In short. Filler candidacy is the assessment of whether the problem you have matches what filler can do, in a face that can safely receive it. It checks volume zone by zone, contour, tissue support, skin health, medical history and expectation, and a candid assessment sometimes ends with the recommendation that filler is the wrong treatment.
Key points
- Candidacy is not a score you pass; it asks whether filler matches the problem.
- Volume loss is not uniform, so the face is assessed zone by zone.
- Contour changes are less forgiving than volume changes, so a conservative first plan matters.
- Descended tissue needs a different treatment, because filler will not lift it.
- A candid assessment can end with no treatment and a named next step.
What is a filler assessment deciding?
Candidacy for filler is not a score you pass. It is the answer to one question: does the problem you have match what filler can do, in a face that can safely receive it? The assessment usually takes longer than patients expect, and the most useful part of it is often the finding that filler is not the answer.
Volume is assessed zone by zone
The face is assessed zone by zone rather than as a whole, because volume loss is not uniform. Temples, mid-face, tear trough and jaw hollows change at different rates, and the pattern is different in every face. Treating the wrong zone produces a change nobody asked for; treating all of them produces a face that reads fuller but not necessarily better.
Contour is less forgiving than volume
Definition along the jawline, chin and cheekbones is assessed separately from volume. Contour changes are less forgiving: because they are visible against a background of shadow, adding a millimetre too much is noticeable in a way that a millimetre of volume is not. This is one of the reasons a conservative first plan matters more for contour than for volume.
Support and laxity decide whether filler helps at all
Tissue support is assessed by looking at how the face behaves in movement and at rest, not only at how full it is. Where tissue has descended, the honest finding is that filler will not lift it and may make it read heavier. Where skin is lax, a tightening treatment is the relevant option. Where the underlying bone or bite is the problem, filler in front of it does not change the relationship.
What makes the skin unsuitable on the day?
Active infection, inflammation, broken skin or an active acne flare over the intended site are reasons to wait. So is significant skin disease that has not been diagnosed. Filler introduces material into tissue, and the tissue it enters should be healthy first.
Which history changes the plan?
Previous filler, including products whose identity is unknown; any previous delayed reaction, nodule or infection; autoimmune and inflammatory conditions; medication affecting clotting; pregnancy and breastfeeding; and any history of poor scarring are all recorded. None of these automatically excludes treatment, but each changes the plan, the class chosen, or the decision to treat at all.
Motivation and expectation
Finally, the assessment asks what you want and why now. A patient who can describe how they want their face to read, and who accepts that other people may notice nothing, tends to be satisfied. A patient who wants a specific feature matched to a photograph usually is not, whatever the technical result.
How the findings change the decision
| Finding | What the assessment records | What it means for filler | What it means for the plan |
|---|---|---|---|
| Volume loss in the temples, mid-face, tear trough or jaw | Which zones have changed | Filler can restore volume there | Treat the zone that changed, not all of them |
| Loss of definition along the jawline, chin or cheekbones | Contour rather than volume | A small addition is noticeable | A conservative first plan |
| Descended tissue or lax skin | Support, not volume | Filler will not lift it | A tightening treatment or a surgical opinion |
| Active infection, inflammation or broken skin at the site | Skin health | Treatment waits | Reassess when the skin is healthy |
| Previous filler of unknown identity | What can be dissolved and how tissue may have changed | Not an automatic barrier | Record it before deciding how to layer treatment |
| A wish to match a specific photograph | Motivation and expectation | Usually not satisfied | Discuss what the face can realistically read |
When filler is deferred or redirected
- The dominant concern is sagging, a drooping brow or a descended cheek, and filler cannot correct ptosis.
- There is active infection, inflammation or broken skin over the intended area.
- You are pregnant or breastfeeding, or have an undiagnosed skin condition at the site.

Frequently asked questions
Does my age matter for filler candidacy?
It matters less than what the assessment finds. A younger patient with good tissue support and a specific volume deficit may be a straightforward candidate; an older patient with laxity may not be, regardless of age. The findings decide, not the birthday.
Can I have filler if I have an autoimmune condition?
That needs assessing rather than assuming. Some conditions and their treatments change the risk of delayed reactions and infection, and the relevant history should be documented before treatment. It is a conversation at assessment, not a rule that automatically excludes you.
What if I have had filler before and do not know what it was?
Say so. An unknown product changes the assessment: it affects what can be dissolved, how the tissue may have changed, and how a new treatment should be layered. Not knowing is common and is not a barrier, but it needs to be recorded.
Risks & Limitations
- Vascular occlusion — filler blocking a blood vessel. This is a time-critical emergency that can cause skin loss and, rarely, vision loss.
- Nodules, lumps or delayed inflammatory reactions, which may need treatment or dissolution.
- Infection at the injection site.
- Asymmetry or over-correction. Over-treatment is harder to correct than under-treatment.
- Migration of filler away from the intended area.
- Bruising and swelling. All filler results are temporary and maintenance treatment is required.
- Filler cannot correct tissue ptosis, and a thread lift is not a facelift.
When to Seek Care
- Severe pain out of proportion to the injection, or skin turning white, grey, mottled or dusky — a vascular emergency; seek care immediately.
- Any change in vision — seek emergency care immediately.
- Fever, spreading redness, warmth or pus at an injection site.
- A hard, painful lump that is growing, or redness and swelling appearing weeks to months after treatment.
- Skin breakdown, blistering or a dusky patch over a treated area.
