Why do dark circles appear under the eyes ?
The eye contour is a particularly delicate region. Its skin is among the thinnest in the human body, three to five times thinner than the rest of the face. It contains few sebaceous glands, few collagen fibres and has a limited blood supply. This structure makes the periorbital area vulnerable to numerous aesthetic concerns : skin laxity, hollowing, pigmentation or venous congestion. It is also subject to constant muscular activity, as it contributes to facial expression. Together, all these factors contribute to dark circles appearing over time.
What are the different types of dark circles ?
There are different types of dark circles, each with a different origin and requiring specific management.
Hollow dark circles result from volume loss, often associated with ageing, fat loss or genetic predisposition. They appear as a pronounced shadow under the eye, giving the eyes a tired appearance.
Pigmented dark circles are characterised by a brownish colour. This type is more common in olive or dark skin and may appear in childhood. It is generally genetic in origin but can be aggravated by external factors such as sun exposure.
Vascular dark circles are caused by impaired venous and lymphatic microcirculation. The thin skin allows underlying vessels to show through, appearing bluish, purplish or grey. Lack of sleep, stress or certain medicines can accentuate this phenomenon.
Mixed forms combining pigmentation, hollowing and a vascular component are common. In these cases, a detailed analysis of the eye contour identifies the dominant cause and guides treatment.
What are the main causes of dark circles ?
Dark circles are the visible result of a structural, pigmentary or circulatory imbalance in the periorbital area. Several factors may play a role, alone or in combination.
- Genetics : familial predisposition is one of the determining factors. Some people have pronounced orbital hollowing, localised pigmentation or a deficient blood supply in the lower eyelid from adolescence. These hereditary forms are often resistant to conventional cosmetic treatments.
- Skin ageing : with age, the skin loses density, elasticity and its ability to retain water. Supporting tissues become lax, volumes shift, and infraorbital fat may migrate or diminish. This natural process accentuates hollowing and makes dark circles more visible.
- Fatigue and lifestyle : lack of sleep, chronic stress, poor hydration or an unbalanced diet make dark circles more visible by slowing microcirculation and reducing tissue oxygenation. Alcohol and smoking also have a direct impact on skin quality and vascular tone.
- Sun exposure : UV radiation stimulates melanin production and promotes hyperpigmentation, particularly in people with darker skin or a predisposition to pigmentation marks. Prolonged unprotected sun exposure may intensify pigmented dark circles.
- Underlying conditions : certain conditions, such as chronic allergies, iron deficiency or some circulatory disorders, may encourage dark circles to appear or worsen. In some cases, it is therefore important to rule out a medical cause before considering aesthetic treatment.
Should dark circles under the eyes be treated ?
A thorough clinical examination is essential before any procedure. Precisely identifying the type of dark circle, its main cause and its progression over time allows the most appropriate treatment to be chosen.
Dark circles do not always need treatment. Some are subtle, stable and do not affect the appearance of the eyes. However, when they become a source of concern, treatment can be considered. Effective, safe solutions are now available that require no social downtime and are adapted to each type of dark circle.
- Hyaluronic acid injections are indicated to fill hollow dark circles, restore volume in the orbital and malar areas and reduce the infraorbital shadow.
- Mesotherapy improves skin quality and stimulates microcirculation, with a gradual, natural effect.
- Laser treatment or superficial chemical peels can improve dark circles caused by melanin pigmentation.
- In some cases, a combined approach is recommended, particularly for mixed dark circles.
Why do dark circles make you look tired ?
The attention given to dark circles is not solely due to their unattractive appearance. They also affect the social and psychological perception of the eyes. In our society, marked eyes are often perceived as reflecting an unbalanced lifestyle, chronic fatigue or even a degree of self-neglect. This interpretation can cause embarrassment or distress in patients who are nevertheless healthy and full of energy.
The eyes play a central role in social interaction. They express alertness, vitality and openness. Conversely, pronounced dark circles may unintentionally project an image of weariness or exhaustion. This is particularly true in the era of remote working and video calls, where the face — especially the eyes — is constantly exposed on screen.
Understanding this social and emotional dimension of dark circles allows treatment to be considered as more than a superficial pursuit : it is a way to restore aesthetic balance and a sense of identity, respecting the patient’s natural appearance and lived experience.
When should dark circles under the eyes be treated ?
There is no standard age to start treating dark circles. Everything depends on their nature, progression and the concern they cause. In some patients, dark circles are present from adolescence due to genetic predisposition. In others, they appear later, often in their thirties or forties, through the combined effects of skin ageing and lifestyle.
The appropriate time to intervene is generally when dark circles persistently change the face, particularly when they create a tired, sad or hollow appearance, even at rest. At this stage, a gentle, targeted medical approach may be proposed for prevention or correction : mesotherapy, chemical peels or hyaluronic acid injections.
Early intervention allows correction without transformation and helps anticipate the progression of facial ageing.
How can dark circles be treated according to their cause ?
Dark circles are a common aesthetic concern with multiple causes. A rigorous medical approach based on an accurate diagnosis allows targeted, effective treatments that respect facial balance to be proposed. In Geneva, aesthetic medical techniques offer effective solutions to restore bright-looking eyes without surgery or altering natural facial expression.
