One often seen skin concern found in adults over age 30 are age spots. They are caused by sun exposure. Genetics does play a part, with the condition passed on from parents to children. Age is not the direct cause of these types of skin spots, but cummulative exposure to the sun. Older people have simply been exposed for a longer time period. Age spots are not threatening. New spots will appear throughout a patients life. Many treatment approaches have been developed with effectiveness dependant on skin condition.
