Freckles are flat, circular spots that typically range in the size of the head of the needle. The spots develop randomly on the skin, especially after repeated exposure to sunlight and particularly in people of fair complexion. Freckles vary in colour. They can be red, yellow, tan, light brown, brown or black. But they are always darker than the skin around them. There are two basic types of freckles i) ephelides ii) lentigines. Ephelides is a hereditary factor and lentigines appears because of excessive development of melanin.
