Polydioxanone (PDO) is a strong, synthetic monofilament thread that is biodegradable. PDO threads have been used by surgeons as cutaneous and subcutaneous sutures for over 30 years. Today, PDO threads are being used on the face and body to provide contour, volume, and improvement of skin texture. The threads are inserted using a small flexible needle and are left in the skin to initiate the formation of an optimal amount of new collagen and elastin. After some time, wrinkles will start to smooth, facial color can improve, pores can narrow, and skin becomes more elastic. The skin tissue improves monthly due to collagen formation around the dissolvable threads. The final result lasts around 12-24 months, depending on the age and health of the individual. PDO threads can also create a lifting effect, depending on what type of thread is used. They can be used on your face or neck area to give a slight lift that will give you a more youthful look. Your PDO specialist will work with you to decide on the best and most appropriate treatment for you.
