hehe. those natural solutions work but only temporarily though. Cucumber works well for puffiness because it's cold. So technically it's not so much the cucumber but the coldness. Therefore to reduce puffiness, you can also put like a refrigerated metal spoon or those cold eye mask. but please note that this is a temporary effect meaning that if you just had a big fight with your bf and have super puffy eyes from all the crying but promised to meet up with your friends, you can get away with it by putting cold cucumbers on your eyes

As for potatoes, it's the potassium that helps with the dark eye circles. but again. temporary effect. so maybe if you do it everyday then everyday you'll have bright eyes
