Dark circles under the eyes are a common concern, often making individuals appear tired or older. While fatigue is a well-known contributor, several other key factors can cause these dark shadows. Understanding these factors can help individuals make informed decisions about prevention and treatment options. In some cases, as the Cleveland Clinic explains, dark circles under the eyes can also indicate a need for lifestyle changes.
1. Lifestyle Factors
Certain lifestyle choices can significantly contribute to the development of dark circles. To better understand the impact of various lifestyle factors, refer to the table below:
| Lifestyle Factor | Impact on Dark Circles |
|---|---|
| Lack of Sleep | Insufficient sleep can cause the skin to become pale and thin, making blood vessels more prominent, as noted by the Cleveland Clinic. |
| Stress | Taban MD’s blog highlights that stress can dilate blood vessels and increase blood flow to the under-eye area, making dark circles more noticeable. |
| Excessive Alcohol Consumption | The Cleveland Clinic also points out that alcohol can dehydrate the body and thin the skin, exacerbating the appearance of dark circles. |
| Smoking | As explained by Taban MD, smoking restricts blood flow and damages collagen, leading to thinner skin and more visible dark circles. |
| Sun Overexposure | Excessive sun exposure can trigger melanin production, leading to hyperpigmentation and darkening of the under-eye area, as detailed by Healthline. |
| Eye Strain | Healthline also mentions that prolonged screen time or reading can cause blood vessels around the eyes to dilate, contributing to dark circles. |
| Rubbing Eyes | Rubbing your eyes can worsen dark circles by stretching the skin and damaging capillaries. |
Diet and Hydration
- A diet high in salt can cause water retention and puffiness, making dark circles more prominent.
- According to The Body Shop, dehydration can make the skin under the eyes appear dull.
2. Medical Conditions
Several medical conditions can also cause or worsen dark circles:
- Allergies: Allergies can cause inflammation and congestion in the sinuses, leading to dark circles.
- Anemia: The Cleveland Clinic explains that iron deficiency anemia can reduce oxygen flow to the tissues, making the skin appear pale and dark circles more noticeable.
- Thyroid Conditions: As detailed by the Cleveland Clinic, thyroid disorders can affect skin pigmentation and contribute to dark circles.
- Dermatitis: Skin conditions like eczema can cause inflammation and discoloration around the eyes.
- Eye Drop Treatment for Glaucoma: Certain eye drops used to treat glaucoma can cause dark circles, as reported by the Cleveland Clinic.
- Medications: Healthline notes that some medications can also contribute to the appearance of dark circles.
- Vitamin Deficiencies: Deficiencies in iron (anemia) and vitamin B12 may be linked to dark circles.
3. Genetic Factors
Genetics play a significant role in the predisposition to dark circles. Inherited traits that can contribute include:
- Thin Under-Eye Skin: Individuals with naturally thin skin under the eyes tend to have more prominent blood vessels, leading to dark circles.
- Hyperpigmentation: Genetic factors can influence melanin production, leading to increased pigmentation and darker skin under the eyes. This is especially prevalent in individuals with medium-dark skin tones.
- Facial Structure: Deep-set eyes or prominent depressions under the eyes can create shadows that resemble dark circles.
- Time of Manifestation: A genetic predisposition to dark circles can be present from birth or may appear later in life.
4. Aging
Aging is a primary contributor to the development of dark circles. As we age, several changes occur in the delicate skin around our eyes that make dark circles more prominent. These changes include:
- Thinning Skin: The skin under the eyes is naturally thin, and it becomes even thinner with age due to a decrease in collagen and elastin production, as mentioned by the Cleveland Clinic. This thinning makes the blood vessels beneath the skin more visible, giving the appearance of dark circles.
- Loss of Collagen and Elastin: Collagen and elastin are proteins that provide structure and elasticity to the skin. Taban MD explains that as we age, the production of these proteins declines, leading to a loss of skin firmness and elasticity. This can cause the skin to sag and wrinkle, making dark circles more noticeable.
- Reduced Fat: The area under the eyes also loses fat with age, which can create a hollowed-out appearance known as tear troughs, as explained by the Cleveland Clinic. These troughs can cast shadows that worsen the appearance of dark circles.
- Decreased Blood Circulation: The Body Shop highlights that aging can also impair blood circulation, leading to a buildup of blood and fluid in the under-eye area. This can cause puffiness and dark shadows.
While aging is a natural process, certain lifestyle factors can accelerate these changes and worsen the appearance of dark circles. These factors include excessive sun exposure, smoking, and poor diet, as highlighted by Taban MD.
5. Red Light Therapy for Dark Circles
Red light therapy, a non-invasive treatment using red and near-infrared light, has shown promise in addressing various skin concerns, including dark circles. While research is ongoing, studies suggest that red light therapy can offer several benefits for the under-eye area:
- Increased Collagen Production: Infraredi Australia explains that red light therapy stimulates the production of collagen and elastin, essential proteins for skin firmness and elasticity. By boosting collagen, red light therapy can help thicken the skin under the eyes, making blood vessels less visible and reducing the appearance of dark circles.
- Improved Blood Circulation: Red light therapy enhances microcirculation by promoting the dilation of blood vessels, as detailed in this article by Infraredi Australia. This improved blood flow helps to reduce the pooling of blood under the eyes, which is a major contributor to dark circles. It also ensures that skin cells receive adequate oxygen and nutrients, promoting overall skin health and a more vibrant appearance.
- Reduced Inflammation: Inflammation can contribute to puffiness and discoloration under the eyes. The anti-inflammatory properties of red light therapy, as discussed by Infraredi Australia, can help reduce swelling and improve the appearance of dark circles.
While red light therapy shows potential for treating dark circles, it’s important to note that individual results may vary. Factors such as the severity of dark circles, skin type, and the specific device used can influence the effectiveness of the treatment.

Conclusion
Dark circles under the eyes can be caused by a complex interplay of lifestyle factors, medical conditions, genetics, and aging. These factors are often interconnected; for example, stress can disrupt sleep patterns, leading to fatigue and more prominent dark circles. By understanding these key factors, individuals can take proactive steps to minimize their appearance.
Addressing the underlying causes is crucial. This may involve lifestyle modifications such as improving sleep habits, reducing stress, and protecting the skin from the sun. Treating medical conditions like allergies or anemia can also improve dark circles.
For those seeking cosmetic solutions, options include topical creams, chemical peels, laser therapy, and injectable fillers. Red light therapy, as mentioned earlier, may also offer a potential solution. Ultimately, a comprehensive approach that considers individual needs and underlying causes is essential for effectively addressing dark circles.
