PDO Thread Lift vs Dermal Fillers: Which Is Right for Lifting Jowls and Sagging Skin?

Key Takeaways

• PDO threads lift, fillers restore volume: These two treatments work through entirely different mechanisms. Threads physically reposition descended tissue; fillers replace lost volume and provide indirect structural support. Choosing the wrong one for the wrong problem is one of the most common mistakes patients make.
• The cause of your jowls determines which treatment fits: If gravity and skin laxity are the main driver, threads are usually more clinically appropriate. If hollowing in the mid-face is pulling the lower face down, targeted filler placement often delivers a better result.
• Combination treatment is often the most effective approach: For many patients presenting with both tissue descent and volume loss, an experienced clinician will plan threads and filler together as a staged or same-session treatment, each addressing what the other cannot.
• Realistic UK pricing ranges from roughly £600 to £1,500 for jawline threads, and £400 to £800 per area for dermal filler: Both are indicative figures and vary significantly by clinic, practitioner experience, product used, and the number of threads or ml of filler required.
• Medisha Clinic, Mayfair and Marylebone: Dr Nish Shah offers both Intraline PDO thread lifting and advanced dermal filler treatments, providing a genuinely dual-option approach to jowl correction and lower face rejuvenation at its central London locations.

The short answer is that PDO threads and dermal fillers are not competing treatments doing the same job; they work differently, suit different presentations, and produce different results. PDO threads mechanically lift and reposition tissue that gravity has moved; dermal fillers restore the volume that ageing has taken away. Understanding which problem you are actually dealing with is the starting point for every good treatment plan.

How Each Treatment Works: The Mechanism Behind the Lift

Before comparing the two side by side, it helps to understand what each treatment is actually doing beneath the skin. They are fundamentally different interventions, and that distinction shapes everything about which one suits your situation.

• PDO thread insertion: A thread lift for jowls involves placing absorbable threads beneath the skin to support and subtly reposition selected tissue in the lower face. PDO stands for polydioxanone, a synthetic material used in absorbable medical sutures, and the threads gradually break down after placement. The threads carry tiny barbs, cogs, or cones that grip the tissue and provide an immediate mechanical lift. As the threads dissolve over the following months, they stimulate collagen production around the thread pathway, which provides an ongoing tightening effect after the thread itself has been absorbed.
• Cog threads versus mono threads: Not all PDO threads perform the same role. The immediate lifting effect on the jawline, the mid-face, and the jowl comes from cog threads placed at the appropriate depth and direction for the area being treated. Twisted or spiralled threads, by contrast, provide volumetric support in the subcutaneous tissue and are most commonly used in areas of volume deficit, such as the temples and cheeks, where the goal is to restore subtle three-dimensionality alongside collagen stimulation.
• The collagen-building phase: A 2025 study published in the Journal of Cosmetic Dermatology confirmed collagen formation around PDO threads through ultrasound imaging in all ten patients studied, alongside measurable improvement in skin sagging. The threads themselves dissolve through hydrolysis within four to six months, but the collagen framework they triggered stays in place, and that is what gives results their staying power.
• How dermal fillers address jowls: Fillers work from a completely different starting point. Dermal fillers work by reinstating volume in areas which have lost fat and structure. Restoring volume in key areas helps to lift the skin upwards, away from the chin area, reducing the severity of jowls and helping to sculpt the jawline. This is an indirect lift, not a mechanical one. The filler acts as a scaffold that supports sagging tissue from below, rather than pulling it upward from within.
• The top-down filler approach: When targeting jowls specifically, it is important to assess the whole face rather than just the chin area. A considered approach involves building the scaffolding higher up in the face by placing fillers around the temples and cheeks, helping to add plumpness in these regions. This increased volume higher up helps to lift sagging skin from near the jawline area, allowing this region to become more sculpted and firmer.
• The pre-jowl sulcus: One specific anatomical target that filler addresses particularly well is the pre-jowl sulcus. This small dip in front of the chin often causes the jawline to look interrupted or saggy, and by filling this area a clinician can create a continuous, smooth transition from the chin to the ear. Threads alone will not correct this specific hollow.
• Collagen-stimulating filler options: In addition to standard hyaluronic acid fillers, regenerative products like Ellansé promote the body’s natural collagen production, offering both immediate improvement and long-term skin health benefits, making them suitable for clients seeking lasting results.

Results, Longevity, Downtime, and Cost: What to Realistically Expect

The comparison on paper looks fairly clean, but the reality is a little more nuanced when you factor in recovery, how long the results last, and what you are likely to spend. Here is what the evidence and current UK market data suggest.

