biodegradable sutures used to lift and tighten skin
Polydioxanone Threads, commonly known as PDO Threads, are biodegradable sutures used in medical and cosmetic procedures to lift and tighten sagging tissues. Made from a synthetic polymer, these threads are inserted into the skin to stimulate collagen production, providing a non-surgical facelift that gradually dissolves over time, typically within 6 months, while the skin's improved structure can last up to 18 months.
