Age spots on skin? What exactly are age spots?

Age spots. The term ‘age spots’, or lentigines, refers to the brownish spots that, over time appear on your face and body as a result of overexposure to the sun. As we age our skin is subjected to more and more sun damage.
Caused By Sun. Age spots are actually caused by the sun (not age). So, the best way to reduce them is to avoid sun exposure. Daily use of a sunscreen with spf 30 or higher is required (at a minimum). If you work or play outside for more than 2 hours, re-application of the sunscreen is essential.
