Thread lift guide: PDO threads, candidacy, realistic results, and risks

Thread lifts are one of the most overhyped and under-explained treatments in medical aesthetics. They produce real but modest results — and the gap between marketing claims and realistic outcomes is larger here than almost any other procedure. Here's an honest guide.

What thread lifts do

PDO (polydioxanone) threads are absorbable sutures inserted under the skin via cannula or needle. They have two effects:

Mechanical lift: Barbed ("cog") threads have tiny barbs that anchor to subcutaneous tissue. When the thread is pulled, it physically gathers tissue and holds it in a lifted position. This immediate mechanical lift is the most visually dramatic part of the result.

Collagen stimulation: PDO threads stimulate a foreign body response — the body surrounds the thread with new collagen. As the thread absorbs (over 6 months), the collagen scaffold persists, improving skin firmness and texture in the treated area.

Thread types:
Cog/barbed threads: Provide mechanical lifting; used for jowl, midface, and brow lifting
Smooth/mono threads: No barbs; no lifting; purely collagen stimulation; used for skin quality in the cheeks, neck, décolletage
Screw/twist threads: Enhanced surface area for collagen stimulation; skin quality focus

Realistic results

This is where thread lifts are most often misrepresented:

What thread lifts can realistically achieve:
2–5 mm of lift in the jowl area
Subtle improvement in jawline definition
Modest improvement in nasolabial fold depth
Mild lift in the brow (1–3 mm)
Improved skin quality and tightness from collagen stimulation (especially smooth threads in neck/cheeks)

What thread lifts cannot achieve:
The result of a surgical facelift — the level of lift is fundamentally different
Removal of excess skin
Treatment of significant skin laxity
Permanent results — PDO threads absorb in 6 months; the collagen effect may last 1–2 years

Duration: Most patients see results for 12–18 months. Some providers claim 2 years; this is the outer range for the collagen stimulation component. The mechanical lift begins to relax as the threads absorb.

Ideal candidacy

Thread lifts produce the best results in a narrow patient profile:

Best candidates:
Early jowling — tissue is starting to descend but there's not significant excess skin
Mild to moderate laxity in the midface or lower face
Good skin quality (adequate collagen and elasticity to hold threads)
Patients who are not yet facelift candidates but want to address early descent
Typically: 35–55 years old with early facial aging

Not appropriate for:
Significant skin excess — threads cannot remove skin; the gathered skin creates puckering rather than a clean lift
Significant submental fat combined with laxity — fat reduction (liposuction, Kybella) should precede or accompany thread work
Very thin skin — thread visibility and extrusion risk is higher
Patients who are facelift candidates — threads will not achieve an equivalent result and may actually complicate future surgery by creating scar tissue adhesions

The procedure

Topical or injected local anesthesia
Entry points created (small punctures) at the temple, hairline, or other anchor points
Threads inserted via cannula or needle, following mapped vectors
Barbed threads are pulled to lift tissue
Thread ends are trimmed and entry points closed

Time: 45–90 minutes depending on area coverage.
Downtime: 3–7 days of swelling, bruising, and skin dimpling at entry points. Puckering immediately post-procedure normally resolves in 1–2 weeks as the threads relax and the tissue redistributes.

Risks and complications

Thread lifts have a higher complication profile than many non-surgical treatments. Patients should understand these before booking:

Common (expected):
Visible dimpling or puckering at thread entry points (usually resolves in 2 weeks)
Asymmetry requiring adjustment
Mild soreness and restriction of facial movement for 1–2 weeks

Uncommon but meaningful:
Thread extrusion: A thread migrates to the surface and pierces the skin. Requires thread removal. Risk is higher in thin skin, superficial placement, or infection.
Infection: Any subcutaneous foreign body can develop infection. Signs: persistent redness, warmth, swelling, fever. Requires immediate evaluation.
Nerve injury: Incorrect depth can injure superficial branches of facial nerves. Rare with experienced providers.
Migration: Threads (especially smooth types) can migrate from the intended location, causing visible lumps under the skin.
Facial nerve proximity: The facial nerve branches run through the same subcutaneous plane where threads are placed. Permanent nerve injury is rare but documented in inexperienced hands.

Long-term consideration: If a patient eventually pursues a facelift, prior thread placement can create scar tissue adhesions that complicate the surgical dissection plane. Inform any future surgeon about prior thread work.

Thread lifts vs surgical facelift

| Factor | Thread Lift | Surgical Facelift |
|---|---|---|
| Lift magnitude | 2–5 mm | 10–20 mm+ |
| Skin removal | None | Yes |
| Duration | 12–18 months | 5–10 years |
| Downtime | 3–7 days | 10–14 days |
| Anesthesia | Local only | General or deep sedation |
| Complication risk | Moderate (extrusion, asymmetry) | Higher (bleeding, nerve, scar) |
| Cost | $1,500–$4,000 | $8,000–$20,000+ |
| Best for | Early aging, not-yet-surgical | Moderate to significant laxity |

The key question: Am I a thread lift candidate, or am I a facelift candidate who would be better served by surgery in 1–2 years? An honest provider will tell you if you've crossed the threshold where threads won't deliver meaningful results.

Combined approaches

Thread lifts are often most effective when combined with:
Filler: Volume restoration (cheeks, temples) repositions tissue to work with the mechanical lift
Ultherapy/Sofwave: Deeper skin tightening complements the thread lift and extends results
Botox: Relaxing downward-pulling muscles (DAO, platysma) complements the upward vector of thread work

A comprehensive plan often produces better results than threads alone.

Questions to ask before booking

Based on my degree of laxity, am I a good thread candidate, or would I be a facelift candidate who'd be disappointed with threads?
How many thread cases do you perform monthly? Can I see your healed results at 6 months (not just immediate post)?
What is your extrusion and complication rate?
If I plan to have a facelift in 3–5 years, how does thread work affect that surgery?
Which thread type and vector do you recommend for my specific anatomy?
