Even after a full night's sleep, you can still look tired when you have dark, puffy patches under your eyes. Sometimes called “panda eyes,” the dark rings can ruin an otherwise good morning in an instant. There are some simple lifestyle changes you can make to prevent or decrease the chances of under-eye problems becoming a daily occurrence.

Eat healthy food. Diet can affect the severity of under-eye circles and puffiness. An excess of salt in your diet, due to eating too many processed foods, can lead to fluid retention in the under-eye area. Vitamins A, C and E are important to the health of your skin, so increase your intake of fruits and vegetables by drinking fresh-squeezed juices or smoothies. Also, do not smoke, and moderate your amount of alcohol intake.

Drink plenty of water. When you are dehydrated, the blood vessels in your skin may become more visible as the skin retracts, giving you blotchy skin, especially in the eye area. Drinking plenty of water keeps your skin plump and smooth, minimizing the appearance of sagging skin.

Using cold therapy, such as cold cucumber slices, cold, moist teabags and cold spoons, also reduces the puffiness around the eyes. This is also a great way to unwind after a long day.

There are many cosmetic solutions to your under-eye woes, but it is a good idea to have a healthy base with which to work first, as it helps your skin care products work more effectively. You might even be able to reduce the amount of product you use on your face, allowing you to use a high-quality skin care product that still saves you money in the long run.
