PDO stands for polydioxanone, which is a synthetic material that is commonly used for surgical sutures in the skin and subcutaneous tissues in various fields such as plastic surgery, gastroenterology, urology, gynaecology and ophthalmology.
PDO is slowly absorbable within the body, and can last 6-8 months in the body. The threads made of PDO for threadlift are either smooth (monofilament), spiraled or hooked.
PDO threads when inserted into the body causes skin lifting, tightening and toning of the skin, causes skin rejuvenation, increases volume and smoothens wrinkles. It is useful for lifting of droopy cheeks, double chin, eyebags. It is also used for what is commonly called the V lift, which is a process by which the normal V-shape of a youthful face which has deteriorated with age and become an inverted V, is now reversed back to a more youthful V.
On the body, PDO threads can also be used for reducing the folds and wrinkles of the neck and decolette and also lifting saggy tissue anywhere, including the breasts.
The interesting thing about polydioxanone is that in the body, it stimulates the production of new collagen. This property adds on to the initial lift created by insertion of threads. Effects can last up to 24 months.
