How Long Does Tear-Trough Under-Eye Filler Last?
Tear-trough under-eye filler typically lasts around 9 to 18 months, and often longer in this area than in more mobile parts of the face because the under-eye moves relatively little. How long it lasts for you depends on the product used, your metabolism, and the injector's technique — which is also what determines whether the result looks natural or puffy. At Face Injectables, a nurse-led med spa in Vaughan serving Toronto and the GTA, Advanced Nurse Injector Stephanie treats this area conservatively for results that both look and wear well.
The under-eye is one of the most rewarding areas to treat well and one of the least forgiving to treat poorly, so longevity is only half the question. Here's the full picture.
Why the Under-Eye Often Lasts Longer
Filler tends to break down faster in areas that move a lot, like the mouth. The tear-trough region is comparatively still, so the hyaluronic acid isn't constantly being worked by muscle movement. That's why many clients enjoy results here for well over a year before considering a refresh.
What Affects How Long It Lasts
The product. Different hyaluronic acid fillers have different densities and longevity. The right one for the delicate under-eye is chosen specifically for that area, not borrowed from a heavier filler used elsewhere.
Your metabolism. Everyone breaks down filler at a slightly different rate. A faster metabolism can shorten the timeline; this is simply individual variation.
Technique and placement. Correct depth and conservative volume don't just look better — they wear better. Over-filling or poor placement is the main cause of puffiness and uneven results, and it can also change how the filler settles over time.
How to Protect Your Results
Staying hydrated, protecting the area from sun, and following your injector's aftercare all help. Beyond that, the single biggest factor is choosing an experienced injector who treats the under-eye conservatively. Stephanie assesses the area carefully and uses a natural, restrained approach — which is exactly why clients seek her out for this specific treatment. Individual results vary.
When to Refresh
Most clients top up when they notice the shadow or hollow gradually returning, often somewhere between a year and 18 months. Because hyaluronic filler is adjustable, your look can be maintained and refined over time rather than done all at once.
Frequently Asked Questions
Can under-eye filler be dissolved if I don't like it?
Hyaluronic acid fillers can be dissolved by a qualified injector if needed, which is one reason many clients feel comfortable starting here.
Why does mine seem to fade faster than a friend's?
Metabolism, the product used, and the area all vary from person to person. Individual results vary.
Does under-eye filler cause puffiness?
Puffiness usually comes from over-filling or poor placement, not the treatment itself — which is why a conservative, experienced injector matters.
How often will I need it?
Many clients refresh somewhere between a year and 18 months, when the shadow gradually returns.
