Teacurry Dark Circles Tea is made with special herbs that help your skin and lessen dark circles. Dark circles happen when you're tired or haven't slept enough. At first they might just look like shadows under your eyes but they can get worse over time. As you get older your skin gets thinner which makes dark circles more visible. Even sleeping too much can make them worse by causing fluid to build up making the dark circles stand out more because the skin under your eyes is thin.
