Where malar oedema matters on this site
Malar oedema is one of the main reasons this site advises against under-eye filler for some people, and one of the problems it helps people sort out afterwards. The pages below are where it is distinguished, assessed and managed.
Across those pages the rule is consistent: puffiness that fluctuates is understood before anything is injected.
Not to be confused with
Swelling under the eye has several causes, and only some of them involve filler.
- A true eye bag. Orbital fat pushing forward behind the septum. It looks much the same from morning to evening, and filler is not its answer.
- Festoons. Lax skin and muscle forming a mound over the cheekbone. They often coexist with malar oedema but contain lax tissue as well as fluid.
- The Tyndall effect. A bluish tint from superficial hyaluronic acid. It is a colour change, not a swelling.
- Morning puffiness. Ordinary fluid shift after sleep, salt or alcohol that settles through the day. Malar oedema is the more persistent, localised version of the same tendency.
- Medical swelling. Puffiness that is new, one-sided, painful or red, or that comes with swelling elsewhere, is checked medically first, because thyroid, kidney, allergic and other causes can present this way.
The under-eye filler lumps page covers the firm swellings that are filler rather than fluid.
What decides whether malar oedema matters for you
Whether you are considering filler or dealing with swelling after it, the same questions decide the plan.
- Does it fluctuate? Fluid tends to be worse on waking and after salt, alcohol or poor sleep. Filler tends to be constant, with an edge on gentle palpation.
- Filler history. When it was placed, how much, and whether more was added later. Larger volumes and placement above the malar septum raise the risk.
- What the scan shows. Dr Sin Yong uses ultrasound to see whether gel is present, how deep it is and whether it sits above the malar septum.
- Medical causes. These are excluded first when the pattern is unusual.
- The skin afterwards. Where the skin itself is lax once swelling has settled, tightening is considered as a separate step.
Filler is not added to a puffy area to disguise it, and swelling that is hot, red and painful after filler needs immediate review.
