PDO (Polydioxanone) therapy helps to lift tighten sagging skin. This is achieved by introducing absorbable PDO threads into the subcutaneous tissues using fine needles under local anaesthetic. It works by inducing collagen production in response to the micro-injuries caused by the threads, With time, usually three to six months, the threads are absorbed, leaving the skin tighter due to new collagen formation. The procedure can take between 30-60 minutes, depending on the size of the area being treated. There can be some bruising or swelling occasionally, but this usually clears off after 2 to 3 days. While the best effect is seen in about 6 months, the effects can last for 2-3 years. It is used successfully on the face, jawline, neck, nasolabial folds, arms, thighs and abdomen.
