Shop If you are considering a non-surgical aesthetic treatment to tighten sagging skin, your most pressing question is likely: How long do PDO threads last?
Unlike a surgical facelift, a polydioxanone (PDO) thread lift offers a temporary, non-invasive alternative to traditional surgery. However, the exact timeline of your results depends on a unique biological process. To help you plan your treatment, here is the direct answer to “How long does a PDO thread lift last?”
The Quick Answer to “How Long Do PDO Threads Last”
The Threads Themselves:
The actual physical PDO sutures will completely dissolve inside your body within 6 to 10 months.
The Visual Results:
The visible lifting and skin-tightening effects typically last anywhere from 12 to 24 months, thanks to the new collagen your body produces while the threads are in place.
The Science Behind the Timeline: Why Results Outlive the Threads
To understand why your visual transformation outlasts the physical threads, it helps to understand what polydioxanone actually does. PDO is a medical-grade, absorbable material that surgeons have safely used for decades. When these threads are strategically inserted into the underlying tissues, they immediately create a mechanical lift.
However, their true power lies in collagen stimulation. Your body recognizes the threads as a benign foreign object and naturally triggers a healing response. This response surrounds the threads with a fresh matrix of type I and type III collagen and elastin fibers. While your body safely absorbs the physical threads via natural hydrolysis within several months, the sturdy structural framework of new collagen remains behind. This newly formed support system keeps your skin looking firm, volumized, and youthfully lifted long after the threads are gone.
