Dark circles under the eyes are getting heavier and heavier may be caused by poor blood circulation, trauma, individual differences and other reasons. 1. Poor blood circulation: prolonged staying up late, lack of sleep or prolonged use of electronic products may lead to eye fatigue, which leads to slow venous blood flow to the eyes, thus leading to the production of dark circles under the eyes, if you stay up late for a long period of time, it will lead to dark circles getting heavier and heavier. 2. Trauma: Orbital trauma can lead to blood pooling around the eyes, forming dark circles, which may become more and more serious if not treated in time. 3. Individual differences: some people are born with heavier circles under the eyes, which can be left untreated if there is no discomfort. If the dark circles are getting heavier and heavier, you should pay attention to rest, and if they don’t get better, you should consult a doctor in time.
