Causes of prolonged melasma at the outer corners of the eyebrows:
1. Ultraviolet radiation: Long-term exposure to sunlight, especially on protruding areas of the face such as the outer corners of the eyebrows, can easily lead to UV radiation damage. This stimulates melanocytes to secrete excessive melanin, resulting in pigment deposition that forms melasma.
2. Endocrine disorders: Factors such as high life stress, irregular作息 (作息 should be translated as "作息" is commonly used for "lifestyle or daily routine" in Chinese medical texts, but no direct equivalent exists in English; thus, it should be translated contextually), and unbalanced diet may lead to hormonal imbalances within the body. These imbalances can affect melanin metabolism and distribution, triggering melasma.
3. Age-related factors: With aging, the skin's metabolic capacity gradually weakens, and the rate of melanin metabolism also slows down, thereby increasing the risk of developing melasma.
4. Genetic factors: The occurrence of melasma shows a certain degree of familial clustering, suggesting that genetic factors may play a role in its development.
