There are many reasons dark circles can appear under the eyes. These include lack or regular sleep, seasonal allergies and Vitamin B12 deficiency. Fortunately, there are a few treatments available that can help minimize your problem. Unfortunately, no one treatment is proven to be long-lasting. The following article will discuss some of the most common causes of dark circles under eyes. It is important to understand what dark circles are and how to treat them if you have them.
Lack of sleep
Dark circles around the eyes can be prevented by getting enough sleep. Insufficient sleep can make blood vessels under the skin more visible, which can lead to darker circles and paler skin. Dark circles can be minimized by getting at least seven to 8 hours sleep each night. It is possible that the age-related thinning of the tissue around your eyes could be contributing to dark circles. Laser therapy and fillers are both available to address these problems.
Anemia
Anemia is often seen as dark circles under the eyes. This is due to a deficiency of the mineral iron. This condition is caused by poor circulation, and lack of oxygen. The skin around eyes is thin and red blood cells transporting veins and capillaries are near the surface. The red blood cells and hemoglobin that are stored in these capillaries and veins can leak and get deposited below the eyes. This causes dark circles below the eyes.

Allergies seasonal
People with allergies often suffer from puffiness and dark circles under the eyes. The increased blood flow to your nose and eyes from nasal congestion can lead to these dark circles. The sensitive skin around the eyes can also be affected by allergies.
Vitamin B12 deficiency
Dark circles under the eyes can be a sign of Vitamin B12 deficiency. This vitamin is important for the health of nerves as well as blood cells. It is essential for the creation of DNA, the genetic material that is found in all cells. It can cause problems in the nervous system and heart as well as the brain.
Allergy triggers
Allergies can often cause puffy eyes which can lead dark circles under the eyes. Although there are over 140 food allergens, the majority of cases are caused by allergies to milk, shellfish, peanuts, or specific preservatives. It is impossible to eliminate all allergies, but there are ways to reduce their impact.
Retinoid creams
Retinoid-based creams for dark undereye circles can reduce puffiness. Some people are hesitant about using these creams, especially around the delicate eyes. You should do your research before you use these products.

Cucumber
Cucumber is rich in antioxidants, a compound that has been shown to reduce inflammation and prevent fluid accumulation under the eye. It helps to lighten dark circles, and soothes skin. It also has 95% water which makes it ideal for sensitive skin around your eyes.
Caffeine
Brightening serums have made caffeine a very popular ingredient for dark circles under the eyes. Caffeine can reduce puffiness, dark under-eye circles, and fine lines. It improves blood flow and oxygenation around the eyes.
