Hypopigmentation is the loss of skin color. It is caused by melanocyte or melanin depletion, or a decrease in the amino acid tyrosine, which is used by melanocytes to make melanin.

Treatments

Often, hypopigmentation can be brought on by laser treatments; however, the hypopigmentation can be treated with other lasers or light sources.^[1]
