Lack of sleep is one of the most common causes of under-eye dark circles. Sleep disorders or insufficient sleep can cause blood vessels in the skin under the eyes to widen and become prominent. Additionally, lack of sleep can cause fluid accumulation under the skin, causing swelling and bruising under the eyes. Therefore, getting enough sleep and paying attention to sleep patterns can help reduce under-eye dark circles.

Allergies and dark circles under eyes
Allergies can also contribute to under-eye dark circles. Especially seasonal allergies can cause itching, watering and irritation in the eyes. This may lead to the formation of dark circles and bruises under the eyes. If you have allergy symptoms, avoiding allergens or using medications recommended by your doctor may help reduce under-eye dark circles.

Genetic factors and under-eye dark circles
Dark circles under the eyes may also be affected by genetic factors. Some people may have a familial predisposition to dark circles under their eyes. If you have a genetic predisposition to prominent blood vessels under the skin or pigmentation problems under the eyes, you are more likely to develop dark circles under your eyes. In this case, although it is not possible to completely eliminate the effect of genetic factors, you can alleviate under-eye dark circles with some treatment methods.

Aging and dark circles under eyes
The aging process can also be effective in the formation of under-eye dark circles. As we age, the amount of fat and collagen under the skin decreases, which can cause thinning under the eyes and enlargement of pores. Additionally, blood vessels under the skin may become more visible during the aging process. All of these factors can contribute to the formation of under-eye dark circles. Although it is not possible to prevent or slow down aging, you can reduce under-eye dark circles with the right care and treatment methods.

Lifestyle factors that contribute to under-eye dark circles
Dark circles under the eyes can also be associated with lifestyle factors. Here are some lifestyle factors that contribute to under-eye dark circles:

Stress
Stress is an important factor in the formation of under-eye dark circles. A stressful lifestyle can cause the hormone cortisol to increase in the body and dilate blood vessels. This may lead to bruises and swelling in the under-eye skin. Practicing relaxation techniques to reduce stress can help reduce under-eye dark circles.

To smoke
Smoking is another lifestyle factor that contributes to under-eye dark circles. Smoking can reduce blood circulation to the skin and reduce the amount of oxygen. This can cause the under-eye skin to look pale and tired. Additionally, smoking can also reduce the amount of collagen in the skin, which can cause under-eye dark circles to become more noticeable. It is important to quit or reduce smoking to reduce under-eye dark circles.

Nutrition
Eating habits can also affect under-eye dark circles. Iron deficiency, in particular, can be an important factor in the formation of under-eye dark circles. Consuming iron-rich foods can help reduce under-eye dark circles. Additionally, drinking adequate amounts of water and consuming foods rich in antioxidants can also contribute to the reduction of under-eye dark circles.

Make-up is another method used to hide under-eye dark circles. Makeup products such as concealer and foundation can reduce the appearance of dark circles and bruises on the under-eye skin.
