Brown SpotBrown spots or “skin marks” are generally linked to sun exposure. They are therefore an after-effect of the sun and are not in themselves related to age (this definition does not include “age spots”). They can appear on people from the age of 25 -30.
As they are caused by the sun, they appear on exposed areas - face, neck, décolleté, forearm and the backs of the hands. (www.dermatonet.com)
