Are freckles genetic? Some people are genetically predisposed to develop freckles. People with light skin and red or blonde hair are more likely than others to have them. Freckles are a form of hyperpigmentation that occurs as a natural defense mechanism again sun damage. As a result, they don’t tend to appear before age two.
Decades of research have shown that ephelides are a heritable trait and that genes like MC1R have a big role to play in this—however, the amount of color in those freckles may be influenced by a combination of genetics and environment.
