Dark circles or hollows? Tear trough filler and other under-eye treatments compared
Quick answer: dark circles under the eyes usually come from one of four things: a hollow that casts a shadow, pigment in the skin, puffiness or malar bags, or thin, crepey skin that lets veins show through. Tear trough filler can help a true hollow, polynucleotides can help thin skin, and skincare is the starting point for pigment. The only reliable way to know which one you have is an assessment by an experienced practitioner.
"Would tear trough filler work for me?" is one of the most common questions people post online, usually with a close-up photo and a lot of conflicting replies. Some are told filler changed everything. Others are told it made their under-eyes puffier. Both can be true. "Dark circles" only describes how the area looks, and the cause can be quite different from one person to the next.
This guide helps you work out what's behind your under-eyes and which treatment is likely to suit you. At NassifMD, every under-eye treatment starts with a consultation, and if we don't think a treatment will help you, we'll tell you.
How our experts assess your under-eyes
The under-eye is one of the most delicate areas of the face, and it's where good assessment matters most. Our medically led team looks at the whole picture before recommending anything:
- Your anatomy. Where the cheek meets the lower lid, how deep the hollow is, and how light falls across it.
- Your skin. How thin it is, its colour and texture, and whether veins show through.
- Your lifestyle. Sleep, hydration, diet (including salt intake) and whether you sleep on your side can all affect how filler behaves under the eye.
- Your tendency to swell. Some people hold more fluid under the eyes, which changes what we'd recommend.
From there, we tailor a plan to you. That might be one treatment, a combination, or simple lifestyle and skincare advice. In line with Dr Paul Nassif's approach, the aim is always a natural-looking result: you, looking refreshed.
What causes dark circles under the eyes?
Many people have more than one cause.
1. Hollows and shadows (tear troughs)
As we age, we lose volume where the top of the cheekbone meets the under-eye. This groove is the tear trough. As it deepens, it casts a shadow that reads as a dark circle. A quick check: if the darkness looks worse under overhead light and mostly disappears in soft light from the front, a hollow is likely playing a big part.
2. Pigment
Some dark circles are a brown or darker tone in the skin itself. It often runs in families. If you gently stretch the skin and the colour stays, pigment may be the main cause. Filler adds volume. It doesn't change skin colour, so pigment usually needs a skincare-led approach.
3. Puffiness and malar bags
Puffiness that's worse in the morning, after salty food or a late night often comes from fluid. Malar bags are soft, swollen areas that sit lower down, on the top of the cheekbone. Both can create shadows, but adding filler to a puffy area can make it look heavier. This is one of the most common reasons we advise against tear trough filler.
4. Thin, crepey skin
The skin under the eyes is thinner than anywhere else on the face. As collagen and elastin naturally decline, it becomes less hydrated and less able to bounce back. Veins underneath can show through, giving a blue or purple tinge, and fine crepey lines appear.
Am I a good candidate for tear trough filler?
You may be a good candidate if:
- Your darkness is mainly a shadow from a visible hollow or groove
- The skin under your eyes has reasonable thickness and quality
- You don't have much puffiness or fluid that comes and goes
- You want a subtle, refreshed look rather than a dramatic change
Tear trough filler restores lost volume, following the natural contours of the face. Treatment takes 15 to 30 minutes and uses filler with local anaesthetic to keep you comfortable. Results are visible straight away and settle as any swelling eases, and they can last a long time, often 12 months or more, with top-ups to maintain them. We use non-permanent filler that can be reversed if needed. You can read more in our guide to tear trough filler for under-eye concerns.
When tear trough filler isn't the answer
We only treat someone we believe will benefit. Filler is often not the right first choice if your main concern is:
- Puffiness or malar bags. Filler can hold water and make swelling look worse.
- Pigment. Volume won't lift colour from the skin.
- Very thin, crepey skin on its own. Improving skin quality usually comes first.
In these cases we'll recommend another route and explain why.
Polynucleotides or filler for under-eyes?
They do different jobs, and they can work well together.
- Tear trough filler replaces lost volume to soften a hollow.
- Polynucleotides aren't a filler. They're a bio-stimulant that encourages your skin to produce more collagen and elastin and improves hydration. They can help the quality, thickness and tone of thin under-eye skin.
Polynucleotides are usually given as a course of 2 to 3 treatments, a few weeks apart, and the effect builds over that time. You may see small bumps, redness or slight swelling at the injection points, which typically settle within 24 to 48 hours. We may also suggest skin boosters such as Teoxane Redensity 1. Find out more in our post on polynucleotides for under-eyes or on our polynucleotides treatment page.
Can an eye cream fix dark circles?
An eye cream won't fill a hollow or remove a malar bag. For pigment and dullness, a consistent medical-grade skincare routine can make a real difference over time, and good skincare supports every other treatment. Good sleep, hydration and less salt help too. We can recommend products for your skin during your consultation, or you can browse our skincare range.

Frequently asked questions
Am I a good candidate for tear trough filler?
You may be if your dark circles are mainly a shadow from a hollow, your under-eye skin has reasonable quality and you don't have much puffiness. Every patient is assessed at consultation, and we'll only treat you if we believe you'll benefit.
Polynucleotides or filler for under-eyes?
Filler replaces lost volume to soften a hollow. Polynucleotides improve the quality, thickness and hydration of thin under-eye skin. Many people benefit from one or the other, and some from both.
Can an eye cream fix dark circles?
An eye cream can't fill a hollow or remove puffiness. Medical-grade skincare can help pigment and dullness over time and supports any treatment you have.
What are malar bags and can filler help?
Malar bags are soft, swollen areas on the top of the cheekbone. Filler isn't usually the right choice for them, because it can hold water and make them look heavier. We'll talk you through other options at consultation.
How long does tear trough filler last?
Tear trough filler can last a long time, often 12 months or more. It is temporary, so top-ups are needed to maintain the effect.
Is there any downtime after tear trough filler?
Most people carry on with their day as normal. The area can feel sensitive for up to 48 hours, and minor swelling, lumps or bruising can happen and usually settle within 48 hours. If you notice skin colour changes, severe pain or changes in your vision, contact us straight away, and if you're ever in doubt go straight to A&E.