• PDO thread results timeline: Immediately after treatment, there is visible lift alongside some swelling, tightness, and occasionally dimpling. Within one to two weeks, swelling settles and dimpling smooths out. At two to three months, collagen production peaks and skin feels firmer and looks more elastic. From twelve to twenty-four months, the lift slowly softens as the collagen scaffold ages, but many patients still look fresher than they did before treatment.
• PDO thread longevity: The results of a thread lift typically last twelve to twenty-four months depending on the thread type used. PDO threads generally last twelve to eighteen months, while PLLA and PCL threads may provide results lasting eighteen to twenty-four months.
• PDO thread lift recovery: There is a recovery time involved with swelling of treated areas, discomfort, difficulty opening the mouth widely for the first couple of weeks after treatment, as well as potential temporary asymmetry, bruising, protrusion of threads, and dimpling. Most people feel ready for normal daily tasks within five to seven days. This makes thread lifts a notably longer recovery than dermal filler, which is worth factoring in when planning around social or professional commitments.
• Dermal filler recovery: Filler is typically the quicker recovery of the two. If you want a minimally invasive treatment that allows you to return to normal activities almost immediately, a non-surgical jowl lift using filler may be the better option, with minimal after-effects such as mild redness or bruising, so most patients can return to work the very next day.
• PDO thread lift costs in the UK: Thread lifts in the UK typically cost £600 to £2,000 per treatment area in 2026. Mid-face threads run £800 to £2,000, jawline treatments £600 to £1,500, and neck treatments £700 to £1,800. Combined treatments cost £1,200 to £3,500. These are indicative figures and vary by clinic, thread type, and the number of threads required for your anatomy.
• Dermal filler costs in the UK: Dermal fillers in the UK usually cost £200 to £600 per syringe. Cheek or jawline fillers tend to run higher, from £400 to £800 per area. Premium filler lines that use advanced cross-linking technology and last longer command an extra £50 to £120 per syringe. A full lower-face jowl correction using filler often requires multiple syringes across several areas, so the total investment can be comparable to threads when you factor in the volume needed.
• Reversibility: Hyaluronic acid dermal fillers can be dissolved with hyaluronidase if the result does not suit the patient, which provides a safety net threads cannot match. PDO threads cannot be reversed once placed, though they will naturally dissolve over time. This is a meaningful clinical difference when deciding between the two, and worth discussing at consultation.

Who Is Each Treatment Best Suited For?

Neither treatment is universally superior. The correct choice depends almost entirely on the anatomy in front of the clinician, and a good consultation should address this clearly rather than defaulting to whichever the clinic happens to favour.

• PDO thread lift candidates: PDO thread lifts work best for adults with mild to moderate skin laxity. Patients in their late thirties through fifties often see the most benefit, particularly those who have noticed jowls, loose skin around the jawline, or a loss of definition in the mid-face. They are best suited to younger patients with smaller jowls where there is enough skin elasticity to hold the repositioned tissue without bunching.
• Dermal filler candidates: Dermal fillers are designed to correct volume loss, sculpt cheeks or lips, smooth nasolabial folds, enhance the jawline, or treat under-eye hollows. A patient whose primary issue is the face looking hollowed or deflated in the mid-zone will respond better to filler than to threads. If gravity has caused sagging skin but volume remains, threads may be the answer. If hollowness or flattened features are the issue, fillers are ideal.
• Patients who are not ideal candidates for threads: A PDO thread lift may create a subtle improvement in mild to moderate jowls by supporting and repositioning selected lower-face tissue. It cannot remove a large amount of loose skin, eliminate significant fat beneath the chin, or reproduce the result of a surgical facelift. Patients with significant excess skin, very heavy jowls, or advanced laxity are likely to be disappointed by threads and should be counselled honestly about surgical options.
• Patients who are not ideal candidates for filler alone: Fillers help a little by filling underneath and sometimes buttressing sagging areas with mild lift through internal support. But fillers alone are rarely sufficient when laxity is moderate to severe. Adding more volume to a face that has descended can sometimes make the problem look worse rather than better, which is the concern Mumsnet users and aesthetics forums frequently raise. The risk of an overfilled, heavy appearance is real when filler is used as a substitute for a lift rather than as a complement to one.
• Lifestyle considerations: The downtime difference is a genuine factor. Someone with a demanding social calendar or professional commitments involving public-facing work may find that threads require a longer window to plan around, while filler is far more forgiving in this respect.

Four Questions That Come Up Every Time: Myths, Mumsnet, Combinations, and Maintenance

“Can filler actually lift, or does it just fill?”

