What Are PDO Threads Made Of? Safety, Dissolving Time & Recovery Explained
PDO thread lifts have become one of the most popular non-surgical options for lifting and tightening the skin, but it's completely understandable to want to know exactly what's being placed beneath your skin before committing to treatment. What are PDO threads actually made of, are they safe, and what does recovery really look like?
In this guide, we're answering those questions clearly and honestly, so you can feel fully informed before your consultation with RejuvenationByVienna in Caloundra.

What Are PDO Threads Made Of?
PDO stands for polydioxanone, a synthetic, biodegradable polymer that has been used in medicine for decades. Long before it became popular in cosmetic thread lifting, PDO was already a trusted material in surgical sutures, used to close incisions in everything from cardiac to abdominal surgery.
Because PDO is fully synthetic rather than derived from animal or human tissue, it carries a very low risk of allergic reaction or rejection. Once inserted beneath the skin, the material is gradually broken down by the body through a natural process called hydrolysis, where water molecules slowly break the polymer apart until it's fully absorbed.
Is PDO Thread Safety a Genuine Concern?
Like any cosmetic procedure, PDO thread lifts carry some risk, though serious complications are uncommon when treatment is performed by a properly trained and experienced practitioner. Because the material is biocompatible and has such a well-established history in medicine, PDO threads are generally considered a safe, well-tolerated option for most people.
That said, safety always comes down to more than the material itself. Key safety factors include:
Working with a practitioner trained specifically in thread lift techniques and facial anatomy
Using genuine, sterile, single-use PDO threads sourced from reputable suppliers
A thorough consultation to confirm you're a suitable candidate, with no contraindicating medical conditions
Following aftercare instructions carefully to minimise the risk of complications
How Long Do PDO Threads Take to Dissolve?
One of the most common questions we hear is how long the threads themselves remain in the skin. The threads are fully absorbed by the body within approximately four to eight months, depending on the specific type of thread used and individual factors like metabolism.
Importantly, the visible lifting and tightening benefits of treatment often continue well beyond this point. As the threads dissolve, they stimulate the body's own collagen production in the surrounding tissue, meaning the structural benefits of treatment can continue to build for up to twelve to eighteen months after the threads themselves have fully disappeared.
What Does Thread Lift Recovery Actually Look Like?
Recovery from a PDO thread lift is generally straightforward, though it's helpful to know what's normal so you can feel confident in the days following treatment.
First Few Days – Mild swelling, tightness, redness, or minor bruising at entry points is common and typically settles within three to seven days.
First Two Weeks – A subtle pulling or tugging sensation as the threads settle is normal and usually fades within one to two weeks.
Two to Four Weeks – Most swelling has resolved, and you'll begin to see your results settle into their more natural, final appearance.
Ongoing – Continued collagen stimulation gradually enhances firmness and structure in the treated area.
Most people return to normal daily activities within a day or two, though your practitioner will provide specific guidance based on the number and placement of threads used.
Tips for a Smooth Recovery
Avoid excessive facial movement, massaging, or rubbing the treated area for the first one to two weeks.
Sleep on your back where possible to avoid unnecessary pressure on treated areas.
Avoid dental work, facials, or other facial treatments for several weeks following your thread lift.
Skip strenuous exercise for at least a week to minimise swelling.
Follow any specific aftercare instructions provided by your practitioner closely.
Frequently Asked Questions
Are PDO threads the same material used in dissolvable stitches?
Yes, PDO is the same type of material that has long been used in absorbable surgical sutures, which is part of why it has such a well-established safety profile.
Will I be able to feel the threads under my skin?
Some people notice a mild tightness or awareness of the treated area in the first one to two weeks, but this typically settles as the threads bed in and swelling resolves.
What happens once the threads fully dissolve?
The threads themselves disappear completely, but the collagen they've stimulated remains, continuing to support the skin's structure well beyond the dissolving timeline.
Feel Informed Before You Treat
