Extensive sun damage can cause dark age spots and brown spots on exposed areas of the skin.

Recent health concerns about repeated hydroquinone exposure suggest that the best path to treating dark age spots may be a professional skin treatment. Dermatologists use lasers and intense pulsed light to treat dark age spots.