This is the debate that runs through every Mumsnet aesthetics thread on the subject, and the honest answer is: both, to a limited extent. Threads correct sagging, while fillers correct volume loss. But the division is not absolute. Strategic filler placement in the cheeks and along the mandible does create a degree of mechanical stretch and indirect lift. Increased volume higher up helps to lift sagging skin from near the jawline area, allowing this region to become more sculpted and firmer. The problem is that fillers can indirectly improve mild sagging by restoring lost mid-face volume, but they cannot physically reposition tissues that have descended due to gravity. So filler can appear to lift when the underlying issue is volume loss, but it cannot do what a thread does when true tissue descent is the problem.

What about combining both treatments?

In many cases, a combined treatment approach utilising a thread lift, dermal fillers, energy-based devices, skin boosters, or polynucleotides is more effective than any standalone treatment. This is not just a commercial argument; it reflects the clinical reality that ageing is multi-factorial. PDO threads are rarely the complete answer on their own, because laxity rarely exists in isolation from the other drivers of facial ageing. Most patients presenting with jowling or mid-face descent also have some degree of volume loss, skin quality decline, or both. The physical lift achieved with threads can help to reposition tissue and provide a good foundation to add dermal filler only in the necessary areas where additional volume is desired. Then, as the filler dissolves over time, the collagen produced from the PDO threads continues to support and provide volume after the suture has been absorbed by the body, resulting in a nuanced transformation that combines the volume-enhancing properties of fillers with the lift and collagen-induced improvements of PDO. Some clinicians place threads first, then fillers after a few weeks once the swelling has settled, which allows a more accurate assessment of the remaining volume deficit.

Common myths worth addressing

A few misconceptions circulate regularly, both online and in clinic waiting rooms. The first is that threads are a direct replacement for a facelift. They are not. A PDO thread lift is a cheaper and faster alternative to facelift surgery, but the results do not last as long and are not as dramatic. The second is that filler always makes jowls look worse. That is not categorically true either; filler placed by a skilled clinician in the right anatomical locations can meaningfully reduce the appearance of early jowling. Many patients worry about using fillers because they do not want to make their face look heavy, but the goal is to restore areas of volume loss back to how they were before that volume was lost, rather than to simply inflate the whole face, and that comes down to the technical expertise of the clinician. The third myth is that threads are always the more natural option. Minor complications occur in fifteen to twenty per cent of PDO thread procedures and can include temporary dimpling, thread visibility, or asymmetry, all of which require an experienced hand to minimise.

How do you maintain results over time?

Neither treatment is permanent, and maintenance planning is part of any honest treatment conversation. Threads stimulate collagen over three to four months, with most people enjoying a firmer, lifted look for nine to fifteen months depending on skin quality and lifestyle. Planning a review around twelve months allows some patients to combine follow-up therapy with skin boosters or device-based collagen work to maintain definition and skin quality. For filler, the maintenance interval depends on the product used and the area treated. Results typically last twelve to eighteen months for structural filler placed in low-movement areas such as the cheeks and jawline. Some patients find that a combination approach, where threads and filler are staggered and maintained alternately, means they are rarely starting from scratch, which can reduce the cumulative cost over several years compared to repeating either treatment in isolation.

Whether your assessment points to threads, filler, or a carefully sequenced combination of both, the Medisha team’s dual-option capability and Mayfair and Marylebone locations mean you receive genuinely personalised advice without pressure towards a single treatment pathway.

Frequently Asked Questions

How do I know whether I need a PDO thread lift or filler for my jowls?

The honest answer is that you may not be able to tell without a clinical assessment, because the cause of jowling varies from person to person. A simple test that many clinicians use is to place their fingertips gently on the cheeks and lift. This is not a guarantee of the finished result, but it helps establish whether a thread lift is likely to create enough improvement to justify treatment. If lifting the mid-face significantly improves the jowl, volume restoration via filler in the cheeks may be effective. If the tissue feels heavy and descended with good underlying volume, threads are more likely to address the root cause. The choice often comes down to the patient’s primary concern: if the issue is sagging or skin laxity, threads provide better results; if the face looks deflated or hollow, fillers are usually the more appropriate answer. A consultation with a clinician who offers both treatments is the most reliable way to get an impartial answer.

Will a PDO thread lift hurt?

Topical anaesthetic cream is applied before the procedure, and local anaesthetic is typically infiltrated into the entry points, so most patients experience only mild pressure or a pulling sensation during treatment rather than sharp pain. Mild discomfort is expected after a thread lift, but persistent pain, tenderness, or difficulty moving facial muscles, particularly opening the mouth, may indicate that threads have been placed incorrectly, too deeply, or near a sensitive area, and warrants medical review. In the immediate days after treatment, tightness and some discomfort when chewing or opening the mouth widely is normal as the threads settle. Days four to five tend to feel easier as talking and smiling feel less restricted and any dimpling begins to smooth. Following aftercare instructions carefully makes a meaningful difference to how comfortable the recovery feels.

