Under-eye hollows and dark circles are common cosmetic concerns that can make people look tired, aged, or unwell. These issues occur when the skin beneath the eyes appears darker and sunken. Under-eye hollows, also known as tear troughs, form as the skin thins and loses volume over time, often due to aging, genetics, or lifestyle factors like lack of sleep and dehydration. Dark circles, on the other hand, can result from a combination of factors, including pigmentation issues, blood vessels showing through thin skin, or shadowing from hollows. While these conditions are typically harmless, they can impact one’s self-confidence. Solutions range from skincare products and lifestyle adjustments to treatments like dermal fillers, which help restore volume and brightness to the under-eye area.
