The PDO suture, or thread, is a synthetic and biodegradable monofilament suture which was developed in the 1970’s. MIRACU PDO Thread treatments are well tolerated by patients and typically require little to no down time. MIRACU PDO THREADS® remain in the body up to 240 days. Thereafter, the PDO suture is then converted into water and carbon dioxide, and is fully absorbed without any residue, through a process known as hydrolysis, during which time the synthesis of new collagen production in the treatment begins, allowing skin to present fewer wrinkles, thus improving the skin’s overall texture and youthfulness.
