Do PDO threads work? What to really expect
PDO threads work for what they set out to do, and disappoint when they promise more than that. They can give a discreet repositioning of tissues and improve skin quality in people with mild to moderate sagging. They do not do what a surgical lift does, and the lifting effect tends to be temporary.
A good part of the bad reputation of threads comes from wrong expectations, not from the material. This page helps you explain honestly what to expect, who they tend to suit, and when the best answer is to point to another path.
What are PDO threads?
PDO is polydioxanone, an absorbable polymer used for decades in surgical sutures. In orofacial harmonization (HOF), it appears in fine threads inserted under the skin, which the body absorbs over months. Broadly, there are two groups:
- Smooth or spiral threads: act mainly by stimulating collagen around the thread, focused on skin quality and firmness.
- Barbed threads (with spicules): anchor into the tissue and allow some repositioning. These are the lifting threads proper.
The choice of type, number and direction belongs to the qualified professional, based on assessment and the rules of their board.
What can threads do and not do?
| What they can do | What they do not do |
|---|---|
| Discreet repositioning of tissue in mild to moderate sagging | Remove excess skin |
| Improve definition of the jawline in selected cases | Replace a surgical lift in pronounced sagging |
| Stimulate collagen around the thread | Replace lost volume like a filler |
| Complement toxin, filler and biostimulator | Give a permanent result |
| Usually have a shorter recovery than surgery | Be free from risks and discomfort |
The central point is the type of concern. Sagging is different from volume loss: a face that is "dropping" because of fat loss and loss of bone support may need more support from filler than from threads. And sagging with significant excess skin is surgical territory.
Who do threads tend to suit?
In general, the profile that benefits most:
- Mild to moderate sagging, with skin of reasonable thickness.
- A patient who wants a discreet improvement and accepts maintenance.
- A patient who understands that threads are usually part of a combined plan.
And the profile in which the result tends to be limited:
- Pronounced sagging, with excess skin in the neck and under the chin.
- Very thin or very heavy skin.
- Expecting a surgical result or an effect that lasts "forever".
Assessment of the lower third, where threads show the most, is in lower-third sagging. The layers involved, such as the SMAS and the retaining ligaments, are in facial aging by layers.
When does the result appear, and how long does it last?
The repositioning from barbed threads is usually noticed right away, but the real look only shows after the swelling and pulling of the first days pass. Collagen stimulation is gradual, over weeks to months. The thread is absorbed over months, and the effect may last a little beyond that. The full timeline depends on the thread type and on each patient.
What are the risks and discomfort?
In the first days, pain, pulling, swelling and bruising are common, along with small irregularities that tend to improve. Less common: asymmetry, dimpling, a palpable or visible thread, infection and the thread coming out through the skin (extrusion). All must be included in the informed consent. The patient guidance template, with the warning signs, is in post-PDO thread instructions.
Threads or biostimulator?
Both stimulate collagen, but in different ways: the thread adds some mechanical repositioning, while the collagen biostimulator acts more diffusely on quality and firmness. Many plans combine the two. The comparison is in biostimulator or PDO threads, and the realistic expectation for the biostimulator in does the biostimulator really work?.
Where does Harmy come in?
Harmy does not simulate threads. The projection works with filler and toxin at the marking points, such as Jawline and Cheekbone. In patients with a "sagging face" complaint, it can help show how much of the problem is volume and support, which filler usually treats, and how much is sagging, which is left for your explanation at the consultation.
Frequently asked questions
Do PDO threads really work?
They can work for the right goal: discreet repositioning and improved skin quality in mild to moderate sagging. They do not replace surgery in pronounced sagging, and the lifting effect tends to be temporary.
Are PDO threads worth it?
They are worth it for those with an indication and realistic expectations. For pronounced sagging, excess skin or anyone expecting a surgical lift effect, other options are usually more suitable. The decision comes from the assessment.
Are PDO threads good for sagging?
For mild to moderate sagging, they can help, especially combined with other tools. In pronounced sagging, the result tends to be limited and short-lived.
Do PDO threads give a lifting effect?
Not in the surgical sense. Barbed threads can give a discreet, temporary repositioning of tissues, and smooth threads act more on skin quality.
