Many women complain of having “dark circles”, which are mainly due to the grayish color of the skin under the eyes, giving the impression of not being well rested or aging. From a medical point of view, there are several causes of dark circles under the eyes: 1. Pigmentation or discoloration of the lower lid skin. Commonly, there are chloasma or brownish-blue spots, in addition, it can also be caused by improper use of cosmetics, because the skin around the eyes is very thin, so it is easy to produce chronic irritating inflammation, over time, it will form pigmentation or discoloration; 2. Subcutaneous thickening of veins or venous stasis. This condition is often seen in fair-skinned people, their blood vessels can be faintly visible through the skin, in the case of strain or lack of sleep can lead to poor blood flow, dark-colored venous blood stagnation within the blood vessels, through the skin on the formation of dark circles; 3. The shadow of eye bags. The fat protruding from the orbital area of the lower lid causes bags under the eyes, and a shadow is formed underneath it under the action of light, forming dark circles; 4. Fine wrinkles on the lower eyelid. As we age, the skin also gradually relaxes. Middle-aged women tend to have many tiny wrinkles in the lower eyelid area. With the same light exposure, the wrinkled area will absorb more light than the smooth skin area, giving a dull feeling and causing dark circles under the eyes. Since there are many causes of dark circles under the eyes, different treatments are needed for different causes. For dark circles caused by skin pigmentation or discoloration, you should try to avoid stimulating the skin in that area, visit a hospital to find ways to reduce inflammation, and use medication or laser to treat the pigmentation or discoloration. If the veins are stagnant due to strain, you need to adjust your work and rest schedule to ensure sleep and rest, and use massage and physical therapy to improve blood circulation. For dark circles caused by bags under the eyes, the effect can be corrected by under-eye bag plastic surgery. In the case of the gray lower eyelid area produced by fine wrinkles, the appearance of dark circles should be improved by treating the wrinkles with laser or radiofrequency skin tightening, filler injections or surgery.
