How to get rid of UNDER EYE BAGS FAST (the SAFEST ways) | 👁 Ophthalmologist @michaelchuamd

High-salt diet: Eating a lot of salty foods causes you to retain water and leads to swelling.
Allergies: Congestion and inflammation from allergies can sometimes exacerbate under-eye puffiness.
Medical conditions: Some health conditions such as thyroid problems can cause the eyes to become swollen.
Genetics: Having under-eye bags can be a physical characteristic that runs in your family. 
Natural aging process: Loss of firmness in the skin and muscles happens as you age.Cold compresses: Cooling the area lessens inflammation and swelling by reducing blood flow. You can place anything cold, such as an ice pack, frozen bag of vegetables, chilled cucumber slices or refrigerated spoons, over closed eyes for a few minutes.
Hemorrhoid creams: Some people pat over-the-counter creams designed for hemorrhoid treatment under their eyes. Product ingredients such as phenylephrine narrow blood vessels to reduce swelling. But use these products with caution: They may cause irritation in this sensitive area. Also, it’s important to keep this medication from getting in your eyes. 
Caffeine: Caffeine is a vasoconstrictor, meaning it constricts blood vessels. Many cosmetics companies sell eye creams with caffeine to reduce under-eye puffiness. You can also try resting chilled tea bags (caffeinated black tea) on closed eyes.
