Eye bags come from aging, genetics, poor sleep, allergies, fluid retention, and salt.
Causes
- Aging: tissue and fat shift under the eyes.
- Genetics.
- Lack of sleep.
- Allergies.
- Fluid retention and salt.
- Smoking and sun exposure.
What helps
- Sleep 7 to 9 hours.
- Cold compress.
- Reduce salt.
- Treat allergies.
- Sunscreen.
Medical options
Fillers or lower eyelid surgery (blepharoplasty).
See a doctor

If swelling is sudden or in one eye.
Causes
Eye bags form from weakened tissue around the eyes, fat that bulges as support structures loosen, fluid retention and shadows from hollows. Aging is the main factor, since skin thins and collagen declines after 30. Genetics play a large role, and bags may run in families.
- Lack of sleep, salty food, alcohol, allergies and smoking worsen puffiness.
- Dark circles can come from thin skin showing blood vessels or from pigmentation.
- Sleeping flat can cause morning puffiness that fades during the day.
What helps

Cold compresses, sleeping with the head elevated, treating allergies, reducing salt and using sunscreen help. Caffeine eye creams give a temporary tightening effect. Cosmetic procedures include fillers, laser resurfacing and lower eyelid surgery (blepharoplasty), which costs about 3,000 to 6,000 USD in the US. See a doctor for sudden, one-sided swelling, pain or redness, or with thyroid symptoms like weight change or bulging eyes.
Causes
Eye bags come from fat pads that bulge as supporting tissue weakens with age, fluid retention, lack of sleep, allergies, salt intake and genetics. Dark circles are linked to thin skin and pigment.
What helps
Cold compresses, sleep elevation, reduced salt and allergy treatment help. Procedures like fillers and blepharoplasty are options. See a doctor for one sided or painful swelling.
Age related changes
With aging, the orbital septum weakens, allowing fat to bulge, and lower eyelid skin loses collagen. Allergies and rubbing cause swelling. High salt intake leads to morning puffiness. Genetics is the strongest predictor.

Treatments and costs
Caffeine eye creams constrict vessels slightly, cold spoons reduce swelling for a short time. Medical options include fillers for tear troughs (600 to 1,500 USD per treatment) and lower eyelid blepharoplasty, with average surgeon fee about 3,500 USD in the US according to ASPS. Persistent one sided swelling or sudden puffiness with redness requires a medical check.
