Dark circles & under-eye bags: Identify causes and treat specifically
From hyaluronic acid to lower eyelid surgery. An honest assessment of the FORUM Klinik Köln.

A tired look, even though you are well-rested? Dark circles and bags under the eyes are among the most common reasons why the face looks exhausted – and among the most misunderstood. This is because "dark circles" are not a single, uniform phenomenon: sometimes they are discoloration, sometimes shadows, sometimes protruding fat. That is exactly why there is no such thing as the one and only treatment. This guide explains in detail which causes lie behind them – and which method really helps for which cause.
First of all, and it is the most important sentence of this text: the result is determined by the careful analysis before the treatment. Anyone who recognizes the correct cause treats it in a targeted manner – instead of missing the problem. At the FORUM Klinik in Cologne, we take our time for this and advise you honestly, even where the limits lie.
The Essentials in Brief
Dark circles have several potential causes: pigment discoloration, translucent vessels due to thin skin, a sunken tear trough (loss of volume), and bags under the eyes that cast shadows.
Bags under the eyes are protruding fat pads under the eye – a distinct cause of dark circles.
Depending on the cause, different things help: hyaluronic acid for a sunken tear trough, a lower eyelid lift for true bags under the eyes or excess skin, skin care and sun protection for pigmentation.
The wrong method for the wrong cause leads to disappointment – the diagnosis is what matters.
Dark circles – why do we look tired? The four main causes
"Dark circles" is a collective term. Behind it lie very different mechanisms, often also in combination:
Pigment-related dark circles. An increased accumulation of melanin makes the lower eyelid skin appear brownish. This form is often genetic or constitutional and is worsened by the sun.
Translucent vessels under thin skin. The skin on the lower eyelid is the thinnest on the body. If the underlying blood vessels shimmer through, a bluish-violet tone is created – typical for very fair or thin skin.
Sunken tear trough. Over the years – sometimes also by nature – the region at the transition from the lower eyelid to the cheek loses volume. This creates a depression that casts a shadow and makes you look tired.
Bags under the eyes. Protruding fat under the eye creates a small step – and thus also a shadow. Bags under the eyes are therefore not the opposite of dark circles, but one of their causes.
In addition, there are lifestyle factors such as lack of sleep, too little fluid, high salt or alcohol intake, smoking, and UV radiation. These primarily intensify the temporary swelling and discoloration components – they do not change the structural causes.
Bags under the eyes – what lies behind them?
In colloquial language, "bags under the eyes" refers to the fat pads under the eye that stand out through the skin and make us look exhausted. They are often more pronounced in the morning, and the shadowing created by the protrusion is particularly bothersome.
With age, the fine support structures that hold back the orbital fat slacken – the fat bulges forward. This is often accompanied by a slackening of the lower eyelid skin. It is important to distinguish this from pure, temporary swelling (e.g., after salty food or too little sleep): true bags under the eyes are a structural change, not water retention that disappears over the course of the day.
Treating dark circles & bags under the eyes – which method for which cause?
Here lies the core: first the cause, then the method.
Sunken tear trough → Hyaluronic acid fillers
If the reason lies in a loss of volume – i.e., a sunken tear trough that casts a shadow – a subtle injection with hyaluronic acid can gently smooth the transition to the cheek and soften the shadow. We work according to the structured MD-Codes® methodology: dosed, precise, and along natural proportions – not "filled up", but harmonious.
The treatment usually takes only 15–40 minutes, is outpatient, and generally allows you to resume daily activities immediately; fine-tuning takes place after 10–14 days. The result typically lasts 6–18 months and is controllable and reversible – if necessary, hyaluronic acid can be dissolved again with hyaluronidase. The tear trough in particular requires a very precise, safe injection plane; we do not treat during pregnancy and breastfeeding. For pure pigmentation or true fatty bags under the eyes, however, fillers are not the right way.
Bags under the eyes & excess skin → Lower eyelid lift
If true bags under the eyes or excess skin are the cause, fillers will not help – here, the lower eyelid lift is the targeted approach. In younger patients, the excess fat can often be corrected from the inside through the conjunctiva (transconjunctival) – completely without an external incision and therefore without visible scarring. If skin laxity is also present, the procedure is combined with an eyelid skin tightening.
