, which is followed by the gradual breakdown of the material by the body. Upon the placement of the threads, they begin to induce local production of collagen, so despite them being fully dissolvable, the collagen production in the treated area provides support to the structures thus providing lasting results.
