A thread lift can provide a modest, temporary change in facial contour for selected patients. How long that change remains noticeable depends on the thread system, the treated area and the tissue being supported. There is no reliable duration that applies to every treatment, and a two-year result should not be taken as a guarantee.
The decision also involves recovery and risk. Bruising, swelling and tenderness can occur, while complications include persistent dimpling, asymmetry, infection and visible or exposed threads. Understanding what the procedure can realistically achieve is as important as understanding how it is performed.
What does a thread lift actually do?
Thread treatments place medical sutures beneath the skin. Depending on their design, they may support or reposition suitable tissue, or aim to improve skin firmness gradually. Treatment generally involves marking the planned areas, disinfecting the skin and using local anaesthesia before placing the threads.
Threads do not remove a substantial amount of excess skin. If your main concern is pronounced sagging or a change that requires surgical repositioning, a thread-based treatment may not deliver the result you want. A consultation should establish the cause of the concern before choosing a procedure.
Smooth threads and lifting threads have different roles
Thread options include PDO mono, COG, APTOS and Silhouette Soft systems. PDO mono threads are smooth, absorbable polydioxanone threads intended for gradual changes in skin structure and firmness. They should not be expected to produce the same mechanical lift as threads that grip tissue.
COG threads have barbs that provide tissue hold. Silhouette Soft uses cones, while APTOS includes different systems selected for the treatment plan. A name alone does not tell you everything about the thread’s composition, placement or expected result. Ask which specific system is proposed and what it is intended to change.
How long does a thread lift last?
There is no single evidence-based duration for all thread lifts. How long the material remains in the tissue, how long a visible lift lasts and how the skin responds are different questions. Ask for an estimate specific to the proposed thread system and treatment area.
An updated systematic review published in 2025 included 12 studies involving 818 patients. It found improvements in immediate outcome scores, but identified a shortage of evidence on long-term effectiveness. The longest follow-up was two years; that does not mean every participant maintained a meaningful lift for two years.
When you are given a duration estimate, ask what it refers to. Is it the persistence of the thread material, a measurable lifting effect, improved skin firmness or patient satisfaction? Those outcomes cannot be used interchangeably.
Why the result may differ between patients
Skin thickness, tissue weight, the amount of laxity and previous treatments all influence planning. The clinician also needs to consider whether the proposed threads can support the area in a useful way. A result in the cheek should not automatically be used to predict a result around the brow.
Agree on the change you want to see and how it will be assessed. Photographs taken under consistent lighting and with the same facial expression can make the review more useful.
When will you be able to judge the result?
A treatment designed to reposition tissue may produce an early visible change. Swelling and tissue settling can then alter the appearance over the following weeks. Smooth threads aimed at gradual skin changes have a different course.
Gradual changes after PDO mono treatment may be assessed over approximately six to twelve weeks. With Silhouette Soft, a review over two to three months can help assess the developing result. These are assessment periods, not predictions of how long swelling will last or promises that the result will remain unchanged afterwards.
Agree on an early contact plan and a later review before treatment. You should know when to report a concern and when the clinic expects to evaluate the cosmetic outcome. A review does not automatically mean more threads should be inserted.
What are the risks of a thread lift?
Early reactions and recovery
Bruising, swelling, tenderness and temporary skin indentations may occur. Some people also experience tightness or difficulty opening the mouth comfortably. These effects can interfere with work, social plans or eating even when no major complication has occurred.
Visible recovery after PDO mono or Silhouette Soft treatment may take around three to seven days, although swelling or bruising can last longer. Restrictions on exercise or facial movement may continue after visible marks improve. Confirm the plan for your specific thread system.
Complications that may need treatment
Potential complications include persistent contour irregularities, unwanted asymmetry, infection, altered sensation and threads that can be seen or felt. A thread may also become exposed through the skin. Nerve irritation and persistent pain are additional concerns.
