Honest comparison

Tear trough filler or polynucleotides?

Both treat the tired under eye, but in opposite ways. Tear trough filler adds volume to fill a hollow. Polynucleotides regenerate the thin skin itself. The under eye is one of the most delicate areas on the face, so choosing the right approach matters. Here is the honest difference, who each suits, what it costs and when neither is the answer.

At a glance

Tear trough filler

A soft hyaluronic acid placed under the eye to fill a hollow and lift the shadow it casts.

Targets
A genuine hollow and the dark shadow it creates
Indicative cost
Roughly £300 to £700
Downtime
Minimal, but swelling and bruising are common here
Lasts
Around nine to eighteen months, and is dissolvable

Polynucleotides

A regenerative injectable that improves the quality of the thin under eye skin over a course.

Targets
Crepey, dull, poor quality under eye skin and texture
Indicative cost
Roughly £200 to £400 a session, usually a short course
Downtime
Minimal, small bumps that settle within a day
Lasts
Several months, then a maintenance session

The real difference

Tear trough filler adds structure. When the dark circle is mostly a true hollow, where the cheek meets the eye socket and casts a shadow, a small amount of soft hyaluronic acid can fill that dip so light no longer pools there. The change is immediate. The catch is that this is one of the most technically demanding areas on the face. Placed too superficially or in skin that retains fluid, filler can puff, look bluish or sit unevenly, which is why an experienced injector and honest patient selection matter so much. A reassurance is that the product can be dissolved if the result is not right.

Polynucleotides improve the skin. Derived from purified DNA fragments, they are injected to stimulate repair, hydration and collagen in the delicate under eye skin. They do not add volume, so they will not fill a deep hollow, but over a course they can make thin, crepey, dull skin look smoother and more even, which softens the look of dark circles that come from poor skin quality rather than a dip. Because the effect builds gradually, a short course followed by maintenance is the norm.

In short, filler is for a hollow and polynucleotides are for skin quality. Some people benefit from both, with polynucleotides preparing and improving the skin and a conservative touch of filler only where a true hollow remains.

Who each one suits

Choose filler if

Your dark circle is mainly a genuine hollow, your skin does not hold fluid easily, and you want an immediate change from a skilled injector.

Choose polynucleotides if

Your under eye skin is thin, crepey or dull rather than truly hollow, and you are happy with a gradual improvement over a course.

Sometimes both

Improving the skin first with polynucleotides, then placing a little filler only where a hollow remains, can give a more natural result than filler alone.

When the answer is neither

Dark circles have several causes and not all of them respond to either treatment. If the darkness is true pigmentation in the skin, topical care or specific lasers are a better fit. If the shadow comes from puffy bags caused by fat that has pushed forward, or from clearly loose, hanging skin, a surgical option such as lower eyelid surgery may be the only honest answer, and a careful practitioner will say so rather than masking the problem with filler. Tiredness, dehydration, allergies and genetics also play a part. The under eye is unforgiving, so a thorough assessment of what is actually causing your dark circles is worth more than rushing into any injectable.

Medical disclaimer

Both are medical aesthetic injectables for a delicate area and should be carried out by a qualified, experienced practitioner after an in person assessment. This page is general information, not medical advice. Possible effects include swelling, bruising, lumps, prolonged puffiness and, rarely with any injection, a serious vascular complication that can affect vision. Results vary and are not guaranteed. Always confirm your suitability with a qualified practitioner.
