PDO threads treatment is a non-surgical treatment that helps reduce the appearance of sagging tissue by repositioning the skin with the use of a synthetic biodegradable monofilament suture made of Polydioxanone (PDO). This treatment also promotes collagen production and neovascularization to provide a more youthful appearance. PDO threads can treat different areas such as the neck, jowls, jawline, nasolabial folds, eyebrows and marionette lines. It can be used on its own or in combination with other treatment modalities.
