How many treatments will I need to treat Actinic Keratoses?

Current recommendations suggest 1 to 2 treatments are necessary to achieve results.  Recent data suggests approximately 90% of patients obtain significant improvement from this regimen.  In addition, precancerous lesions and sometimes very superficial skin cancers that are not yet visible on the skin can be cleared.  Improvement likely lasts years with the continued use of sunscreens and anti-aging creams such as retinoids.
