The tear trough is filled to a shape. Rapid pharmacologic weight loss keeps changing that shape for months after the injection. Almost every consultation covers what filler does and none of them cover what your face is going to do underneath it.

Under the LidVision loss from filler is rare, sudden and almost always immediate, which means the variable that matters most is not the injector's technique but whether anyone in the room knows what to do in the first sixty minutes.

Hyaluronic acid is chosen for the under-eye because it binds water, and that exact property is why the same filler can quietly puff and swell weeks later under the thinnest skin on your face.

ExplainerMalar edema is the most common reason tear trough filler backfires. Here is the mechanism, who is at risk, and the screening questions that predict trouble before a needle is opened.

ExplainerNot all hyaluronic acid gels behave the same way in the tear trough. Here is what the rheology labels actually mean, and why the wrong gel in the right hands can still cause puffiness.

ExplainerTwo under-eye problems look similar in the mirror but behave very differently under a needle. Here is how clinicians tell them apart, and why the distinction matters before anyone opens a syringe.

ExplainerDelayed puffiness after tear trough filler is not random bad luck. It comes down to lymphatic anatomy, the water-loving chemistry of hyaluronic acid, and where the product actually sits. Here is the mechanism, plainly.

Myth CheckThe 6 to 12 month lifespan quoted for hyaluronic acid filler comes from studies on other parts of the face. Imaging research suggests tear trough filler can persist far longer, and that has real consequences for how often you should top up.

ExplainerMany patients ask for under-eye filler and leave with midface filler instead. Here is the anatomical reasoning behind that recommendation, and how to tell which structure is actually causing your hollows.

Before you book
The best candidates have volume loss (hollowing) in the tear trough without significant skin laxity or festoons (chronic eyelid swelling). Pigmentary dark circles, vascular dark circles, and festoons typically don't respond to filler, and filler can make festoons worse.
