"i have had moderate adult acne for many years, and over the counter never touched it. besides the regimen was always annoying and time consuming.  i started this about 2 weeks ago after asking my pcp for something to help my acne, as i am getting married in may. i have seen a huge improvement in 2 weeks.  my skin tone has also improved.  i am very thankful for this medication and i use it twice a day.  it keeps pimples from becoming large and irritating."
