Dark circles under the eyes are a common concern that can make people look tired and listless. Many people want to get rid of them quickly, but what exactly causes dark circles? And how can they be prevented and treated?
I. The causes of dark circles include the following:
1.先天遗传或后天性眼皮色素沉着增加 Increased pigmentation of the eyelids due to genetic or acquired factors;
2. 眼皮老化松弛，皮肤皱在一起造成外观肤色加深 Sagging eyelid skin due to aging, causing the skin to wrinkle and appear darker;
3. 眼袋出现造成阴影 Shadows caused by the appearance of bags under the eyes;
4. 眼眶内下侧凹陷形成泪沟(naso-jugal groove)进而形成阴影 Tear troughs (naso-jugal grooves) formed by sunken areas below the eye sockets, leading to shadows;
5. 眼皮静脉血流滞留造成皮肤眼色加深 Stagnation of venous blood flow in the eyelids, causing deeper skin discoloration.
Some people may experience a combination of these causes.
