Under-eye dark circles are a common concern that can affect individuals of any age. These dark circles can be attributed to several factors, including hollow tear troughs (the area between the cheek and lower eyelid), thin skin under the eyes, and pigmentation issues. The appearance of dark circles can be further accentuated by a lack of sleep, frequent travel, an unhealthy lifestyle, and the natural process of aging. These dark circles often give the appearance of fatigue and poor health, making them challenging to conceal with makeup alone.