A 2021 meta-analysis of 26 studies estimated swelling at 35%, dimpling at 10% and infection at 2%. These pooled figures came from different studies and techniques and cannot predict your personal risk. They also combine early reactions with problems that have different clinical significance.
Some complications require correction or thread removal. Removal should not be presented as a simple, guaranteed reversal: the approach depends on the thread, its position, healing and the problem being treated.
When to contact the clinic
Contact the treating clinic promptly if you develop increasing redness or warmth, discharge, fever, worsening pain, marked asymmetry or a visible thread. New weakness or a significant change in sensation also deserves medical assessment.
Do not pull, cut or push an exposed thread back under the skin. Avoid massaging a dimple or irregular area unless the treating clinician has specifically advised you to do so. If symptoms are severe or rapidly worsening and the clinic is unavailable, seek urgent medical care.
Who may be suitable, and when should you consider alternatives?
Thread treatment is generally considered for selected concerns involving mild laxity or tissue descent. Suitability depends on more than age. The clinician should assess skin quality, tissue thickness and weight, facial movement, medical history and previous procedures.
If there is substantial excess skin or you want a stronger, more durable repositioning, discuss whether a surgical opinion would be more appropriate. If the concern is primarily volume loss or surface texture, ask whether a different type of treatment better addresses it. Choosing a procedure starts with identifying the problem.
You should also feel comfortable choosing no treatment. A small expected improvement may not be worth the recovery, expense or possibility of correction for every person.
How to prepare and what aftercare involves
Before treatment, tell the clinician about previous threads, facial procedures, blood-thinning medicines, bleeding problems, skin infections, scarring tendencies and planned dental work. Do not stop prescribed medicines independently. An active infection or significant inflammation may mean postponing the procedure.
Keep the treated area clean and avoid massage, pulling or pressure to test the threads. Depending on the technique, your aftercare plan may include avoiding strenuous activity, sauna, strong heat and aggressive facial treatments for one to two weeks. You may also be advised to reduce forceful chewing and very wide mouth opening during early recovery.
Follow the personal instructions supplied for your treatment. Ask for clear advice about sleeping position, exercise, dental appointments and other facial procedures. Written before and aftercare guidance can help you remember the instructions, but it should be used alongside your individual plan.
Questions to ask before deciding
A useful consultation should leave you able to answer the following:
- Which thread system will be used, and is the goal tissue lifting or gradual improvement in skin firmness?
- What change is realistic for my anatomy, and what are the alternatives?
- What supports the proposed duration estimate for this treatment area?
- How many threads and treatment areas are included in the written quote?
- When will the result be reviewed, and whom should I contact about a problem?
- How would persistent dimpling, visible threads or asymmetry be managed, and what costs could arise?
Ask for a written quote that identifies the thread system, number of threads, treated areas and follow-up arrangements. Clarify any costs for assessing or correcting an unwanted result.
Frequently asked questions
Do all thread lifts last two years?
No. That is not a dependable expectation for every system, treatment area or patient. Ask for a realistic estimate for the procedure being proposed and an explanation of the uncertainty.
Does dissolving mean the result disappears immediately?
Thread absorption and visible cosmetic benefit do not follow an identical timetable. Nor does a proposed collagen response prove that a lifting effect will persist for a particular number of months.
Is dimpling always a complication?
An indentation can occur early after treatment, but persistent, pronounced or worsening dimpling needs assessment. The treating clinician should explain which changes are expected and when to arrange a review.
Can I have a thread lift shortly before an important event?
Allow time for visible recovery and review rather than relying on an immediate settled result. Discuss the event date before booking; bruising, swelling or an irregular contour may last longer than expected.
Deciding whether a thread lift suits your goals
Different thread lift treatments serve different purposes. An individual consultation should clarify whether threads suit your concern, which system is proposed and what recovery and follow-up involve. A sound decision rests on a realistic expected benefit and a clear plan for handling problems.
