Many factors can cause dark circles under your eyes. These could include lack of sleep or seasonal allergies. There are several treatments that can help you minimize the problem. There is no proven treatment that works long-term. Here are the top causes of dark circles around your eyes. It is important to be aware of the causes of dark circles under your eyes and how to get rid of them.
Sleep deprivation
Getting enough sleep is crucial to combat the appearance of dark circles around the eyes. Lack of sleep can cause blood vessels under the skin to appear more visible, causing the skin to become paler and more prone to dark circles. To minimize dark circles, you should aim to get seven to eight hours sleep each night. The age-related thinning of tissue around the eyes may be a contributing factor, but laser therapy and fillers are available to treat 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 your eyes is thin and the red blood cell-carrying capillaries and veins are very close to the surface. These capillaries and veins become dilated and red blood cells, along with their hemoglobin, are deposited under the eyes. As a result, this depletion of red blood cells causes dark circles under the eye area.

Seasonal allergies
People with allergies often suffer from puffiness and dark circles under the eyes. This is due to increased blood flow to the eyes and nose from nasal congestion. The skin around your eyes is sensitive and susceptible to allergies.
Vitamin B12 deficiency
Vitamin B12 deficit can result in dark circles around the eyes. This vitamin is important for the health of nerves as well as blood cells. It also plays an important role in the production of DNA, the genetic material found in all cells. This vitamin is essential for the brain, nervous system, and heart.
Allergy triggers
Allergies often lead to puffy eyes that can result in dark circles under the eye. 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. There are some people who are skeptical about these products, particularly around the delicate eye region. There are many things you need to know before using these products. It's best to do your research.

Cucumber
Cucumber is high in antioxidants. This compound has been proven to reduce inflammation and prevent fluid buildup under the eyes. It also helps lighten dark circles and soothes the skin. This vegetable also has 95% of water, which is great for sensitive skin near the eyes.
Caffeine
Brightening serums have made caffeine a very popular ingredient for dark circles under the eyes. Caffeine helps to reduce puffiness, dark undereye circles, and fine line. It can also boost blood flow around your eyes.
