PDO Threads vs Filler: Lifting vs Volumising

PDO threads and dermal filler are often mentioned together, but they work in opposite ways. Threads mechanically reposition tissue that has started to sag, while hyaluronic acid filler adds volume where it has been lost. The right choice depends on whether your main concern is descent, deflation, or a bit of both.

Telling those two apart is not always easy when you are looking in the mirror. This guide walks through how each treatment works and how a clinician decides between them.

Sagging and volume loss are different problems

As the face ages, several changes happen together. Fat pads in the cheeks shrink and shift downward. Bone in the jaw and around the eyes gradually changes shape. The ligaments that hold tissue in place loosen, and skin loses collagen and elasticity.

The result can look similar on the surface, a softer jawline or deeper folds, but the cause varies. If the main issue is that tissue has moved down, lifting may help. If the main issue is that tissue has thinned out, adding volume may help. Many people have some of each.

One practical clue: gently lift the skin near your cheekbones with your fingertips while looking in a mirror. If the change you are bothered by mostly improves, descent may be playing a large role. If the area still looks hollow, volume loss is likely a factor too. This is only a rough guide, not a substitute for an in-person assessment.

How each treatment works

PDO threads are fine dissolvable threads placed under the skin with a thin needle or cannula. Barbed threads grip tissue so it can be gently repositioned upward, and all threads trigger a mild healing response that may support new collagen. The threads dissolve over several months. For more detail, see PDO thread lift explained.

Hyaluronic acid filler is a gel injected at different depths to replace lost volume, support structures such as the cheeks or chin, and soften folds. Results are visible right away, with final shape clear once swelling settles. Our article What Are Hyaluronic Acid Dermal Fillers? explains the different product types.

Side-by-side comparison

• Main effect: threads lift and support skin quality; filler restores volume and contour.
• Typical areas: threads are often used along the jawline, jowls, midface, brow and neck; filler in the cheeks, lips, chin, jawline, temples and folds.
• Onset: threads give some immediate lift that settles, with collagen effects developing over months; filler gives a visible change right away.
• Duration: threads often show benefit for around six to twelve months; filler commonly lasts six months to two years depending on the area.
• Reversibility: hyaluronic acid filler can be dissolved with an enzyme; threads dissolve on their own and can sometimes be removed if a problem arises early.
• Recovery: threads often involve more tenderness and a few weeks of activity limits; filler typically involves a few days of swelling and possible bruising.

When threads may make more sense

Threads may be considered for someone whose face still has reasonable volume but has early sagging along the jawline or mild jowling. Adding filler to a face that does not need volume can make it look heavy. In these cases a small, well-planned thread lift may offer a subtler correction.

Threads are not well suited to significant skin excess. If there is a lot of loose skin, neither threads nor filler will give a satisfying result, and a surgical consultation is often the more honest recommendation.

Recovery also matters. Threads usually involve more tenderness and a few weeks of avoiding wide mouth opening and facial massage, so they may not suit someone who cannot take that time.

When filler may make more sense

Filler is often a better first step when hollowness is the main issue, such as flattened cheeks, a recessed chin or temple hollowing. Restoring support in the midface can also soften folds lower down, because the tissue is better held up from above. Filler may also suit people who prefer a lower-recovery option, or who want the reassurance of reversibility.

When both make sense

For some people, the most natural approach uses both treatments, often staged over time. A common sequence is to restore key areas of volume first, then reassess whether lifting is still needed. Starting with support can reduce the number of threads required, or show that threads are not needed at all.

Combining treatments increases the overall risk and cost, so each step should have a clear purpose. A good plan also leaves room to stop at any stage if you are happy with the result.

Risks and who should avoid each

Both treatments are generally postponed during pregnancy and breastfeeding, and when there is active infection, a cold sore or inflamed skin in the area. People with autoimmune conditions, bleeding disorders or a tendency to keloid scarring need careful individual review.

Threads can cause swelling, bruising, tenderness, dimpling, visible or palpable threads, and infection. Filler can cause swelling, bruising, lumps, asymmetry and, rarely, vascular occlusion, which needs urgent treatment. Tell your physician about all medications; do not stop prescribed blood thinners without guidance from the doctor who prescribed them.

Frequently asked questions

Can threads and filler be done on the same day?

It is possible in some cases, but many clinicians prefer to stage them a few weeks apart. This allows swelling to settle and makes it easier to judge what each treatment has achieved.

Which looks more natural?

Neither is automatically more natural. A result looks natural when the treatment matches the cause and is done in moderation.

Can I have threads if I already have filler?

Often, yes, but your clinician needs to know where and when the filler was placed. Threads are usually avoided where permanent fillers or implants are present.

Choosing your approach

The key question is not "threads or filler?" but "what is actually changing in my face?" Answering that well takes a careful assessment. If you would like an opinion on whether lifting, volume, both or neither would suit you, a consultation with HealthPark Medical Aesthetics is a chance to talk it through without pressure to proceed.
