Dark circles under the eyes are a common problem that can make people look tired and older than they actually are. There are many factors that can contribute to dark circles, including genetics, aging, fatigue, and sun exposure. While there is no one-size-fits-all solution to avoiding dark circles, there are a number of things that can be done to reduce their appearance.
One of the most important things to do to avoid dark circles is to get enough sleep. When you are well-rested, your skin will be more hydrated and less likely to show signs of fatigue. Aim for 7-8 hours of sleep each night.
