The appearance of dark circles under your eyes is often due to a lack of sleep, but they can also be caused by food and environmental allergies, nutritional deficiencies, hormonal changes, and aging.
Dark circles caused by food and environmental allergies are called “allergic shiners” and are best treated by identifying possible allergens you’ve come in contact with – and then avoiding them for 10 days to see if the skin tone under your eyes returns to normal.
If that doesn’t work, start by increasing the amount of water you drink each day. Dehydration can lead to the appearance of dark circles because the skin around your eyes is very close to the underlying bone, and a lack of fluids can cause blood vessels to become more visible.
In addition to drinking more water try using arnica gel or skin care products containing arnica.
Arnica is a flowering plant in the sunflower family. Its yellow petals are collected and dried for use in herbal remedies and medications. Arnica helps boost the circulation of white blood cells which helps accelerate healing. It also has powerful anti-inflammatory properties that alleviate swelling and reduce the appearance of dark under eye circles.
Most natural arnica gels will help with periodic dark circles, but to keep those dark circles away its best to use a natural skin care product that contains arnica daily.
