By limiting your sun exposure, you can decrease the possibility of age spots. Sun exposure before the age of 20 is the major factor that determines how your skin will look in later life. If you already have age spots, limiting your exposure to the sun can help prevent them from enlarging or darkening.
To protect your skin from the sun, wear long-sleeved shirts, pants and a hat. Use sunscreen if you will be outside for more than a few minutes. Avoid being in the sun during midday (10 a.m. to 3 p.m.), when the sun's rays are the most intense.
