I think Freckles are beautiful.
Me too! They mostly occur on people with a fair complexion.
I supposed that is why so many Scots Irish have them.
They must be outside often because spending a lot of time in the sun can also lead to the formation of freckles.
I have heard that before, but wasn't sure it was true.  I wonder what causes them to form in sunlight?
When you are exposed to a lot of UV-B radiation this increases melanin production and causes freckles to become more visible.
