Dark circles under the lower eyelids are common in men and women. Often accompanied by bags, dark circles can make you appear older than you are. To make matters worse, they can be challenging to get rid of. Though they can affect anyone, dark circles are most common in the elderly or having a genetic predisposition. Also, non-white ethnic groups have a much higher chance of having dark circles. Many things come into consideration when dealing with them such as staying up a few hours past your bedtime, extreme fatigue and aging are common causes when the orbital bone begins to thin, and we lose facial fat.
