Dark circles under the eyes are common in most men and women, and they can be stubborn to shift. They often knock people’s confidence. Some feel they look older because of them, whilst others feel they look tired or unwell. The cause varies from person to person, and that cause matters. The right approach depends entirely on why the circles are there in the first place. This article covers what causes dark circles and the treatments that help, from simple lifestyle changes to skincare and professional treatments.
What Causes Dark Circles Under the Eyes?
Dark circles appear when the skin under the eye looks darker than the surrounding skin. There is also rarely a single root cause, and most fall into a few underlying types. Identifying yours is the key to treating them:
- Hyperpigmentation: This is extra melanin in the under-eye skin. It is often genetic, more common in deeper skin tones and worsened by sun exposure. This type responds poorly to basic products, so it usually needs targeted brightening actives.
- Thinning and ageing skin: As we get older, the skin thins and loses fat and collagen. That then makes the darker blood vessels underneath more visible.
- Hollows and shadows: Loss of volume in the tear trough casts a shadow that looks like a dark circle under the eyes.
- Lifestyle: Poor sleep, dehydration, a salty diet, alcohol, smoking and low iron can all dull the complexion and deepen dark circles.
- Allergies and eyestrain: Hay fever and the rubbing it triggers can darken and puff up the delicate under-eye area.
Can a Medical Condition Cause Dark Circles?
Most dark circles are harmless and cosmetic. Occasionally, though, they point to something else, so it is worth knowing the possible medical links. The main ones to be aware of are:
- Allergies and eczema: Hay fever, allergic rhinitis and eczema cause congestion and rubbing around the eyes. This then leads to hyperpigmentation and is one of the most common medical causes of under-eye darkening.
- Iron-deficiency anaemia: Low iron can leave the skin pale and sallow, which makes the vessels under the eyes more obvious.
- Thyroid problems: An underactive or overactive thyroid can change the skin and the tissues around the eyes.
- Nasal and sinus congestion: Blocked sinuses dilate the small veins around the eyes. This makes them more visible and which then make the under eyes look darker.
- Dehydration and fatigue: Illnesses that disrupt fluid balance or sleep can worsen the appearance.
If a medical cause is likely, treating the underlying condition usually helps the dark circles far more than skincare or professional treatments alone.
How Do Lifestyle Habits Affect Dark Circles?
Daily habits have a real influence on how prominent dark circles look. Adjusting them is often the first and cheapest step. The ones that make the biggest difference are:
- Sleep: Getting enough good-quality sleep is one of the most effective changes. Poor sleep makes the skin look paler and the shadows more obvious.
- Diet and iron: A balanced diet with enough iron supports a healthy complexion. A poor diet can lead to iron deficiency which can manifest as dark under eye circles.
- Hydration: Drinking enough water and easing off salt keeps fluid balance steady. This then reduces the puffiness that casts shadows and makes dark circles look more severe.
- Alcohol and smoking: Both dehydrate the skin and deposit toxins that dull the complexion, so cutting back helps the area look brighter.
- Sun protection: Daily SPF and sunglasses limit the UV exposure that deepens pigment under the eyes.
- Screen breaks and gentle handling: Resting tired eyes and avoiding rubbing can help reduce the irritation and the appearance of dark circles.
Can You Treat Dark Circles at Home?
Some dark circles are mainly down to lifestyle factors like dehydration or poor sleep. The good news is that these often respond to simple measures at home:
- Sleep and head elevation: Catching up on sleep is one of the most effective things you can do. Propping your head on a pillow also stops fluid pooling around the eyes, which reduces puffiness.
- Cold compresses: A cold compress or chilled tea bag can temporarily constrict the blood vessels and soften their appearance. The caffeine and antioxidants in tea also help with this.
- Hydration and diet: Staying well hydrated, cutting back on salt and going easy on alcohol and caffeine all reduce the puffiness that deepens shadows.
- Allergy control: Managing allergies such as hay fever stops the itching and rubbing that darken the area.
- Colour-correcting concealer: For a quick fix, a concealer in a peach or salmon tone can help cancel out the darkness under the eyes.
What is the Best Skincare for Dark Circles?
If your under-eye circles are due to hyperpigmentation or thin skin, the right skincare can make a real difference. The skin here is the thinnest and most delicate on the face. For that reason, use these actives at lower strengths and in gentler, more hydrating formulas than elsewhere on the face. The most useful ingredients for the area are:
- Niacinamide: This gentle, well-tolerated brightening agent fades pigment, strengthens the barrier and boosts hydration. This is why niacinamide is well suited to the delicate under-eye area.
- Antioxidants: Vitamin C and ferulic acid help brighten the skin and protect against environmental damage. To avoid irritation around the eyes, opt for a lower concentration or gentler form of vitamin C.
- Hydroquinone: This is the prescription gold standard for lightening stubborn pigment. Near the eyes, doctors sometimes also use hydroquinone at lower strength and for short courses.
- Retinoids: Over-the-counter retinoids and prescription ones like tretinoin can fade hyperpigmentation, boost collagen and gradually thicken thin under-eye skin. They usually need slow introduction, at a low strength and buffering with moisturiser, since the area irritates easily and can lead to to dry eyes.
- Supporting ingredients: Agents like caffeine, hyaluronic acid and peptides can improve hydration and elasticity and temporarily reduce puffiness. This helps to soften the look of hollows and shadows and indirectly brighten the skin.
What Medical Treatments are Available for Dark Circles?
When dark circles come from structural changes like hollowing or volume loss, topical skincare can only do so much. In-clinic procedures sometimes address the cause more directly. In-person aesthetic clinics carry these out rather than online clinics and the main options include:
- Chemical peels: These resurface the upper layers of skin and can help dark circles driven by hyperpigmentation, gradually evening out tone.
- Tear trough filler: An injectable treatment that adds volume to under-eye hollows. This then reduces the shadowing that creates the look of dark circles.
- Microneedling and radiofrequency microneedling: These stimulate collagen to thicken thin under-eye skin over a course of sessions. They might also help with mild hyperpigmentation.
- Injectable skin boosters: Treatments such as Profhilo are hyaluronic acid injectables that hydrate and stimulate collagen to improve skin quality.
- Laser treatment: Laser therapy can target stubborn hyperpigmentation and the visible vessels that contribute to dark circles.
City Skin Clinic is an online clinic that provides personalised prescription-strength skincare, so we do not offer injectables, in-clinic chemical peels, laser or microneedling. Where hyperpigmentation or thin skin drives the dark circles, our doctors can help with bespoke topical treatments for certain under-eye concerns. However, for extensive, structural or volume-related dark circles, you may need to consider professional treatments. For this, you should find a medical clinic with experienced and qualified practitioners for the above procedures. For severe hollows or under-eye bags then you might also want to get a consultation with an oculoplastic surgeon as these may require surgery.
Getting rid of dark circles starts with knowing what is causing them. Lifestyle changes and over-the-counter eye creams are enough for mild, fatigue-related shadows. However, extensive hyperpigmentation and thin skin may need prescription actives like hydroquinone or a retinoid. These work best at the low strengths and formulas suited to the area. Structural circles from hollows or severe hyperpigmentation may respond better to in-office procedures. In practice, the most stubborn cases often need a combination. If your dark circles appear suddenly, change quickly or affect only one eye, see a doctor first. A medical review can rule out an underlying cause.
Our online skin clinic offers safe and effective custom skincare treatments. Where appropriate our doctors use ingredients such as tretinoin and hydroquinone to treat skin conditions like acne, hyperpigmentation, melasma and skin ageing.
