Why are freckles called ephelides ?

  FRECKLES : Freckles clusters of concentrated melaninized   cells which are most easily visible on people with a fair complexion . Freckles do not have an increased number of the melanin-producing cells, or malanocytes , but instead have melanocytes that overproduce melanin granules  changing the coloration of the outer skin cells .  As such, freckles are different from lentigines   and moles  which are caused by accumulation of melanocytes in a small area. Freckles can appear on all types of skin tones.  WHAT ARE THE CAUSES OF FRECKLES ? Ephelides are an inherited characteristic. People with many ephelides have at least one copy of a variant MC1R gene,  which is the same variant that causes red hair. Freckles in non-Caucasians are associated with a different variant of the gene. The pigment -forming cells, melanocytes , produce more pigment than usual in ephelides. The pigment is packaged as...

Freckles due to increase in the amount of dark pigment called melanin and an increase in the total number of pigment producing cells called melanocytes.  CAUSES OF FRECKLES Freckles are a result of a genetic predisposition and sun damage caused due to excessive exposure to UV rays . the skin absorb UV rays and produces excess melanin that results  in pigmentation in small patches .
