Drinking coffee may provide some benefits for reducing the appearance of dark circles under the eyes due to its caffeine content. Caffeine can help to constrict blood vessels, reduce inflammation, and improve circulation, which can make the skin appear brighter and less puffy. However, it's important to note that drinking coffee alone may not be enough to completely get rid of dark circles under the eyes. Dark circles can be caused by a variety of factors, including genetics, aging, lack of sleep, and allergies, and addressing the underlying cause is the key to treating them effectively. In addition to drinking coffee, you may want to try other remedies such as getting enough sleep, using a cold compress, managing allergies, and using eye creams with caffeine or other brightening ingredients to help reduce the appearance of dark circles
