PDO threads are minimally invasive, absorbable sutures used to support the skin and stimulate natural collagen production. The threads are made from polydioxanone (PDO), a biocompatible material that has been safely used in advanced medical procedures—including cardiothoracic and open-heart surgery—for decades. This long-standing medical use makes PDO one of the safest materials implanted in the body.
During treatment, PDO threads are gently placed beneath the skin using a blunt cannula, without cuts or incisions. The threads are naturally absorbed by the body over approximately 4–6 months and do not leave behind scar tissue. As they dissolve, they stimulate collagen formation, helping improve skin firmness, structure, and overall skin quality. PDO thread treatments offer subtle support and rejuvenation in areas where traditional injectable treatments may have limitations, while preserving natural movement and expression.