A modern approach to this: instead of simply removing the fat, we like to use the valuable, living autologous fat to even out the sunken tear trough. This tightens the skin, eliminates the protrusion, and softens the tired "hollowness" of the midface – the causes are addressed together.
Regarding the procedure: no blood-thinning agents and no aspirin 14 days before the surgery; the operation is usually performed under twilight sleep or general anesthesia, as an outpatient or, if desired, inpatient. In follow-up care, you treat the region with an eye ointment; stitches are removed after about 3–5 days, and remaining bruises can easily be covered with makeup after around a week. The careful pre-analysis remains crucial – it prevents too much or too little correction.
Pigment-related dark circles → Skin care & sun protection
For pigment-related dark circles, surgery would be the wrong tool: neither fillers nor a procedure will change melanin discoloration. Here, we rely on medical skin care, consistent sun protection, and, if necessary, supplementary skin treatments to improve the skin texture. To be honest, the possibilities here are more limited – making the correct classification all the more important.
Translucent vessels → Combined strategy
If vessels shimmer through thin skin, a cautious volume build-up in the tear trough can visually calm the area and reduce the shadow. Here, too, the result depends on the quality of the skin, and we discuss the realistic limits openly.
Lifestyle – the foundation
Sufficient sleep, enough fluids, less salt and alcohol, quitting smoking, and UV protection primarily reduce the temporary swelling and discoloration components. They are a sensible foundation – but do not replace targeted treatment for structural causes.
Why the correct diagnosis determines the result
The most common disappointment arises when the method does not match the cause: fillers in the case of true fatty bags under the eyes can even accentuate the protrusion; surgery for pure pigmentation achieves nothing. That is why "getting rid of dark circles" does not begin with the choice of a treatment, but with clarifying the cause – pigment, vessels, volume loss, or bags under the eyes. Only then can it be determined what makes sense.
Getting rid of dark circles in Cologne – our approach
During the consultation, we analyze the entire lower eyelid region: How is the skin quality? Do vessels shimmer through? Is the tear trough sunken? Are there true bags under the eyes or excess skin? From these findings, we derive the appropriate recommendation – from subtle hyaluronic acid treatment to skin care and lower eyelid lifts. And if a cause can only be treated to a limited extent, we will tell you that honestly too. In this way, "getting rid of dark circles in Cologne" does not become a promise, but a realistic, individual plan.
Frequently Asked Questions (FAQ)
What is the difference between dark circles and bags under the eyes? Dark circles is a collective term for discoloration and shadows under the eye. Bags under the eyes – protruding fat – are one of their possible causes.
Can you treat dark circles with hyaluronic acid? In the case of a sunken tear trough, yes: a subtle injection softens the shadow. For pure pigmentation or true fatty bags under the eyes, hyaluronic acid is not suitable.
When is a lower eyelid lift useful? When true bags under the eyes or excess skin are present. Often, the excess fat can be corrected from the inside, without an external incision.
Will scars remain after a lower eyelid lift? With correction from the inside (transconjunctival), no visible scar remains. If the procedure is performed from the outside, the fine incision runs just below the lash line and is later inconspicuous.
Do creams or home remedies help against dark circles? They can alleviate the temporary swelling component and care for the skin appearance, but they do not change structural causes such as bags under the eyes or a sunken tear trough.
Is hyaluronic acid in the tear trough safe and reversible? The region requires a precise, safe technique. The result is controllable and, if necessary, can be dissolved again with hyaluronidase.
How much does the treatment of dark circles or bags under the eyes cost? That depends on the cause and method. A personal cost plan will give you a binding sum after the consultation.
How do I find out what I need? Through a careful analysis of the lower eyelid region in a consultation – this is the foundation of any sensible recommendation.
Conclusion
Dark circles and bags under the eyes are not a single problem with a single solution. Pigment, translucent vessels, a sunken tear trough, and protruding fat each require a different path – from hyaluronic acid treatment to skin care and lower eyelid lifts. Anyone who receives honest advice chooses from the very beginning the method that matches the cause.
