Even though puffy eyes can sometimes be caused by genetics, allergies or personal skin characteristics, good home remedies include putting cucumber slices (as cliché as it sounds!) over your closed eyes because of this veggie antioxidants that help to reduce the swollen skin. If you are doing this regularly, you can switch it up with chilled tea bags or ice compresses too. Other good practice to avoid them is drinking enough water (or liquids for that matter), as puffy eyes and dark circles are sometimes caused because of dehydration. Hope this helps!
