Why is My Face Getting Darker Without Sun
To understand why is my face getting darker without sun, it is important to first know how skin color works. Skin color is mainly determined by melanin, a natural pigment produced by melanocytes in the skin. Melanin protects the skin from damage caused by ultraviolet radiation, toxins, heat, and inflammation. When melanocytes become overactive, they produce excess melanin, leading to darker skin, pigmentation, and uneven tone. While sunlight is a common trigger, it is far from the only factor that stimulates melanin production.
