PDO Threads vs Fillers 2026: Which One is Right for You and Your Age

With over 2,000 PDO thread patients treated across her clinics in Nottingham, Birmingham and Leeds, and an equal depth of experience with dermal fillers, Dr. Aguilar has a clear clinical view of who benefits from which treatment, at which age, and why. This is that view.

PDO Threads vs Fillers: The Fundamental Difference You Need to Understand

Threads are usually better for mild to moderate laxity, while fillers are often better for deflation, contour loss, and etched-in lines that stem from reduced facial volume.^[1] This single sentence contains almost everything you need to know to make the right decision, but it requires some unpacking.

PDO threads are biodegradable sutures inserted beneath the skin to physically lift and reposition tissue that has descended with age. They do not add volume. They do not fill anything. Beyond mechanical lifting, PDO threads trigger a controlled healing response. As the body recognises the threads as foreign material, it increases collagen, elastin and hyaluronic acid production around them, gradually enhancing skin firmness, elasticity and texture.^[2]

Dermal fillers are injectable gels, most commonly made from hyaluronic acid, that restore lost volume beneath the skin. They do not lift tissue in the way that threads do. They fill areas that have become hollow, smooth folds that have deepened, and restore the structural support that fat pads provide when they are present. Their results are immediate and highly visible from the first appointment.

This is a perceptive question and the concern about fillers causing puffiness is a legitimate one. The issue, flat and droopy at the same time, is very common in the early to mid forties and is the result of two things happening simultaneously: volume loss in the mid-face fat pads and descent of the soft tissue that used to sit higher. These are two different problems and in many cases they require two different solutions.^[3]

How Facial Ageing Changes What You Actually Need

Understanding why the threads versus fillers question matters so much requires understanding what actually happens to the face as it ages. Ageing is not just one thing. It is several things happening at different rates, in different layers of the face, at different stages of life.

In your late thirties the primary change is often descent, the tissues are moving downward. Volume loss has begun but may not yet be the dominant concern.

In your forties both processes are underway and increasingly visible.

By the fifties, volume loss is often significant, laxity is moderate to marked, and the face may also show changes in skin quality and texture. Each of these stages calls for a different clinical approach.^[4]

PDO Threads vs Fillers by Age: The Honest Clinical Guide

This is not a rigid formula. Individual variation is significant and a consultation with an experienced practitioner is the only way to make a truly personalised recommendation. But the following represents the clinical pattern Dr. Aguilar sees most consistently across her patients in Nottingham, Birmingham and Leeds.

Because threads are the clinically appropriate treatment for jowls. Jowling is a descent problem, not a volume problem. Adding filler to a jowl does not reposition the tissue, it adds volume to descended tissue, which can make the jowl appear more pronounced rather than less. Threads physically lift and reposition the tissue back toward where it originally sat. This is the correct intervention for a descent-driven concern.^[1]

Which Treatment Areas Suit PDO Threads and Which Suit Fillers

Not every area of the face responds equally well to threads and not every area needs volume restoration. Understanding which treatment works best where helps clarify the decision considerably.

Can You Have PDO Threads and Fillers at the Same Time?

Yes, and in many cases the combination produces better results than either treatment alone. Combining the two offers the most natural outcome for many patients, threads reposition skin while fillers soften folds or restore volume.^[3]

The sequencing matters. Dr. Aguilar's clinical preference is generally to place threads first where both are being done in the same session, as this establishes the new tissue position before volume is restored. Placing filler into descended tissue and then repositioning it with threads can occasionally shift the filler to an unintended location.

When done by an experienced practitioner in the right sequence, threads and fillers work synergistically rather than against each other. The threads create the structural lift and the collagen framework. The fillers restore the volume that the repositioned tissue was masking. The result is a face that looks rested, defined and natural rather than one that looks treated. The key is having both done by the same practitioner with a clear clinical plan.^[6]

PDO Threads vs Fillers: Longevity, Cost and What Lasts Longer

Dr. Aguilar recommends that PDO thread patients return at 10 to 12 months for repeat treatment, before the collagen response has fully diminished. At this point the second treatment builds on the biological foundation of the first rather than starting from zero. Over several years of annual treatment, many patients find that their results improve progressively rather than plateauing or declining.

The Combination Approach: What Dr. Gabriela Aguilar Recommends

There is no single answer to the threads versus fillers question because there is no single face and no single pattern of ageing. What Dr. Aguilar offers every patient is a clinical assessment that looks honestly at what the face needs, not what the patient arrived expecting.

In practice, many patients benefit from a thoughtfully planned combination: threads to address descent and restore definition, fillers used conservatively to restore volume where it has genuinely been lost.

The goal is always the same, a face that looks like a better, rested version of itself, not a face that looks like it has been treated.^[6]

PDO Thread and Filler Treatments in Nottingham, Birmingham and Leeds

Dr. Gabriela Aguilar offers both PDO thread lifts and dermal filler treatments at all three of her clinic locations. All consultations are carried out by Dr. Aguilar personally. She will assess your face, discuss your concerns, and give you an honest clinical recommendation, which may be threads, fillers, a combination of both, or a different approach entirely if that is what your skin actually needs.

There is no obligation to proceed and no pressure to choose a treatment before you are ready. Consultations can be booked via cosmeticdoctoruk.com or by contacting the clinic directly.
