Dark circles under the eyes are dark or discolored skin that appears under the eyes. They can be caused by a variety of factors, including:

Genetics: some people may be more prone to developing dark circles under the eyes due to their genetic makeup.

Allergies: swelling and inflammation in the eyes caused by allergies can lead to dark circles.

Lack of sleep: not getting enough sleep can cause the blood vessels around the eyes to dilate, leading to dark circles.

Dehydration: when the body is dehydrated, the skin around the eyes can appear dull and discolored.

Medical conditions: some medical conditions, such as eczema, psoriasis, and thyroid problems, can also cause dark circles under the eyes.

Aging: as we age, the skin around the eyes becomes thinner, and the muscles and fat that support the eyes weaken, causing dark circles to appear.

Treatment options for dark circles under the eyes include:

Topical creams and gels: these can help to hydrate and brighten the skin around the eyes, reducing the appearance of dark circles.

Cold compresses: placing a cold compress on the eyes can help to constrict blood vessels, reducing dark circles.

Caffeine: caffeine is a natural diuretic that can help to reduce puffiness and swelling and help reduce dark circles.

Eye massages: gently massaging the area around the eyes can help to improve circulation and reduce dark circles.

Drinking more water: drinking more water can help to hydrate the skin and reduce dark circles.

Vitamin k cream may help to reduce the appearance of dark circles by improving circulation around the eyes. Sunscreen reduces sun damage which can cause dark circles.
