freckles are a form of irregular tanning in which the melanin that is normally produced by a suntan is concentrated in clusters of UV-sensitive melanin producing cells (melanocytes) instead of evenly darkening the skin like in other skin types which have a more even distribution of melanocytes.

They’re common in redheads because of their prevalence in northern Europeans who have the MC1R gene.
