SECONDARY outcome
Timeframe: 12 weeks post- final treatmentPopulation: Based on subject questionnaires, 90% of subjects reported improvement (clearing) in benign pigmented lesions at 12 weeks post- final treatment. Scores \> or =1 indicate improvement.
Level of Satisfaction with Improvement (clearing) in solar lentigines as assessed by participants, as measured by spot Improvement: 3=Very Much Improved, 2=Much Improved, 1=Improved, and 0=No Change.

SECONDARY outcome
Timeframe: During treatmentsSubjects graded the level of pain associated with each laser treatment, using a 0-10 scale where 0=no pain and 10=worse possible pain, then averaged to get the mean across the treatments.
