No subjective symptoms. The rash becomes darker and more numerous after sun exposure in the summer, while it becomes lighter or disappears in the winter. There is often a family history.

Causes of freckles

1. Genetic factors: The freckles gene produces melanin under exposure to the sun, forming freckles. Some parents do not have freckles, but their children develop them later. This shows that many people who carry the freckle gene do not show it in their adolescence, but show it later under exposure to the sun. Some pregnant women did not have freckles before, but hormonal changes during pregnancy stimulate the formation of freckles. These women are recessive carriers of the freckle gene.

2. Long-term exposure to the sun. The sun's ultraviolet rays make the skin's melanocytes active. The damage of ultraviolet rays to the skin causes the skin's metabolism to be weakened, resulting in the inability to excrete melanin normally. Over the years, a large amount of melanin accumulates to form freckles.
