Filler placed under the eye goes into about the quietest spot on your whole face, and where a gel sits has far more to say about how long it lasts than most people expect. Here's what that means for how long yours holds, plus plain answers to the three questions that always come along with this one.
How long tear trough filler lasts, honestly
Here's the part that can be said before anybody has seen your face. Under the eye, hyaluronic-acid filler is commonly reported to hold on longer than the same gel manages in a lip — reported by the people who've had it, mind, rather than promised by anybody, ourselves included. It's also why there's no month figure anywhere on our dermal fillers page, which tells you only that fillers biodegrade naturally, that how long they last varies with the area and the product, and that what to expect is something we'll go through at your consultation.
We keep to that, because a number handed over before anybody has seen your eyes is really a number about strangers. The broad picture is still worth having, though, and here the broad picture is good news.
Why the under-eye holds on to filler
Your lower lid does move. You blink thousands of times a day without ever deciding to, and your cheek comes up underneath it every time you smile properly. What it isn't is busy. A blink is one of the lightest things your face does, finished before you can notice it, and even a wholehearted smile asks less of the area than a single conversation asks of a mouth.
That matters, because movement is what hurries filler along. Tissue that works all day goes on working at the gel inside it, and wherever that happens the clearing runs faster. Almost none of it happens here. Why a mouth is the hardest place on a face to keep filler is laid out in how long lip filler lasts.
Then there's where the gel sits. Under the eye it goes in deep — down against the bone, underneath the layers that do the moving rather than up among them — so it holds the groove up from below and is largely left in peace down there.
And here's the odd part. Very little gel goes in under the eye, because the job is to bring a dip up to level rather than to add fullness, and a smaller amount is ordinarily the shorter-lived one. How much went in does genuinely count. It simply gets outvoted here, and what people commonly find is that a light touch holds on anyway — which tells you plainly which of the two has the louder say. Not how much gel there was. Where it went.
How the shadow comes back
Plenty of people are half expecting a particular morning, so it's worth saying early that there isn't one.
Think of a tube of toothpaste. Nobody has ever caught one getting emptier: you pick it up every single morning and it looks exactly as it looked the morning before, right up until the day you find yourself rolling it flat from the bottom, and there was never a day when it changed. One limit on that, mind. A tube goes down at a rate anybody could work out from how many people live in the house, and nothing here can be worked out in advance. Borrow the pace and leave the arithmetic where it is.
The shadow comes back the way it went. Your body takes the gel down in very small instalments, the ground gives up a little of its level as that happens, and the groove starts casting a bit more shadow than it did a while back. There's no step anywhere in it, and no night that does the whole thing at once.
Which is why the mirror is rarely the thing that tells you. What tells you is the question coming back — somebody checking whether you're all right, because you look tired — and that's very likely the question that had you reading about this in the first place. When it starts turning up again you have your answer, and you have it early, while the result is still one you're happy with.
And to settle the fear that sits under the whole question: no, you don't end up worse off than when you started. Filler under the eye only ever propped something up, so once it has gone the groove is simply the groove again, the same one you brought in, doing what it was doing before anybody touched it.
Does tear trough filler hurt?
Everybody wants this one settled before they book, and the answer is short. What people commonly report is a feeling of pressure and a sting that's brief, and it's over about as quickly as it arrives.
There's a plain reason it registers more here than the same needle does on a cheek. Lower-lid skin is thin, with a good blood supply sitting close underneath it, so very little stands between a needle and the things that do the feeling. Your body also guards your eyes more jealously than it guards the rest of you: you blink at a sudden movement long before you've had any say in it. A fair share of what people brace themselves for is that reflex rather than anything they end up feeling.
It's fine-needle work in very small amounts, so no single injection lasts long. And do say so if you're uncomfortable at any point — nobody would rather you sat quietly through it. If injectables in general are what you're weighing, does Botox hurt answers the same question for the other injectable on the menu.
Tear trough filler aftercare, in short
You'll be talked through aftercare before you leave, and those instructions beat this page every time, because they were decided with your own eyes in front of the person saying them. What's here is the why underneath them.
The area can be sensitive for a couple of days, and the first instruction is to let it be. Hands off above all: no pressing, no rubbing, no checking it with a fingertip, because gel that has only just been placed can still be nudged out of position before it has settled. Then there's the heat list — a hot shower, a bath you'd call hot, exercise that leaves you properly out of breath, the glass of wine that evening — and every item on it does the same single thing, which is raise the flow through a face already carrying a bit of extra fluid. Makeup has a time of its own, and we'll tell you at the appointment when to put it back on; the only reason to wait at all is that skin takes a few hours to close behind a needle.
One thing about this area in particular. The lower lid wears the loosest, roomiest skin on the face, which makes it the first place on anybody at all, treated or not, to show a night's fluid. So the morning after can look puffier than the evening before did, and that's swelling at its peak rather than anything having gone wrong. The full settling fortnight, bruising and all, is written out in lip filler aftercare, and most of it holds true for an eye. And ring us on 0161 526 2232 about anything that's bothering you rather than sitting on it. That's what the number is there for.
Is under-eye filler safe?
The answer starts with why this treatment leans so heavily on the person doing it. Nowhere else on you is the skin as thin as it is on the lower lid, and there isn't much beneath it either, so there is very little margin for the work to be even slightly out. Gel sitting too near the surface can raise a faint ridge, or read blue-grey through skin that fine, while too generous an amount recreates the puffiness somebody came in to lose.
So the amounts here stay conservative on purpose, and the work is done unhurriedly, reaching the result you agreed by degrees rather than in one go. It's also why this belongs with a medical professional at whatever clinic you end up choosing, and why it's an entirely fair thing to ask before you sit down anywhere: who is doing the injecting, and what qualifies them to do it? Every injectable at Broadway Retreat is given by experienced medical professionals in our CQC-registered clinic on Broadway in Manchester.
Keeping it, when it starts to go
Filler is a temporary thing by design, and that cuts in your favour as much as against it: nothing you decide here is binding, and anything you turned out not to like would leave of its own accord. When the shadow does begin coming back, holding on to the result is a simple business. We can plan maintenance appointments and keep it for as long as you want it, and because the fade shows itself early, there's never any hurry about booking one.
Come and get the answer for your own eyes
The general answer becomes yours at a consultation and not before. Arrange one at our clinic on Broadway in Manchester, or ring 0161 526 2232 if you'd rather ask a few things first.
We'll take a proper look, find out where your own darkness is coming from, and say straight out whether filler would improve it. If the answer is no, we say so, and we say what would actually help. And if you'd like the shadow itself explained before any of that, why the under-eye reads as tired is where that's done.
You'll know it's fading the same way you knew you wanted it done: somebody will ask whether you're all right. What sits between those two questions is a long stretch in which nobody, yourself included, has any reason to mention your eyes.
