Nothing says “exhausted” more than dark under-eye circles—whether from lack of sleep, genetics, allergies, or a breakdown of the skin due to aging, rubbing, smoking, or sun damage. When under-eye skin thins, it exposes the blue veins and vessels underneath.

• If the darkness is the result of pigment, eye creams with skin-lightening ingredients like vitamin C, licorice root, kojic acid, soy, or yeast extract may fade discoloration and pigmentation, says Fusco. Use an eye cream with a minimum SPF of 15 to prevent more melanin from building up.
• “Though there’s little research to prove vitamin K erases dark circles, there is anecdotal evidence that it works,” says Baumann. “Products that also contain retinol help the vitamin K penetrate better.”
