FRECKLES

Freckles are simply localized pigment deposits in the skin. It is now believed that individuals who develop freckles easily are born with two different types of melancocytes (the cells that produce the pigment melanin). One type of the melanocyte produces normal skin tanning when exposed to the sun while the other produces a permanent, pigmented spot. Freckles are the permanent and there is nothing that can be done about them once they have developed. (There are special chemicals which are said to help get rid of freckles, but I don't recommend them because they could cause skin problems of their own.)
