Why so blue? The reason dark circles look blue is because skin only lets blue-violet wavelengths of light pass through it. As a result, only blue light is reflected back. So, if your skin is very thin the veins look – you guessed it – more blue.
Genetics get in the way If you inherited fair or thin skin under your eyes, blood vessels will be more noticeable at the best of times, let alone when you are tired.
Age is a factor Over time, skin loses collagen and thins so blood vessels become more prominent. Be aware sun exposure speeds up this process by damaging collagen fibres.
Allergies are a culprit Reactions to seasonal factors can trigger the release of histamines in the body, which in turn inflame blood vessels and cause swelling.
Pillow talk If your dark circles are the result of vascular issues, sleep on two pillows to stop blood building up under the eyes.
Chill out In the morning, try using a cool eye mask for a few minutes to constrict blood vessels.
Cream team Use an eye cream that is specially formulated to target dark circles as well as soften the delicate area, try Rénergie Multi-Lift Eye Cream, $105/15ml, Lancôme. If thinning skin is a problem, try Retinol Correxion Eye Cream, $35.50/15ml, ROC.
Food treats Enjoy a little dark chocolate, which is a rich source of flavonoids that are reported to help maintain the health of blood vessels. And foods with omega-3 fatty acids such as salmon and walnuts can improve blood flow.
Hmmm..if you insist!
Allergen alert If you are prone to circles under the eyes caused by allergies, try taking an antihistamine treatment before exposure to potential allergens to prevent a reaction.
Cover up For a quick fix: first apply eye cream, let it settle in, then pat a creamy skin-toned concealer over the area. To finish, press a little
loose powder on top to prevent it from creasing.
