What causes darkening around the eyes?

Under normal circumstances, darkening around the eyes may be caused by individual differences, prolonged lack of sleep, pigmentation, keratitis, hepatitis, or other reasons. If discomfort arises from any of the above conditions, medical attention should be sought immediately to prevent worsening. The specific analysis is as follows:

1. Individual differences: In some individuals, the capillaries around the eyes may be more fragile, or the skin around the eyes may be thinner, making blood vessels and pigments more visible, thereby causing darkening around the eyes. This typically does not affect health and is generally not a cause for concern.

2. Prolonged lack of sleep: Chronic sleep deprivation can disrupt the body's endocrine system, including elevated cortisol levels and increased melanin production, leading to increased pigmentation in the skin around the eyes and resulting in a darkened appearance. It is recommended to maintain a regular sleep schedule with early bedtime and early rising.

3. Pigmentation: Certain environmental factors or improper use of cosmetics may increase skin pigmentation around the eyes, causing darkening. This may be related to ultraviolet exposure, certain ingredients in cosmetics, or frequent use of specific skincare products. It is advisable to apply sun protection and use mild, non-irritating cosmetics, which may help improve the condition.

4. Keratitis: Keratitis refers to inflammation of the corneal tissue, which may be caused by bacteria, viruses, allergies, or other factors. Darkening of the skin around the eyes may result from ocular inflammatory responses due to keratitis. Treatment under medical guidance may include medications such as tobramycin eye drops, methylprednisolone tablets, and fluconazole eye drops.

5. Hepatitis: Hepatitis may lead to systemic metabolic and endocrine disturbances, thereby affecting the condition of the skin around the eyes, possibly manifesting as darkening. It is usually accompanied by other symptoms such as jaundice and abnormal liver function. It is recommended to follow medical advice and use medications such as azathioprine tablets, recombinant human interferon α2b injection, and Anluo Huaxian pills to alleviate the condition.

In daily life, consuming more foods rich in vitamin C, vitamin E, and antioxidants—such as fresh vegetables, fruits, and nuts—can help improve skin condition and reduce darkening around the eyes.
