Neck Darkening Not Always Due to Dirt

Kathmandu. Most people's facial color remains normal, but the neck gradually starts to look darker than the face. This difference becomes clearly known when the color of the face and neck is not the same when looking in the mirror.

Often people consider this to be dirt, sweat, or lack of cleanliness and start rubbing the neck hard. However, the darkness of the neck is not always due to dirt.
