The causes of large bags under the eyes include age factor, irregular work and rest, liver and kidney diseases. 1. Age factor: The skin under the eyes can gradually become loose with age, and the orbicularis oculi muscle and ligament structure will also deteriorate, resulting in fat bulging out of the orbital septum, which will eventually make the bags under the eyes grow bigger. 2. Irregular work and rest: When you don’t get good sleep and rest, such as insomnia, fatigue, overuse of eyes and so on. This will lead to the appearance of dark circles and bags under the eyes. 3. Liver disease: when the liver’s metabolic ability or excretion ability decreases, can lead to edema around the eyelids, and the eye skin is thin, eye tissue relaxation, so edema is more obvious, so that the tendency of bags under the eyes will also be gradually aggravated. When the bags under the eyes become bigger, you should avoid excessive eye use, pay attention to regular work and rest, and if the symptoms are serious, it is recommended to go to the hospital for examination, to clarify the cause of the disease, and to carry out targeted treatment.
