Usually, if they are not genetic eye bags, young people will get eye bags after sleep from drinking too much water before they sleep. I can't explain why, but it's the truth. I also experience such eye bags in the morning when i wake up because of taking much of water last night. Don't worry, the eye nags will gone not long ago. If you want to reduce it, here a way that may help you: Just lay down, close your eyes, and put to a thin lemon slice on each of your eyes. Relax , and do not close your eyes too tightly, but also not open your eyes. Keep it about 15-20 minutes. Then, splash cold water to massage your eyelid. It could be work to reduce the nags under your eyes.
