Anti-tan is the process of reducing melanin pigment in the skin to get a whiter complexion. Those with darker complexions have more melanin, and the amount of melanin influences the shade of a person’s skin. Melanin is produced by cells known as melanocytes. The amount of melanin in a person’s skin is determined by genetics. Exposure to the sun, the degree of skin injury, and chemical exposure all have an impact on melanin formation.
