What Are Freckles?
5. Ephelides
Ephelides occur due to a combination of genetics and exposure to sun. They may be visible at a young age (2 to 3 years old) after there is exposure to the sun. Ephelides usually appear on skin that is exposed to the sun such as the face, neck, shoulders, chest, and arms.
In some, these spots may fade during the winter months and reappear in the summer months. Ranging from 1 to 2 millimeters, they may be larger if the spots merge. Ephelides are often light to dark brown flat macules. The border of the lesion is often poorly defined and may be irregular, merging into larger patches. It can be any shape and is most commonly round.
