Are dissolvable threads safe?

Dissolvable sounds reassuring, and a careful reader should ask what it is reassuring about. The material has a track record, and it has a schedule.

Save Face states: "PDO threads are fine, dissolvable sutures made from polydioxanone, a material that has been used safely in surgery for many years."

What dissolvable means in time

The same publisher gives the timeline: "PDO threads gradually dissolve over approximately six months, just like dissolvable stitches from surgery." So dissolvable is a process over about six months, not an instant.

Cause and effect: the safety claim in the first quote is about the material, polydioxanone, and its history in surgery. It is a statement about the thread, not a promise about every appointment. The person placing the threads is a separate variable.

Routine versus a reason to call back

A thread that gradually dissolves over the months that follow matches what Save Face describes. Something that does not fit that picture is a question for the provider who placed it.

Wider reading on facial treatment safety

Safety questions about facial treatments go wider than threads. A retrospective study of complications of dermal injectables and a systematic literature review on the safety and potential complications of facial wrinkle correction with dermal fillers show how complications are studied in a neighboring field. The Cleveland Clinic overview of nonsurgical facelift options covers the wider set of nonsurgical lifts.

The question to put to a provider

Ask: "What are these threads made of, and how long should they take to dissolve?" The answer you want is polydioxanone and around six months. If the provider names something else, ask where the safety record for that material comes from.
