Don't Settle For Dark Circles
Dark circles are the result of blood that pools in the vessels that lie close to the skin's surface, which is why they can be almost impossible to hide. They can can also arise when fat bulges out because light cannot be reflected properly, casting a shadow under the eye. Sun exposure, allergies, and lack of sleep are less likely but still possible culprits.
There are several ways to deal with dark circles, starting at the product level. Hydroquinone can help to lighten the area to some degree is the problem is more about discoloration than shadowing. Excessive sun exposure intensifies dark circles, so it's important to always wear a product with SPF, as well as sunglasses.
Another way to counteract dark circles, if they are a result of excess fat, is with hyaluronic acid fillers. When injected into the shadows under the bag, they can camouflage darkness by plumping up the area.
For the most dramatic difference, lower eyelid surgery should be performed. Once the protruding bag is tightened or removed, there is no puffy area to create a shadow, helping to diminish dark circles.
