Dark circles under the eyes can be caused by lack of sleep, stress, genetic factors, aging or nutritional deficiencies. Since the skin is very thin in this area, the visibility of blood vessels increases and dark circles may form. Regular sleep, plenty of water consumption and a balanced diet are important to alleviate dark circles under the eyes. In addition, eye creams containing caffeine, vitamin E and vitamin C can be effective in reducing bruises. Cold compress applications temporarily reduce puffiness and bruising in the under-eye area. Cucumber, potato slices and green tea bags are among the natural solutions. These products soothe the skin thanks to their antioxidant and anti-inflammatory properties. Gentle massaging around the eye area can improve blood circulation and reduce the appearance of these bruises. Using sunscreen can also help protect this delicate area from the harmful effects of the sun. With regular care and patience, the appearance of dark circles under the eyes can diminish over time.
