Bags under the eyes are not a catastrophe. You can live for 150 years with bags under your eyes, and nothing terrible will happen to you. But they are a sign of excess puffiness, and it’s best to deal with that and reduce it. Why do bags appear? Because the subcutaneous fat in that area retains extra water, as does the rest of the body. To get rid of bags under your eyes, you need to eliminate overall puffiness and then improve the venous and lymphatic flow from the face and head.
To do this, work on your neck and perform comprehensive lymphatic drainage. This can all be done at home—no need to go anywhere. Create a comfortable environment, do lymphatic drainage, and do a simple facial massage; things will improve.
