If you are thinking about having a thread lift in Manchester, one of the most common questions is how long the threads stay in the skin and when they dissolve. PDO threads are an increasingly popular non-surgical alternative to a facelift. They work by lifting the skin and stimulating collagen, but because they are made of dissolvable material, many patients want to know exactly what happens to them and how long they last.
We explain what PDO threads are, how they dissolve, how long results last, the factors that influence longevity, and what you can expect at every stage of the process. We also answer some frequently asked questions and compare PDO with other thread types used in aesthetics.
What Are PDO Threads?
PDO stands for polydioxanone, a medical-grade, biodegradable material that has been used safely in surgery for decades. It is most familiar as the material used for dissolvable stitches. In aesthetic medicine, PDO threads are fine sutures that are carefully placed under the skin to provide a lifting effect, improve definition, and stimulate the body to make new collagen.
There are different types of PDO threads available, and each one serves a slightly different purpose. Mono threads are smooth and are usually used for skin tightening and improving texture. Screw or tornado threads are coiled and help add a touch of volume. Barbed or cog threads have tiny hooks that anchor into the tissue and provide an immediate lifting effect, which is most commonly used for jawline or cheek lifting.
At CLNQ, we select the type of thread and placement pattern based on each patient’s anatomy and goals. This ensures results that look natural and are tailored to the individual.
How Do PDO Threads Dissolve?
PDO threads dissolve through a process called hydrolysis. This means that the natural water content in your tissues slowly breaks down the material into smaller fragments until it becomes water and carbon dioxide, which the body then clears away safely.
You will not feel this process happening. The threads do not “disappear suddenly” but are gradually absorbed over a period of months. During this time, they also stimulate the production of collagen, elastin, and hyaluronic acid in the skin, which is why results often outlast the presence of the threads themselves.
How Long Do PDO Threads Last?
On average, PDO threads dissolve within six to nine months. The visible lifting and tightening effect can last much longer, often between twelve and eighteen months. This is because even after the threads have gone, the collagen they triggered remains in place, acting as a natural support structure.
Some patients enjoy their results for up to two years, especially if they combine their thread lift with good skincare, sun protection, and maintenance treatments.
What Affects How Quickly PDO Threads Dissolve?
There are several factors that can influence how long PDO threads take to dissolve and how long the results last:
-
Type of thread used: Thicker barbed threads tend to last longer than fine mono threads.
-
Number and placement: More threads and strategic vector placement can provide stronger and longer-lasting support.
-
Your metabolism: People with faster metabolisms may break down the threads more quickly.
-
Skin quality and age: Younger patients or those with better skin elasticity tend to get longer-lasting results.
-
Lifestyle: Smoking, heavy sun exposure, and poor sleep can all shorten results. On the other hand, good skincare, sun protection, and a healthy lifestyle help maintain them.
-
Aftercare: Following aftercare instructions, such as avoiding excessive facial movement, heat, and pressure on the face during the early healing period, allows the threads to settle properly and last longer.
PDO vs PLLA vs PCL Threads
PDO threads are not the only type of dissolvable threads used in aesthetics. Two other common options are PLLA (poly-L-lactic acid) and PCL (polycaprolactone).
-
PDO threads dissolve in about 6–9 months, with results lasting 12–18 months.
-
PLLA threads dissolve in 12–18 months, with results often lasting up to 24 months.
-
PCL threads take the longest to dissolve, often 18–24 months or more, with results lasting up to 36 months.
Each type has its advantages, and the choice depends on your goals, age, and skin quality. PDO threads are extremely safe, predictable, and effective for patients looking for a natural refresh with minimal downtime.
Timeline of PDO Thread Dissolution and Results
To understand what happens after a thread lift, here is a typical timeline:
Day 0–3: You may feel tightness and experience mild swelling or bruising. Any dimpling at the skin entry points usually smooths out on its own.
Week 1–2: Discomfort reduces, swelling settles, and you start to feel more comfortable.
Week 3–6: The body begins to produce new collagen around the threads, which enhances the lifting effect and skin quality.
Month 3–6: You reach the peak period where both the threads and the new collagen are working together for the best results.
Month 6–9: Most PDO threads dissolve during this stage. The lift is now maintained by your own collagen framework.
Month 12–18: Results gradually soften as collagen naturally remodels. Many patients choose to refresh their results with a top-up treatment.
Can PDO Threads Be Removed Early?
Unlike dermal fillers, which can be dissolved with hyaluronidase, PDO threads do not have a simple injection that makes them disappear. In the rare case that a thread causes an issue, it may be trimmed, adjusted, or in some situations removed by a skilled practitioner. Fortunately, this is not often necessary when the procedure is done correctly.
Are PDO Threads Safe?
PDO threads have an excellent safety record when performed by trained professionals. Common temporary side effects include swelling, bruising, tenderness, and mild puckering of the skin. These usually resolve within a few days to weeks.
More serious risks, such as infection, asymmetry, or visible threads, are uncommon but should always be discussed during consultation. Choosing an experienced clinic such as CLNQ in Manchester reduces these risks significantly.
Aftercare for PDO Threads
To help your threads settle and last as long as possible, follow these aftercare tips:
-
Sleep on your back with your head elevated for the first week.
-
Avoid vigorous chewing, big yawns, and dental work in the early healing period.
-
Do not rub or massage the face unless advised.
-
Avoid heat, saunas, and steam rooms for at least a week.
-
Use SPF 30–50 daily to protect collagen.
-
Maintain good skincare with antioxidants and retinoids if recommended.
Who Is a Good Candidate?
PDO thread lifts are best for men and women with mild to moderate sagging who want to avoid or delay surgery. They work well for early jowls, mid-face descent, loss of cheek definition, nasolabial folds, marionette lines, jawline softening, or light neck laxity.
Patients with more advanced skin laxity may need a surgical facelift for optimal results. At CLNQ, we provide honest advice and can recommend the most suitable options, whether that is PDO threads, alternative thread types, injectables, or facelift surgery.

Will I feel the threads dissolving?
No, the process is gradual and not something you can feel.
Can PDO threads be dissolved quickly if I don’t like them?
No, there is no injection to dissolve them. Any issues usually settle with time, but threads can be trimmed or removed if necessary.

How much downtime is there?
Most patients resume normal activities within two to three days, with any bruising easily covered by makeup.
Who should avoid PDO threads?
They are not suitable if you are pregnant, breastfeeding, or have certain health conditions affecting healing. Your clinician will review your medical history before treatment.
Final Thoughts
