my daughter is having Dark circles kindly suggest what can be the reason and what should be done ?

A. hi Placing cold spoons on top of your child’s eyes may help relieve fatigue. Cotton balls soaked in cold water also work well in combating dark circles. Massaging your child’s eyelids gently when closed can help relieve stress temporarily. Iron-rich food like spinach can help increase the level of iron in the body, and over time, fight against dark circles caused by a deficiency of iron.