Can I have filler and PDO threads at the same time?

A patient with saggy cheeks and hollow under-eyes might receive threads to lift the cheek plane and jowls, and then hyaluronic acid filler in the tear troughs and mid-face to restore contour. Careful timing is crucial; some clinicians place threads first, then fillers after a few weeks once the swelling has settled. When planning a combined approach, it is important to respect tissue planes, avoid overcorrection, and select safe dosing. Whether both are performed in the same session or staged depends on the treating clinician’s assessment of your anatomy and the degree of correction needed. Book a consultation to discuss the approach that suits your specific situation.

How long do PDO thread results last compared to filler?

Threads last twelve to eighteen months; fillers last six to twenty-four months depending on the product. In practice, structural fillers placed in the cheeks and jawline tend to sit at the longer end of that range because these are relatively low-movement areas. Threads are absorbed by the body through hydrolysis, but peak collagen stimulation happens around months two to three, meaning the benefit you experience is not just from the physical thread itself but from the new collagen your body lays down around it. Some patients find that repeat treatments yield progressively better results due to accumulated collagen, which is worth factoring into long-term treatment planning.

What are the key risks I should know about before having PDO threads?

PDO thread lifts have a much lower risk of complications than facelift surgeries, with less risk of scarring, severe bruising, or bleeding when performed by a trained professional. Minor complications occur in fifteen to twenty per cent of procedures but are usually easily corrected. The more common issues include temporary bruising, dimpling, a feeling of tightness, and occasionally a thread becoming visible or palpable beneath the skin, particularly in patients with thinner skin. If threads are inserted at the wrong depth, there is a risk of damaging nerves, which can lead to numbness, tingling, or muscle weakness, though serious complications of this kind are rare when treatment is carried out by a qualified clinician with sound anatomical knowledge. The thread lift is regulated by the CQC in England, with a requirement for medical assessment before treatment and established clinical protocols including infection control and minor surgery protocols.

Do dermal fillers in the cheeks really help with jowls, or is that a myth?

It is not a myth, though the degree of improvement depends heavily on what is driving the jowling. Building the scaffolding higher up in the face by placing fillers around the temples and cheeks helps to add plumpness in these regions, and this increased volume higher up helps to lift sagging skin from near the jawline area. The principle is sound: restoring the projection lost from the cheek fat pads reduces the downward pull on the lower face. Where it is less effective is when significant tissue descent has already occurred; in those cases, cheek filler alone may not produce enough visible change to justify the intervention without threads or other lifting modalities. A dermal filler facelift using cheek filler is highly effective in mild cases of sagging jowls, and your clinician’s honest assessment of severity is the critical factor in setting realistic expectations.

What should I avoid before and after a thread lift?

It is recommended to avoid alcohol, smoking, and blood-thinning medications in the days leading up to your appointment, since these can increase the risk of bruising or slow healing. After treatment, it is advisable to avoid strenuous activities and vigorous facial movements to prevent aggravating the treated zones. You should also keep follow-up appointments and avoid dental appointments for two weeks, since opening the mouth wide repeatedly can displace the threads before they have anchored properly. Sleeping on your back with your head slightly elevated in the first few nights helps manage swelling and reduces the risk of thread migration. Your clinician will provide written aftercare instructions tailored to the specific technique used.

Could Profhilo or skin boosters be an alternative to either treatment for jowls?

Profhilo and other skin boosters work through a different mechanism again. They are injectable hyaluronic acid treatments that spread through the tissue to improve hydration, skin laxity, and overall skin quality, rather than delivering structural volume like a traditional filler or providing a mechanical lift like threads. They are an effective adjunct for improving skin texture and mild laxity, and Profhilo is a treatment that can help with the appearance of mild sagging jowls. However, for moderate or more established jowling, a skin booster is unlikely to be sufficient as a standalone treatment and is more commonly used alongside threads or filler as part of a broader programme. Think of it as improving the quality of the envelope rather than repositioning its contents.

Is there an age at which threads stop being suitable?

The ideal candidate for a thread lift has strong bony projections with skin thick enough so that the suture and cones are not palpable beneath the surface. As skin thins with age and laxity becomes more significant, the risk of visible threads and the degree of achievable lift both change. For advanced sagging, a surgical facelift offers more dramatic, longer-lasting correction, and it would be misleading to suggest otherwise. Most experienced clinicians in the UK will tell you that threads work best from the late thirties through the mid-fifties, with individual anatomy playing a bigger role than age alone. A patient in their early sixties with excellent skin quality and mild laxity may still be a good candidate; a patient in their late forties with heavily descended tissue may not be. The consultation is where this is properly assessed.
