What Is a Liquid PDO Thread Lift?
A Liquid PDO Thread Lift — also referred to as a liquid thread lift, PDO collagen biostimulator treatment, or non-surgical thread lift — is a minimally invasive injectable procedure using polydioxanone in liquid micro-particle form. Rather than mechanically lifting tissue through inserted threads, this treatment triggers the body’s wound-healing response: stimulating fibroblasts to produce new collagen and elastin fibres in a process known as neocollagenogenesis.
The PDO material used at Glowwis is approved by the KFDA (Korea Food and Drug Administration), which has independently evaluated the formulation’s biocompatibility and safety profile. PDO is gradually metabolised and eliminated by the body, leaving no permanent residue. PDO’s use in surgical sutures spans more than 30 years of documented clinical application.
This positions the Liquid PDO Thread Lift as a 4th-generation collagen biostimulatory treatment — distinct from dermal fillers (which add volume through material deposition) and from traditional thread lifts (which provide mechanical support through physical thread insertion).
