In short. Dimpling and thread visibility are the characteristic complications of a thread lift. Dimpling is skin drawn inward where a thread engages it; visibility is the thread or its line of pull showing under thin or animated skin. Both are mechanical, both are more likely with thin skin or too many threads, and some need release rather than patience.
Key points
- Thread lift complications are mechanical: they come from pulling and holding tissue.
- Dimpling is skin drawn inward at the point where a thread engages it.
- Some dimpling settles over the first weeks; persistent dimpling may need release.
- Visibility is more likely in thin skin, superficial placement and too many threads.
- Infection, extrusion, a broken thread or visible tenting need review rather than patience.
Why are thread complications mechanical?
A thread lift carries complications that are particular to it, and they are mechanical rather than chemical: they arise from pulling tissue and holding it, not from what is placed in the skin. That is why they show up as dents, visible lines and gathering rather than as a reaction to a substance.
Dimpling
The threads engage the tissue, and where they engage it the skin can be drawn slightly inward. That produces a small dent or a puckered area, and it is the characteristic complication of the treatment. Some dimpling settles as the tissue relaxes over the first weeks, and a clinician may plan around it by choosing where the engagement points sit. Where it persists, it may need to be released rather than waited out, which is a further procedure.
Visibility
Threads can be felt or seen under the skin, particularly in thin skin and particularly when the face is animated. The line of pull can also become visible where the tissue has been drawn together. Visibility is more likely where the material is placed too superficially, where the skin is thin, and where more threads are used than the tissue tolerates. It is one of the reasons that the amount of material used is a judgement about the face rather than a number.
Asymmetry and bunching
Almost every face is asymmetric before treatment, and a lift can make a pre-existing difference more apparent while swelling is present. Bunching, where skin gathers because tissue has been drawn together, is the mechanical consequence of lifting a face that had excess skin to begin with. It is one of the reasons significant excess skin is a reason not to use threads.
What needs an intervention?
Most thread complications are managed by reviewing them and, where necessary, releasing or removing material. A small number need attention sooner. Infection at a thread site presents as spreading redness, warmth, pain or discharge, and it needs treating rather than watching. Extrusion, where the material works its way through the skin, needs review and usually removal. A thread that breaks or that is visibly tenting the skin is also a reason to be seen rather than to wait.
The treating team should be contacted for spreading redness, warmth, pain or discharge at a thread site, or a fever; for material becoming visible through the skin or the skin breaking down over it; and for marked asymmetry, dimpling or bunching that is not settling, which is reviewed for possible release.
| Problem | How it presents | What tends to happen | What to do |
|---|---|---|---|
| Dimpling | A small dent or puckered area where a thread engages the skin | May settle as the tissue relaxes over the first weeks | Review; persistent dimpling may need release |
| Visibility | A thread felt or seen under the skin, especially in thin skin and on animation | More likely with superficial placement or more threads than the tissue tolerates | Review the plan; the amount is a judgement about the face |
| Asymmetry | A pre-existing difference looks more apparent while swelling is present | A lift can make the difference more apparent | Review at a planned appointment |
| Bunching | Skin gathers because tissue has been drawn together | The mechanical consequence of lifting a face with excess skin | A reason not to use threads where excess skin is significant |
| Infection | Spreading redness, warmth, pain or discharge, or a fever | Needs treating rather than watching | Contact the treating team |
| Extrusion | The material works its way through the skin | Needs review and usually removal | Contact the treating team |
| Broken thread or visible tenting | A thread breaks or visibly tents the skin | Needs to be seen rather than waited out | Contact the treating team |
Which faces carry the higher risk?
Thin skin, a face that has been treated before, and a plan calling for a large number of threads are all factors that raise the chance of visibility and dimpling. A clinician who names those factors in advance is describing your face rather than the treatment in general, and it makes the conversation about the plan considerably more useful.
What should you ask before treatment?
Ask what the plans are for dimpling, visibility and asymmetry, and who to contact if any of them appears. A clinician who describes how each would be managed has thought about the complications the treatment actually produces.

Frequently asked questions
What is dimpling after a thread lift?
It is the skin being pulled slightly inward at the point where a thread engages it, and it appears as a small dent or a puckered area. It is the characteristic complication of the treatment. Some dimpling settles as the tissue relaxes over the first weeks, and some persists, in which case it may need to be released rather than waited out.
Can the threads be felt or seen?
They can be, particularly in thin skin, and particularly when the face is animated. Visible or palpable threads are more likely where the skin is thin, where the material is placed too superficially, or where the number of threads used is greater than the tissue tolerates. It is one of the reasons the technique and the patient's skin quality matter more than the number of threads.
When does a thread problem need urgent attention?
Infection and extrusion do. Signs include spreading redness, warmth, pain, discharge, or the material becoming visible through the skin. A thread that has broken or that is tenting the skin visibly also needs review rather than patience. Asymmetry and dimpling are usually reviewed at a planned appointment rather than urgently.
Risks & Limitations
- Dimpling after a thread lift, where the skin is drawn slightly inward at the point a thread engages it. Some settles; some persists.
- Thread visibility, where the material or the line of pull can be seen or felt under thin skin, particularly when the face is animated.
- Asymmetry between the two sides, and bunching where tissue has been drawn together in a face with excess skin.
- A thread that becomes infected, extrudes through the skin or breaks, each of which needs review and usually removal.
- Bruising and swelling after either treatment; with filler, swelling can be marked for several days and changes the shape of the area until it settles.
- Lumps, irregularity and delayed reactions after filler, and rarely a vascular occlusion, which is a medical emergency.
- Filler placed into tissue that has descended can make the face look heavier rather than fresher — a planning error rather than a complication.
- Both treatments are temporary. Threads are absorbed and the lift fades; filler is broken down over months. Neither stops ageing, and no outcome is guaranteed.
When to Seek Care
- Spreading redness, warmth, pain or discharge at a thread or injection site, or a fever.
- Thread material becoming visible through the skin, or the skin breaking down over it.
- Sudden severe pain after filler, or skin that turns white, dusky or mottled — contact the treating team the same day.
- Any change in vision after an injection on the face — seek emergency care immediately.
- Marked asymmetry, dimpling or bunching that is not settling, for review and possible release or removal.
- Difficulty breathing, or swelling of the lips, tongue or throat — seek emergency care immediately.
