What factors are related to having dark skin?
Dark skin is related to sun exposure and diseases. Many diseases, such as endocrine system diseases and chronic consumptive diseases, can lead to the formation of melanin in the skin. If daily sun protection measures are not taken properly and skin hydration is not paid attention to, it will also lead to the formation of melanin in the skin, making the skin dark. It is necessary to clean and moisturize the skin regularly.
1. UV Exposure Causes Skin Darkening
UV rays are the primary culprit for darkening skin. Long-term exposure of the skin to UV rays can lead to the formation of melanin. UV rays promote melanin production, not only causing skin darkening but also promoting the development of pigmentation. Solution: It is essential to take daily sun protection measures, including applying sunscreen, regardless of sunny or cloudy days. Even on cloudy days, there are residual UV rays that can damage the skin.
2. Chronic Infections and Diseases Affect Skin Pigmentation
Chronic infections and diseases affecting the liver and kidneys can lead to changes in skin pigmentation. As we all know, the liver is an organ of metabolism, and the metabolic products need to be excreted through the kidneys. If there are abnormalities in the liver or kidneys, toxins in the body cannot be expelled in time, leading to skin darkening.
3. Allergies Cause Skin Darkening
Certain skin diseases caused by food allergies, such as allergies to ginger, chili, leek, and even fish, shrimp, and seafood, can induce allergic reactions in the skin, leading to the appearance of allergic urticaria. These allergies are difficult to treat and can leave pigmentation deposits, causing skin darkening.
