What causes yellowish-brown spots under the eyes?
Disease description:
I have recently developed melasma on my eyelids, which directly affects facial aesthetics. What causes melasma to develop on the eyelids?

The causes of developing melasma under the eyes include:
1. Skin aging: With age, skin metabolism slows down and melanocyte function declines, leading to pigmentation and the formation of melasma.
2. Ultraviolet radiation: Prolonged exposure to UV light stimulates melanocytes to produce more melanin, thereby promoting the formation of melasma.
3. Endocrine factors: Changes in sex hormone levels, such as fluctuations in estrogen and progesterone, may also stimulate melanocytes to secrete more melanin granules, leading to the development of melasma.
4. Genetic factors: Melasma has a certain hereditary tendency. If there is a family history of melasma, an individual's risk of developing the condition may increase.
5. Lifestyle factors: Insufficient sleep, use of low-quality skincare products, and an unbalanced diet may negatively affect the skin and trigger or worsen melasma.
6. Disease factors: Chronic diseases such as diabetes and chronic hepatitis may affect the body's metabolism and endocrine system, indirectly leading to the formation of melasma.
