No, dark skin cannot permanently become fair. Skin color is determined by melanin, a pigment produced by our bodies. The amount of melanin we inherit from our parents determines our natural skin tone, and it doesn't change permanently.
While things like sun exposure or certain medical conditions can temporarily alter skin color, these changes are not permanent and our natural skin tone will eventually return.
For example, a person with dark skin might tan in the sun, making their skin appear lighter. However, this tan will fade over time, and their skin will return to its original color.
Similarly, some medical conditions can cause temporary skin discoloration, but these changes are usually treatable, and the skin will return to its normal color once the underlying condition is addressed.
