PDO threads are dissolvable polydioxanone sutures placed under the skin to lift and tighten. They're one of the few treatments that do two things at once: reposition tissue immediately and rebuild the skin's support structure over time. Here's what that means in practice.
1. An Instant, Visible Lift
Barbed "cog" threads hook into the tissue under the skin. When the practitioner gently tensions them, sagging jowls, cheeks or brows are lifted into a more youthful position before you leave the chair. Injectables and energy-based devices can't do this. They either add volume or tighten gradually over months.
Expect some swelling to exaggerate the lift at first. The result settles into its natural position over one to two weeks.
2. Long-Term Collagen Stimulation
This is the "secret" behind PDO threads. Your body recognises each thread as a tiny, controlled injury and responds by sending fibroblasts to build fresh collagen and elastin along its path. That's collagen stimulation at work.
The result is skin that becomes firmer, thicker and smoother over two to three months. This improvement continues even after the threads have completely dissolved, at around six months.
3. A True Non-Surgical Facelift with Minimal Downtime
A PDO thread lift needs no incisions, stitches or general anaesthesia. It's done under local anaesthetic in 30–60 minutes, and most people return to work within a day or two. That's why it's so often described as a non-surgical facelift.

4. Natural-Looking, Long-Lasting Results
Because so much of the improvement comes from your own collagen, results look like you, just fresher. There's no "overfilled" look. Most patients enjoy their results for 12–18 months, and regular maintenance sessions can extend the benefit over time.
5. Versatile and Easy to Combine
PDO threads treat a wide range of concerns across the face and body:
- Jawline definition and jowl reduction
- Cheek and midface lift
- Softening nasolabial folds and marionette lines
- Brow lift (a subtle "fox eye" lift)
- Neck laxity and horizontal neck lines
- Crepey skin on the arms, abdomen and knees
They also pair well with dermal fillers, anti-wrinkle injections and skin-quality treatments such as microneedling, so they fit easily into a complete facial rejuvenation plan.
The Honest Limitations
No treatment is perfect. PDO threads won't match the dramatic, decade-long result of a surgical facelift, and they're less effective for very heavy or severely lax skin. Temporary bruising, swelling, tenderness and minor asymmetry are common. Less often, patients experience dimpling, a palpable thread or thread extrusion. An experienced practitioner minimises these risks.
Bottom line: if you have mild to moderate sagging and want a real lift without surgery, PDO threads offer one of the best balances of results, recovery and cost available today.
