"i used this medication for 2 years. it took approximately 4 months of using it once a day to see the full results. it totally curbed my oily skin and reduced my breakouts significantly, though i would still have 1-2 pimples at any given time. in the last year of use, i applied it twice a day and used  an spf50 sunscreen with it. i was finally starting to see my scars fade when my doctor switched my medication:( i loved benzaclin, and found it affordable since i have insurance."
