Freckles are small, tanned brown spots on skin. They usually arise on the parts exposed to the sun. they arise due to excess production of melanin in the body. The production of melanin increases because of the increase in cells named melanocytes. Freckles are harmless and do not evolve into any serious disease. Repeated exposure sun usually
darkens and makes them more apparent the spots whereas the winter sun brightens them.
The spots are uniform in shape and size all over the affected area. People with fair complexion are more prone to freckles.
