In short. Descent, skin laxity and a medical cause all change a face without reducing its volume. In those cases both fat transfer and filler are the wrong answer.

Key points

  • Volume loss is treated with volume.
  • Descent is treated by repositioning tissue.
  • Laxity is treated by removing or tightening skin.

Both options in this comparison add volume. That makes them useful for one kind of change and useless for the others, and a patient whose face has changed for a different reason is being offered the wrong treatment however well it is performed.

Descent rather than volume loss

Tissue that has moved downwards has not emptied. It sits lower than it did, and the change shows as a different position of the cheek, the jawline or the mid-face rather than as a hollow. Adding volume to a face in that state fills the place where the tissue now is, which is lower than where it was, and the result tends to look fuller rather than lifted. That is not a failure of the material; it is a mismatch between the material and the finding. A face whose main change is descent is assessed for an operation that repositions tissue, and volume may then be part of that plan rather than the whole of it.

Skin laxity

Skin that has loosened changes the contour of a face without any change in the volume beneath it. Adding volume under lax skin does not tighten the skin, and in some faces it makes the laxity more visible by giving the skin more to drape over. The assessment that separates laxity from volume loss is an examination of how the skin behaves rather than a comparison of photographs, and the treatments are different.

Three findings, three different answers

Volume loss is treated with volume. Descent is treated by repositioning tissue. Laxity is treated by removing or tightening skin. Neither option in this comparison addresses the second or the third, and naming which one is present is most of the assessment.

A medical cause

Some changes in facial volume are medical rather than cosmetic. A rapid change, a change on one side only, a change accompanied by other symptoms, or a change in a patient with a relevant medical history is assessed as a clinical problem before any plan for volume is made. That is not a formality: treating a medical cause with volume leaves the cause unaddressed, and it delays the assessment that would have identified it.

Where the boundary sits

The boundary is not between patients who want treatment and patients who do not. It is between a face whose change is volume and a face whose change is something else, and it is found by examination. A patient who is told that volume treatment is not the right answer is being given a finding rather than a refusal, and it is worth asking what the finding was and what the alternative is.

Where volume is the wrong answer

  • A face whose main change is descent, where the right next step is an assessment for repositioning rather than an injection.
  • Lax skin, which volume does not tighten and can make more visible.
  • A rapid, one-sided or symptomatic change, which is assessed medically before anything cosmetic is considered.

Volume is worth adding where volume has been lost. Deciding that is not the same as deciding which material to use, and it comes first. A patient who has that answered has a shorter and more useful conversation about the two options than one who has not.

Frequently asked questions

How can I tell whether my face has lost volume or descended?

By what has moved rather than by what has emptied. Volume loss shows as a hollow or a flattening; descent shows as tissue sitting lower than it did, with the cheek or the jawline in a different position. A mirror and a photograph from several years earlier are useful, and the distinction is made properly at an examination because the two often occur together.

Can filler lift a face that has descended?

It can add volume where tissue has dropped, and that is not the same as repositioning it. Adding volume to a descended face often makes it look fuller in the wrong place rather than lifted, and the patient may be describing a change the treatment cannot make. A surgical assessment is usually the right next step for a face whose main change is descent.

What medical causes can change facial volume?

A number of conditions and treatments can, including some that affect weight and some that affect the skin or the connective tissue. A change that is rapid, one-sided, or accompanied by other symptoms is assessed medically rather than cosmetically, and that assessment comes before any plan for volume.

Risks & Limitations

  • No result can be guaranteed, and only part of any grafted fat survives.
  • Transferred fat cannot be dissolved; only a portion can be removed surgically.
  • Filler is absorbed over months and the result is temporary.
  • Lumps, irregularity and, rarely, vascular occlusion can occur with either option.

When to Seek Care

  • Severe pain, blanching or a colour change in the skin after an injection — seek care immediately.
  • Vision change or eye pain after a facial injection — this is an emergency.
  • Fever, or spreading redness, warmth or discharge from a treated or donor area.
  • A lump that is growing, painful, or accompanied by redness or warmth.
