Thread lifts explained: PDO and cog threads, results and recovery
A thread lift repositions tissue that has descended. Done well, it is subtle. Done for the wrong face, it is disappointing. Here is how to tell the difference.
What a thread lift actually does
A thread lift uses fine, medical-grade absorbable threads, inserted through a small needle or cannula into the layer beneath the skin. Depending on their design, they do one or both of two things:
- Mechanical lift. Threads with tiny barbs or cones (cog threads) grip the tissue so that it can be gently repositioned upwards and anchored.
- Biostimulation. As the body gradually absorbs the thread, it forms new collagen around it, which improves firmness and skin quality.
It is a way to reposition, not to add volume. That distinction decides whether a thread lift is the right tool.
Types of thread
By design
- Smooth (mono) threads. These are fine and straight, mainly used for skin quality and texture. They provide little lift.
- Screw or twisted threads. These give a little more support to a small area.
- Cog or barbed threads. These are the lifting threads, used along the cheek, jawline and jowls.
By material
| Material | Dissolves over approximately | Notes |
|---|---|---|
| PDO (polydioxanone) | about 6 months | The most widely used thread, with a long safety record |
| PLLA (poly-L-lactic acid) | about 12–18 months | Stronger collagen stimulation |
| PCL (polycaprolactone) | about 18–24 months | Slowest to absorb |
The material dissolving does not mean the result disappears on that day. The new collagen and repositioning persist for a while afterwards, but gradually soften with time.
Who is a good candidate?
A thread lift tends to work best for people with:
- mild to moderate sagging of the mid-face, jowls or jawline
- reasonable skin thickness
- realistic expectations of a refreshed, not dramatically changed, look
It is usually less suitable when:
- skin laxity is advanced or the skin is very thin
- the main issue is volume loss (hollow cheeks or temples), which is better addressed with fillers or a collagen stimulator first
- there is active skin infection, a bleeding disorder or certain medical conditions, which should be discussed with the doctor
The procedure
- Consultation and marking. The doctor assesses the direction and degree of descent, then marks entry points and vectors.
- Local anaesthetic at the entry points and along the planned path.
- Insertion. Threads are placed with a needle or cannula. Cog threads are then gently adjusted to lift the tissue.
- Duration. The procedure takes about 30–60 minutes for a typical lower-face treatment.
Recovery: a realistic timeline
| When | What is normal |
|---|---|
| Days 1–3 | Swelling, tightness and tenderness. Some bruising. Puckering at entry points is possible. |
| Days 3–7 | Swelling settles. Most people are comfortable in public. |
| Weeks 1–2 | Mild tightness when chewing or yawning. Small irregularities usually smooth out. |
| Weeks 4–8 | Tissue settles and collagen formation begins. |
For about two weeks, you will usually be asked to:
- avoid opening your mouth very wide, chewing very hard foods, and dental work
- avoid facial massage, facials and strong pressure on the face
- sleep on your back, with your head slightly raised
- avoid saunas, hot yoga and strenuous exercise for the first week or so
Risks to discuss honestly
Most effects are temporary: bruising, swelling, asymmetry, or dimpling where the threads hold the tissue. Less common problems include a thread becoming visible or palpable, extrusion through the skin, infection, or prolonged discomfort. Most of these can be treated, sometimes by removing a thread. Knowing the facial anatomy — where the nerves, vessels and glands lie — is what keeps the risk low.
Threads in a wider plan
Faces rarely age in only one way. A common sequence is to restore lost structure first (for example the chin, cheekbones or temples), then reposition with threads, then refine the skin with energy-based treatment. Doing them in the right order often means using less of each.
A good thread lift is not visible. People notice that you look less tired, not that something is holding your face up.
Frequently asked questions
How long does a thread lift last?
The repositioning effect usually lasts around six to twelve months, and sometimes longer. Threads made from slower-dissolving materials such as PLLA or PCL may stimulate collagen for longer than PDO. Age, skin quality and how much the face moves all play a part.
Is a thread lift painful?
It is done under local anaesthetic, so most people feel pressure and tugging rather than sharp pain. Tightness and tenderness for several days afterwards are common, and are usually managed with simple pain relief.
When can I go back to work?
Many people return to desk work within two to three days. If you want to avoid visible bruising or swelling, allow about a week.
What are the risks?
Common effects are bruising, swelling and temporary asymmetry or dimpling, which usually settle. Less commonly, a thread may become visible or palpable, or extrude, or an infection may develop. These need review by your doctor. Rarely there may be nerve irritation or prolonged pain.
Thread lift or filler — which is better?
They solve different problems. Threads reposition tissue that has slipped; fillers replace volume that has been lost. Many faces need a little of each, and the order matters.
