Puffy bags under the eyes are caused by the weakening of the tissue structures and muscles supporting the eyelids, which can cause the skin to sag and fat that usually surrounds the eye to move into the area below the eyes. Fluid may also accumulate below the eyes, making the area look puffy or swollen. Several factors can cause or worsen this effect, including aging, fluid retention, lack of sleep, allergies, and smoking. Some medical conditions such as thyroid problems can also cause the eyes to become swollen. The loss of firmness in the skin and muscles happens as you age, which allows the fat surrounding the eye to bulge out, creating that bubble-like appearance.

Puffy bags under the eyes are usually a cosmetic concern and dont require medical treatment. Home and lifestyle treatments may help reduce puffiness. For example, using a cool compress, cutting down on fluids before bedtime, limiting salt in your diet, not smoking, and getting enough sleep can help reduce or eliminate bags under the eyes. Caffeine is a vasoconstrictor, meaning it constricts blood vessels, and many cosmetics companies sell eye creams with caffeine to reduce under-eye puffiness. Laser resurfacing, chemical peels, and fillers are various wrinkle treatments that can improve the appearance of puffiness under the eyes. If youre concerned about the appearance of under-eye swelling, medical and surgical treatments are available, but treatment may not be covered by medical insurance if its done solely to improve your appearance.
